Forklift Model and Serial Numbers Debunked: Clark Part 1 

Anyone who has been part of the forklift world for a while will tell you that it’s a numbers game. Specifically, a model and serial numbers game. These two numbers can tell you almost anything about your lift. However, model and serial numbers and their jumbled-together numbers aren’t universal for every forklift. Even though they look similar (or like they have no meaning at all), most manufacturers create model and serial numbers that give the forklift operator specific information about that unit. Since the wholesale business sees forklifts from almost any dealer, we have put together a series of blog that will help you break down the model and serial numbers of various forklift companies you are more than likely to come across. Let’s start with Clark.

Over the years, Clark has changed their model and serial numbers as their fleets grew. So, we will start with earlier models and focus on model years 1969 through 1994.

Knowing Your Carriage Class

A forklift carriage is the part of the forklift that is installed on your mast to support the load backrest, forks, and other attachments. Knowing your carriage class is important when it comes to knowing what your lift is capable of. The carriage classes are rated 1-5 and depend on the space from the top of the upper bar to the bottom of the lower bar. Knowing these measurements will help you find attachments that fit your piece of machinery. Along with this info, you can also determine the capacity of your lift from the carriage class—to a certain degree. Take a look at the chart below to compare carriage sizes:  

Carriage Class:



Class 1



Class 2



Class 3



Class 4



Class 5




**While the carriage capacity can give you some idea of your machine’s lifting capability, it is only one piece of the puzzle. When determining how the carriage and your chosen attachments affect the load capacity of your forklift, it is always best to rely on the information provided on your data plate.

This chart is just the beginning of finding a piece of equipment and attachments to fit your needs. To make sure you are operating at full capacity, contact the Greyson Sales Team today.




Solid Vs. Air-Filled Pneumatic Tires

When it comes to deciding which kind of forklift you need in your facility, one of the biggest considerations is the type of tire you're going to need. While the common question is cushion or pneumatic, did you know that there is more than one kind of pneumatic tire?

Solid Pneumatics are made completely out of rubber and wear down over time. They are used in applications where the environment is rougher on the tire and the machine. These tires are more durable and hold up better against punctures, etc. They also wear slowly, so you can run your forklift for a long time before needing to replace them.

Air-Filled Pneumatics are a lot like a car or truck tire. They are treaded and thicker than a smooth cushion tire and are made to be more versatile like a solid pneumatic. However, because they aren’t solid, they are more likely to be punctured. On the other hand, they tend to do better on softer ground than a solid pneumatic because they have more give.

The benefits of pneumatic tires are rideability and durability. Pneumatic tires absorb more impact than cushion tires (smooth indoor forklift tires) and make the ride more comfortable. They also last longer. If you are running your forklift anywhere that has uneven terrain or sharp debris, a pneumatic tire will hold up better against these challenges than a cushion tire, which will tear or chunk easier. 

If you are considering the tire type before you purchase a forklift, ask yourself these questions:

    1. Will this lift be used in a mostly indoor, outdoor, or dual application?
    2. What kind of terrain will you being driving over? Smooth, rough, soft, or a variety?

If you’ve answered these two questions and find yourself doing a lot of outside work in a rough or varying environment, then you will most likely be looking for a pneumatic forklift.

11 OSHA Designations for Forklifts

It’s no secret that OSHA has certain inspection requirements when it comes to material handling equipment and the environment that equipment will be operating in. And while you may be running the properly rated model for your facility, do you know what that OSHA rating means?

OSHA has 11 different designations for forklifts that let operators know what precautions have been taken against fire hazards when constructing that piece of equipment:


  • G- Gas units with the minimum safeguards against fire hazards.
  • GS- additional safety measures to exhaust, fuel, and electrical systems.


  • D- The standard rating for a diesel unit and has no extra safeguards to the exhaust
  • DS- additional safety measures to exhaust, fuel, and electrical systems
  • DY- additional safety measures AND lack any electrical equipment

Liquid Propane Gas

  • LP- Liquified petroleum gas units with the minimum safeguards against fire hazards.
  • LPS- additional safety measures to exhaust, fuel, and electrical systems. They are designed to work where an LP unit is not suitable.


  • E- Electrical units with minimum safety guard against fire hazards
  • ES- has additional safeguards for the electrical system that prevent emission of dangerous sparks and limit surface temperatures
  • EE- electric motors and all other electrical equipment is completely enclosed on the unit.
  • EX- electrical fittings and equipment are designed to be used in an environment with flammable vapors and dusts.

A Note on forklift modifications: When making modifications to a forklift or other piece of equipment, make sure that the change won’t void the rating. Certain additions could negate the safety measures taken to make that unit spark or fireproof. Always make sure that you know what can be added to your equipment that won’t affect its capability to operate in your facility.



Buy, Rent, or Lease a Forklift: 3 Benefits to Each Option 

Adding material handling equipment to your operation, whether you need it for full shifts or one shipment a month, is a big undertaking. Aside from the type, size, and specifications to consider, you need to think about the most cost-effective way to acquire equipment. Below are 3 of the top reasons for buying, renting, or leasing your forklifts. 

Why buy? 

1. You can customize the lift to your needs. Every location is different. Maybe a standard 3-stage, 4-wheel sit-down unit just isn’t quite right. When you purchase a new unit, you can build the truck to your specific needs. 

2. Unlike renting or leasing, you get more out of your lift at the end. You own that piece of equipment, and you can do what you want with it.

3. There is no liability. At the end of a lease/rental, vehicles are expected to come back to the dealer under a certain number of hours and without any significant damage. If you violate these terms, you could end up paying more out of pocket at the end. 

Why Rent? 

1. Most rentals are short-term commitments. Aside from not being tied into a long-term deal, there is the opportunity to find the perfect piece of equipment for your facility because you can choose different machines to run for short periods of time.

2. If you choose to rent, odds are that the company renting to you will have a fleet of equipment ready to go. Unlike the lead times for buying a new piece of equipment (can be up to 3 months or more), you’ll have the equipment you need in a matter of weeks. 

3. Renting equipment can be a more money-friendly option for seasonal operations. There are times when more equipment is needed than others. Renting the amount of trucks you need seasonally helps you keep unnecessary equipment costs down. 

Why Lease? 

1. The monthly cost of a forklift is less when you lease it through a company. This way, you have a bit more cash in your pocket at the end of every month. 

2. Chances are, when you lease equipment, you’re getting newer, more updated models. Leasing lets you rotate different types of forklifts. You get to utilize the latest features and see how they optimize your workflow.   

3. You have a pre-determined replacement cycle when you lease, so you know when your lifts will be replaced, and you have the option to make changes to your fleet once your cycle is up.

Every operation's needs are different. Hopefully, we’ve given you some points to get you started, but these are just a few of the considerations you’ll take into account when deciding to buy, rent, or lese material handling equipment.


Why the Next Truck in Your Fleet Should be a Reach Truck

While a traditional “sit-down” forklift is an essential part of your material handling arsenal, in tight spaces it can feel more like you’re trying to fit a tank into a single-car garage. As business builds and inventory numbers grow, aisle-width tends to shrink.  So, what happens when your trusty sit-down unit can’t squeeze down them anymore? It’s time to consider adding a reach truck to your fleet. Here’s why.

Breaking down the Reach Truck (or narrow aisle forklift):

    • Electric units that run on 24, 36, or 48 Volt batteries
    • Capacity range: 3000-5500lbs
    • Narrow aisle reach trucks are stand-up rider units with easy maneuverability that are capable of tight turns in narrow spaces. The forks on a reach truck raise and lower but also extend outward away from the mast. There are single and double reach units. To counterbalance the load on extended forks, reach trucks are equipped with two “feet” that extend out in front of the unit. This makes the base of the unit wider so that it doesn’t tip forward when picking up product at full extension.
    • There are two different types of reach trucks: directional and multi-directional. The difference between the two is the way that they move through the warehouse. Unlike a “traditional” directional reach truck that turns around corners and into bays, multidirectional units eliminate the need to turn. Instead, the operator can, essentially, move the truck sideways to line product up in the proper place for storage.

Why a reach truck over the sit-down forklift?

    1. The biggest advantage of a reach truck is its ability to navigate narrow aisles and tiers. Because these units have a small turn radius and frame, they make it possible for warehouse owners to condense aisle space and make room for more racking and product. Even a tiny bit more space for a tiny bit more product means more profit.
    2. Narrow aisle forklifts also help to reduce accidents and risks because of their size and easy maneuverability. Unlike sit-down units that have to turn as the forks go into pallets—creating risk for product and racking damage, as well as “product push-through” (pushing pallets and causing them to fall from the opposite side of the rack)—operators have the ability to maneuver the truck so that the forks are aligned with the pallet and then extend the forks into the pallet precisely.
    3. Overall, reach trucks are more cost effective than a larger, sit-down forklift. The cost upfront is cheaper, but the money-saving doesn’t stop there. Narrow aisle units require less maintenance because they are run in a specialized application and experience less wear and tear than other units that are used in multiple environments and situations. They don’t need as many fluids because they operate in a simpler way, which saves on more maintenance costs.

Stock Order Pickers: The Run Down

Part of being a productive warehouse is making sure that you make the most out of your space and you are working in that space as efficiently as possible. If your operation is one that fills a lot of individual customer orders that contain multiple products, it is almost essential that you have a stock order picker. Here are some reasons why:

What is it? An order picker is a piece of equipment that is used in warehouse operations that specialize in filling individual customer orders. They are electric, narrow-aisle trucks that allow operators to go down closely placed together aisles and “pick” order items for their customers. Aside from fitting down narrow aisles, they also raise the operator up and down, allowing product to be placed in racking that is above reaching height.

Below are the most common specs for stock order pickers:

  • Up to 3000lb capacity
  • 24/36V/48V Electric
  • Single operator stand-up truck

There are three common order picker levels—Low-level, Mid-level, and High-level.

Low-level order pickers are single rider units that allow the operator to pick product for orders up to fifteen feet off the warehouse floor. Low level order pickers have a lower capacity rating of 500 to 2,200 pounds.  (Example here)

Medium-level order pickers have a general capacity of up to 3,000lbs and raise to 30 feet. (Example here)

High-level order pickers are also single rider units but have a higher capacity and raised height. High-level stock pickers can reach over 35 feet and up to 3,000lbs-3,500lbs. (Example here)

Here are the main benefits that come from investing in an order picker:

  • Because of their size and build, order pickers are space savers:
      • The move easily up and down narrow aisles that other sit-down units can’t turn in.
      • Because they don’t need to turn to retrieve product, warehouse floor space is saved. The heights they reach also make it possible to stack product without making picking an issue.  
  • Order pickers are also time savers:
      • Because operators don’t have to leave the machine, there is less time-consuming manual labor involved. There’s no need to push ladders or steps around to find product. This also means that multiple items can be picked at the same time, rather than one by one.
      • Being able to handle various sizes of product easily also helps productivity and saves time. Not to mention that with the machine doing the heavy lifting, workers don’t have to be as concerned with injury from carrying heavy product.

The Fork Positioner: Saving Time and Damage

There are a lot of bells and whistles that you can hang on your forklift to help you increase productivity. Previously, we discussed the side-shifter and its benefits. Today, we are going to spotlight the side-shifter’s tag-team partner—the fork positioner.

What is a fork positioner? A fork positioner is an attachment that allows an operator to move the forks on a forklift in or out automatically. They have hydraulic cylinders that attach to the tynes making it possible to move the forks by use of a lever. Some move one fork at a time, while others move both forks simultaneously. 

Why bother with a fork positioner?

  1. Like having a side-shifter, the addition of a fork positioner increases productivity by decreasing the amount of labor time it takes to move product. By allowing a driver to reposition just forks from where he or she is seated—and not have to readjust the entire forklift or drop the forks to move them manually—the job gets done faster.
  2. Because the operator can be more precise with fork and product placement, there is less damage in the long run. Not to mention that more accurate fork placement means less machine damage as well since there is less of a chance of running forks into a sturdy beam, pallet, or product.

Which fork positioner? Fork positioners come in a multitude of options. The type and specifications that you need are dependent on the application you will be using it in. For instance, will you be handling product that is carried in the center? If so, you should consider a positioner that allows the forks to come together completely. Most positioners will leave a small gap between the forks. Visa-versa, if you are handling a particularly wide product, there are wide opening options.

Aside from opening and positioning, there are a myriad of choices when it comes to fork types: hook-on, bolt-on, weighing forks (iForks) or telescopic forks are all compatible with fork positioners. With so many different specifications possible, a fork positioner can do more than just prevent pallet damage. It’s a surefire way to increase productivity.

Still not quite sure a fork positioner is worth the cost? Just contact our Greyson Sales Team here with any lingering questions.



 Blue Lights are the New Safety Special

Safety is always a major concern when operating material handling equipment. New safety innovations are a constant in the evolution of the forklift. Today, we are going to put the spotlight on one of the newest safety features and why blue light packages are becoming commonplace in the warehouse.

Blue LED lights mounted on the front and back of your forklift are a simple but highly effective way to:

    • Let operators know when there is another forklift is coming around corners or operating in adjacent aisles.
    • Inform pedestrians of oncoming forklifts and other material equipment.
    • Add one more level of indication for operators and those who work around material handling equipment by casting light up to 20 feet in front of or behind the machine.

Other features that make blue lights worth the investment:

    • Relatively easy installation.
    • A rated life of up to 50,000 hours.
    • Most (the most reputable) come with a lifetime warranty.
    • They are weatherproof and temperature proof from -22 to 185 degrees Fahrenheit.

While backup alarms, strobe lights, and horns are all tried-and-true safety measures, the addition of blue lights is just one more way to make sure your employees stay safe while working around or operating equipment. Ease of installation makes it a feature that can be added to any forklift, new or used.


Knowing Your Way Around Your Lift: Common Forklift Parts and Terms 

Forklifts have a lot of moving parts. So, when one of those parts stops moving and you need to call in the tech, it’s good to know the basic parts of your forklift. To help you maneuver through the forklift lingo, here’s a list of the most common forklift parts. We’ll start with the front: 

Forks: Sometimes referred to as “Tynes,” forks are attached to the front of the lift via the carriage and are used to carry loads. They come in varying lengths and widths according to need and can be adjusted on the carriage from left to right by sliding them. 

Carriage: The carriage is the support structure that sits in front of the mast and is where your forks are mounted. 

Load Backrest: The load backrest is the “gate”-like frame around your carriage that product rests against for a more secure carry. 

Mast: The mast ispart of the forklift that raises and lowers the load. Masts come in different types and have different specs according to the model of your lift. 

Tilt Cylinder: The tilt cylinder controls the amount that the mast can tilt forward and back. 

Hydraulic Lift Cylinder: The hydraulic lift cylinder controls the amount of vertical lift (how much the mast raises or lowers the carriage) of the mast. 

Cab: The cab is the main body of the forklift where the operator sits. It contains the steering wheel, brakes, controls, gauges, and pedals. 

Overhead Guard: The overhead guard is the frame around the cab of the forklift. It protects the operator from falling product and debris. 

Tires: Though this seems like an obvious definition, there are actually two different types of tires on a forklift. The steer tires are located in the back and control the direction of the lift. The drive tires are in the front of the truck and are fixed. They do not turn. 

Power Supply: Forklifts come with (generally) four power supply options: LP (liquid propane), gas, diesel, and electric (battery). The location of the power supply depends on which type of power you have. For instance, batteries are under the seat of your forklift, while the tank of a diesel forklift is mounted in the back. 

Counterweight: The counterweight is mounted on the back of the forklift and is used for exactly what its name implies—it balances the forklift by adding weight to the rear of the truck so that when a load is being carried or raised, the forklift will not tip forward. 

Got a lift with a lot of non-moving parts? It might be time to move on to a newer machine. The Greyson Sales Team can help you get back up and running with a quality piece of manufacturing equipment. Just contact us here.



Forklift History at a Glance

It’s not a secret that forklifts are the heavy-lifting backbones of any manufacturing facility. We rely on an estimated 855,900 forklifts (OSHA) in the U.S. to get the daily job done. But, for a piece of equipment that we work with every day, how much do we really know about the forklift and how it came to be the workhorse it is?

1917: Clark Material Handling in Kentucky was the first to create the sit-down, counter-balanced truck. They coined it the “Tructractor.” It had 3 wheels, a gas engine, reversed steering, and no brakes. It also lacked forks and was used to haul heavy loads. Initially, it was only for use in their own manufacturing but visitors—especially the military—recognized the practicality of the tructractor and began to ask for their own (Clark).

1920: Yale and Towne joins Clark in the industry with their introduction of the first battery powered low-lift platform truck (Yale).

1921: Clark unveils the first forklift—the “Truclift”—to use hydraulics to hoist material.    

1923: Yale releases the first forklift featuring tilted forks.

World War I&II: The forklift industry saw a boom in demand with the oncoming wars and manufacturing needs. Alongside its space-saving companion, the pallet, there came a need to stack product higher so that manufacturers could manage their space more efficiently.  Between 1939 and the later years of WWII, the number of forklifts in operation went from 500 to 23,500.

1950s and 60s: After WWII, there became a greater concern for safety when operating forklifts. To make loads more stable, backrests were added.  Overhead guards became a standard to protect operators from falling loads.

1980s to now: Further safety measures have been and are continuing to be standardized in forklift manufacturing: seatbelts, horns, back-up alarms, strobe lights, blue lights, etc. One of the biggest and ongoing improvements is power sources. Today’s forklifts operate on diesel, liquid propane, and batteries. Not only does this mean a wider selection to fit a manufacturer’s needs, but greater fuel efficiency. These advancements also make forklifts more environmentally friendly due to lower fuel emissions.

The forklift has come a long way since its birth in 1917 and continues to adapt to our every production need. With a wide array of models, capacities, and capabilities, there is a piece of equipment that fits almost every application. Not sure what you need?

Mashing Misconceptions About Used Forklifts

When trying to decide on a new forklift for your operation, you’re certainly going to look for the most bang for your buck. The words “Used” or “Pre-owned” can make a lot of buyers leery, but just take a deep breath while we squash some of the common qualms that people have about buying a used forklift:

1. A used lift is a subpar lift. There is one big reason that the word “subpar” shouldn’t be used when discussing pre-owned forklifts. Most used equipment is thoroughly evaluated when the dealer brings it on to their premises. To keep a strong reputation, a used equipment dealer needs to know what it will take to make a used forklift a quality forklift. This means combing over every spec of a piece of equipment. When you buy a used forklift from a reputable dealer, they will most likely tell you the history of the truck, the application it came from, and the issues it had when they evaluated it—not to mention what they did to make sure those issues no longer exist.

2. Used forklifts are forever plagued with issues. One of the biggest concerns when buying a used lift is that you might end up purchasing some problems along with it. As mentioned above, used dealers put their equipment through the evaluation wringer. However, sometimes you can still be uneasy. If that’s the case, ask the dealer to see the forklift in person. To help put your mind at ease, most used dealers offer some form of a warranty (usually 30-60 days).

3. Used forklifts depreciate quickly. Just like a car fresh off the line, a new forklift tends to depreciate faster than a used unit. A used unit—a retired rental unit that’s at least two years old, for example—has done much of its depreciating over the time it spent on rent.  So, buying a used forklift means you get the most value out of the equipment for the price that you paid.

Forklift Mast: Terms and Types You Need to Know

The mast, or upright, is the vertical assembly that raises the load that is being carried by your forklift. Essentially, it does quite a bit of the work. That’s why it is important to know mast terms and types. When the time comes to discuss your mast needs, you’re prepared. 

Mast Specifications:

      1. Overall Height Lowered (OAHL or OAL) is the distance from the floor to the top of the mast when the rails are completely down. If you aren’t sure whether your forklift will fit through your door, check the OAHL.
      2. Maximum Fork Height (MFH) is the distance from the floor to the top of your forks when the mast is fully extended. It is this measurement that tells you how high your product can be stacked.
      3. Overall Height Raised (OAHR) is the distance from the floor to the top of your carriage when the mast is completely extended.
      4. Free Lift is the height the carriage of you lift can move without the OAL increasing. Knowing this is an advantage when working in small spaces such as trailers. If your lift has full free lift, it can rise to the top of the OAL without raising the inner rails of the mast.

Mast Types:

      1. A single-stage mast only has one “channel” (or one set of rails) and a limited lift height.
      2. A two-stage mast (or a simplex) has limited free lift (usually 4’-6’) and is used for lower lift heights.
      3. A three-stage mast is the most common mast type. This mast has three sections that extend to maximum height.
      4. A quad mast has four sets of rails that raise your carriage and load.

The Advantages and Disadvantages of New, Used, or Wholesale Forklifts: Which Suits Your Needs?

Buying a forklift for your facility is a big purchase no matter what size operation you are running. So, when it comes time to cut the check, it’s good to know that you have the equipment that will work best for you and get you the most profit out of your investment. Below we have put together the advantages and disadvantages of New, Used, and Wholesale forklifts to help you figure out what you need:

New forklifts are the best option when you know the equipment will be putting in the work. New units are best for HEAVY USE- 4 hours or more a day.

      • They are brand new from the factory and built to order.
      • You can have the ruck built to your specifications
      • They come with a standard warranty (usually 2 years or 2,000 hours). This makes the cost of ownership lower because maintenance is covered for an extended period of time.

There are two disadvantages to new units:

      • The cost of a new unit can cause sticker shock for a buyer who won’t be using the forklift constantly.
      • When purchasing a new unit, there is always the possibility that you will have a long lead time. Because the truck is built upon purchase, it can take up to months to get it.

Used forklifts work best for operators who need to run the truck less than 3 hours a day, or only a few times a week.

      • The biggest advantage up front for buying a used forklift is the lower cost.
      • There is also the almost immediate availability. There may still be some lead time, but odds are it will be weeks compared to the months you can wait for a new unit.
      • Even though the forklift is a few years old, it will often still come with a warranty—usually 30, 60, or 90 days.

The disadvantages of used lifts:

      • The seller won't always know the previous application/maintenance of the machine. Sometimes, there is no background information on how the machine was treated before the seller obtained it.
      • A shorter warranty means higher maintenance costs. While you may catch a break on the initial cost, you won’t have the longer factory warranty to keep up on the cost of repairs.

Wholesale forklifts are the number one option for facilities that only need to pick up heavy loads occasionally.

      • The obvious benefit—lowest initial buy-in. Wholesale units are “as-is.” They may not be the prettiest, but they are at the right price for someone who doesn’t need to operate a forklift every day.
      • Out of the three, these units will have the shortest lead time. With most sellers, once they receive payment, the forklift is yours.

The disadvantages of a wholesale forklift:

      • There is no warranty.
      • Whole units are higher-hour, older units, which means that a higher maintenance cost is inevitable.

Each buying stage in a forklift’s life offers advantages and disadvantages to a buyer. While the disadvantages might be hard to stomach at first, it is important to consider which works best for your needs.

Understanding Your Forklift Data Plate

What is a forklift data plate?

A forklift data plate is provided on every truck, new or used, to let you and your operators know the vital information for running your forklift the moment you take a seat. Today, we are going to run through the information on your data plate and make sure you’re using your lift as optimally as possible.

What do all of these categories mean?

  • MODEL: The model number is one of the most important pieces of information on your data plate. You use this number to discuss needs with dealers, getting technical assistance, etc. It tells you and others the basics of your lift. For example, a Mitsubishi Model No. FGC25N will tell you the following:

FG- LP (liquid propane)

C- Cushion tires

25- 5000LB capacity (25x2x100)

  • SERIAL NO: While model numbers will tell you the capacity, tire type, and fuel type, these are basic components for any forklift. The serial number is specific to your forklift, so it will help a tech know what has been done to your machine in the past and let them familiarize themselves with the unit when you need service.
  • MAST TYPE: There are various mast types including simplex, 2-stage, and 3-stage. Mast types vary from model and application, so understanding your data plate helps you know the specific mast for that forklift.
  • FUEL TYPE: This shows you what your lift operates on: electricity (E or 24V/36V/48V), liquid propane (LP), diesel (DS), or compressed natural gas (CNG).
  • BACK TILT: This number tells an operator how far back a mast can tilt to keep loads securely on forks.
  • ATTACHMENTS: This section of your data plate lets you know what attachments have been added to your forklift. For example, your lift might be fitted with a side shifter, which is the most common attachment. 
  • FRONT TREAD: This number is the equivalent of the overall width of the forklift. This number helps operators determine the space a machine will take up in the warehouse.
  • TIRE SIZE: This spec tells you the tire size and type. If your plate says “solid” your truck requires solid pneumatic tires. If it says “smooth” or “treaded,” it is referring to the type of cushion tire. It is important to always replace the tires with the same size and type. They are specific to the truck.
  • TRUCK WEIGHT: This number tells you the gross vehicle weight of the unit, or how much the forklift weighs.
  • FORKLIFT DIAGRAM: This diagram tells operator important points for operating your lift with a load safely:

The horizontal load center.

The vertical load center.

The maximum fork height.

The distance the forks can be offset from the centerline (shifted left or right).

Knowing how to read a forklift data plate is not only important when using it, but when looking for a piece of equipment that fits your needs. If you are looking to replace your unit with the same model or one that might even fit your operations better, our experienced sales team at Greyson Equipment can help you.

Advantages of Side Shifts and Fork Positioners

Forklifts are an essential and beneficial part of any warehouse. They make moving heavy product easier and quicker, thus improving productivity across the board. While any lift truck is helpful, the attachments that you install on your equipment can make it even more so. Today, we will discuss the side shift and fork positioner and how these attachments improve safety and productivity in the workplace.

The two most common attachments that deal with Fork positioning are Side-shifters and fork positioners. Whether you have one or both attachments, your lift becomes more versatile.

What is a side-shifter?

A side-shift fork positioner, or “side-shifter” for short, is an attachment that allows the operator to shift the load being carried either left or right within a given span. 

What is a fork positioner?

A fork positioner is an attachment that is fitted to the load backrest of your forklift. It has hydraulic cylinders that attach to the tines of the truck so that the forks can be moved in an out by use of a lever.

The advantages of having one or both:

  • Loads can be moved and aligned in tight spaces. Instead of having to move your entire lift when the load your carrying isn’t quite centered, a side-shift allow you to move the load while in its intended space. 
  • Easily align forks with pallets. With the ability to make fork position more precise, there is less damage done to your forks, your pallets, and your product.  Both the side shift and pork positioner make it easier to place forks where they are needed without repositioning the entire lift.
  • Operators can remain seated. At first, it might not seem like your driver manually moving forks is time consuming but eliminating the need for your operator to dismount to move forks actually increases productivity. Aside from that, fork positioners help to make the floor safer for employees. The less feet you have on the floor, the less chance for accidents.

Making your equipment as versatile as possible will help you in the long run. Installing a side shift, fork positioner, or both is a surefire way to make it easier to use your forklift in varying situations.  When the time comes to consider what equipment will speed up your workflow, let our experienced sales team at Greyson Equipment answer any questions you have and get you off to a strong start.

It's Heavier than You think-Be Sure to Know Your Forklift Capacity

Knowing your forklift capacity might seem simple enough--you bought a 5,000lb capacity truck, so it should be able to carry 5,000lbs no matter what, right? But, there are a few factors that can affect the load capacity of your truck. Not knowing how attachments, lift height, etc. can affect your truck's capacity can lead to accidents in the workplace. To help you avoid issues, here are some need-to-knows when it comes to your forklift's load capacity:

Load Capacity

A forklift’s load capacity is defined as the weight that a forklift can safely carry.  It is important not to exceed this load so that you continue to operate equipment safely. However, there are other factors that affect the load capacity of your lift—for example, what you are carrying and how you carry that material.

Data plates and Load Centers

The best source for this information is your lift’s load capacity data plate. The load capacity plate, or “data plate,” tells you the load that a forklift can safely lift and even accounts for tilt in mast and specific attachments.  This is your most trusted resource for knowing what your truck can carry. The data plate tells you the forklift load center, or the balance point where your load is evenly centered on your forks and the load against the carriage of the lift.  The closer to the end of your forks you place the center of your load, the less weight your lift can carry. When you don’t know the load center of your forklift, you run the risk of tipping your truck over and causing a serious accident.


Attachments can also affect the capacity of your truck. So, it’s important to know if and how your attachment does this.  Any attachment you use should come with its own rated capacities and de-rated capacities (the capacity after the attachment is fitted). Try out this calculator to see how your attachment affects your forklift.

Mast Height

Mast height also has an effect on capacity. Forklifts with a high mast height will have two different load capacities. One for a low height and one for “carrying height,” or the capacity the truck is capable of handling with a raised mast.  

Even with these helpful hints, load capacity can still be tricky to understand. Knowing exactly what size of truck and capacity you need will ensure that your employees stay safe in the workplace.

How to Find Your Forklift Carriage Class

When you’re using your forklift every day, the part of your lift that is probably going to take the brunt of your work is your forks. They get scraped along the floor, ran into walls, wedged in pallet slats--among other hair-brained situations. That being said, when it comes time to replace your bent up and chipped forks, do you know what class you need? Or how to figure it out?

First things first, what part of the lift do you actually need to measure? Forks are ordered by carriage class. The carriage on your lift is comprised of the two bars that hold your forks on (indicated below by the red “A” line). It does not include the load back rest, or “gate,” that runs around the outside of the carriage.

Once you’ve determined which two bars make up the carriage on your lift, you need to measure the distance between the top of your upper carriage bar and your lower carriage bar (Also indicated by the red “A” line above). The measurement here can be used to identify the carriage class. Below is a chart to help you identify the classes:

Mounting Class

Carriage Height

Truck Capacity

















Now, while you may know the capacity of your forklift—which is also indicated in the chart above—always measure before ordering forks. Different manufacturers, applications, etc. may have various reasons for fitting a larger carriage on equipment. By measuring your carriage, you make sure that you know your carriage class.

If you're still not sure if you've got the carriage info down, or you have other questions before ordering forks, other attachments, or maybe even a piece of handling equipment, we can help you. Just contact Greyson Equipment here to get started. 




7 Tips for Keeping Your Warehouse Clean

Productivity is optimal when the environment your work is being done in is as efficient as possible. One of the best ways to keep your operations efficient is by keeping your warehouse clean. Here are seven tips to help keep your facility clean: 

  1. Create a schedule. One of the most important parts of keeping you warehouse clean is making sure it gets done every day. Creating a schedule—whether by shift or by individual employees—will help to make sure that the necessary everyday chores get done.
  2. Create a checklist. Along with a regular schedule of when to clean, it is important that employees understand what needs done. By creating a checklist of daily (weekly, etc.) maintenance and clean-up, you create expectations and a feeling of value in the workplace.
  3. Assign cleaning areas. Making workers responsible for certain areas of the warehouse—especially those they work in everyday—helps keep the whole warehouse spiffed up because when employees take care of their areas it makes their jobs smoother.
  4. Clean as you go. Spills happen. Even tiny ones should be taken care of right away. When workers take care of an issue right away—even just a small mess—they keep it from becoming a large problem and make a safer work environment.
  5. Keep bins around and emptied regularly. Along with keeping your supplies handy, having plenty of waste or recycling bins makes it easier to keep larger debris and unneeded waste off of the floor and out of the way.
  6. Keep supplies in stock. Staying on top of tasks is hard when you don’t have the tools to help you out. Making sure that you always have enough cleaning supplies to
  7. Reduce. Reuse. Recycle. Simple to implement and easy to reap the benefit.  Look for places to reduce unneeded clutter. Before throwing materials away (such as wooden pallets) consider how they might be reused or repurposed. Recycle any unwanted or unneeded materials such as cardboards or shrink wrap. Implementing a recycling program not only helps to keep your warehouse clean, but shows employees (and other businesses) that you go beyond the product and consider the larger picture as a company.

Once you've got your warehouse spick and span, using the right equipment when handling yo
