The maximum weight data placard on forklifts should never be regarded as the maximum amount able to be lifted. There are several factors that affect the lifting capacity, which is often reduced for various reasons. It is important to remember the lifting capacity is based upon the load center.


Did you know you lose weight-lifting capacity for every one inch beyond the actual load center? It is your responsibility to calculate the load center for any type of attachment used with the truck, including the original one. In addition, each time you switch attachments, it is essential to recalculate the load center and maximum load lift capacity of the forklift.


To learn more about the factors that affect the load center and load capacities, please feel free to continue reading the following infographic presented by Lift Truck Capacity Calculator. We can also provide assistance with determining the load center for a variety of attachments, as well as those that are worn by contacting us directly.

Driving a forklift or similar heavy lifting equipment is a responsibility not to be taken lightly—if handled improperly, these heavy mobile vehicles can cause serious damage both to the immediate environment and to human beings in their path.


To a large extent, safe operating procedures are a matter of simple common sense, but sometimes accidents happen even to experienced, mindful drivers. In a significant number of these incidents, the problem can be traced to a very simple cause: inaccurate capacity data labels.


Data labels are easy enough to ignore. Some forklift drivers rarely, if ever, glance at them, preferring instead to trust gut feelings developed through long experience. This is a mistake, however. It’s important to refer to these labels to ensure the maximal operating safety of lifting equipment—but this information is useless if it is out of date or just plain wrong.


Inaccurate data labels can cause multiple problems for you; let’s explore the issue further in the infographic posted below.

If your company uses a forklift, you know how important this piece of equipment can be. What you might not know is how versatile a forklift can be as well. Special forklift attachments can be used to help transform your forklift into a multi-purpose machine or designated for a very particular task.


Special forklift attachments are convenient. You can add rotators, barrel clamps, push-pull attachments, and more to help make your forklift meet your industry needs. If the attachments are not certified for your machine, however, there are hazards to using these attachments. OSHA guidelines help decide whether an attachment will affect the safe operation of your forklift. By utilizing a certified attachment (and forklift), you’re ensuring that your employees can safely operate the machine and get the job done.


If you’re interested in using special forklift attachments, continue reading the following infographic. You’ll learn more about OSHA’s requirements for these attachments, as well as how Professional Forklift Engineering Services can help you find the right attachment.

Stability when driving a forklift is essential so that your operators do not tip when moving a load from one place to another. There are certain design stability requirements set by the industry and manufacturers that are in place for each specific type of powered industrial truck. The term “design stability” refers to the measurement of a truck’s resistance to overturning under controlled circumstances. Here are a few factors that can influence stability:

  • Weight Distribution
  • Truck Speed
  • Wheelbase
  • Suspension Method
  • Wheel Tread

Taking these factors and more into account, forklifts and other industrial trucks are tested and inspected to determine stability. A tilting platform test verifies stability and can also be used to enhance forklift design to better meet the needs of operators and warehouses. Various test values are also calculated to forecast prevision and stability, followed by tests to confirm that weight distribution and other factors are adequately maintained.

Ensuring that you follow all safety standards and regulations in your warehouse is essential in order to maintain compliance and reduce the risk of injury to your employees. In addition to organizing storage spaces and improving workplace efficiency, understanding the standards set for powered trucks and forklifts will promote safety and increase accountability for your business. These govern everything from workplace lighting, to storage, to the color of paint on the vehicle. Here are just a few to become familiar with:

  • The USA Standard Safety Color Code for Marking Physical Hazards and Identification of Certain Equipment should be followed in relation to obstructions and aisles.
  • Areas designated for battery charging and installations should only be used for that purpose.
  • Ensure that the storage and handling of fuel, such as diesel and gasoline, are up to code.

Be sure that your management team and employees are aware of the various safety standards in place for the storage and operation of powered industrial trucks in order to avoid potential injury and loss for your organization.

Forklift safety is not to be taken lightly. This equipment is involved in around 90,000 accidents every year and sometimes people sustain sever, and occasionally even fatal injuries from these incidents. Even if a forklift accident at the workplace doesn’t result in such serious consequences, it’s likely that a business will find still itself embroiled in workers’ compensation issues, and OSHA will always investigate the accident looking for regulatory violations. The infographic depicts the various recorded causes of accidents.  Regardless of the ultimate resolution, a missing or incorrect data plate will be flagged, will result in OSHA fines and can be legal fodder.

An incorrect or missing data plate can preclude an operator and the management team from understanding the lifting limitations of the machine. Properly trained forklift operators understand how to read the data plate and look for the forklift’s maximum capacity in a particular situation. Fortunately there is now no reason to operate with an incorrect data plate because the specialists at Professional Forklift Engineering Services make it easy, quick and cost effective to stay OSHA compliant.

Understanding the lateral stability of a forklift is essential in order to ensure that operators complete jobs safely when using the equipment. The best way to think about lateral stability for a forklift is to compare it to your car. When you make this comparison, you can see that a forklift is narrower, higher up, and without suspension to handle bumps. Therefore, it is crucially important for an operator to practice safe driving techniques so the lift does not overturn.

Driving and turning at a reasonable speed, as well as exercising caution on slopes, will help maintain the center of balance for the forklift. That way, each job can be safely completed while eliminating the risk of dropping the load or crashing. Be sure to read all safety information when using a rotational attachment, and perform a thorough equipment check before operating the forklift, so that any potential risks can be assessed by management if needed.

If you operate directly or manage the use of forklifts in your warehouse, it is important to have all of the information possible about your machines so that you can maintain high levels of safety and reduce risk. To achieve this, forklifts are equipped with a nameplate, also called the data plate. The data plate includes vital information about the forklift, such as its fuel type, weight, and lift capacity. To ensure safe usage of your forklifts, it is necessary to have employees read the data plate thoroughly during training and before use. While the data plate has all of the information needed, it can be tough to decipher the meaning of each metric.

The data plate on a forklift is broken down into different sections, which each stand for a different characteristic and measurement. Some of these include:
• Mast and Back Tilt – Refers to the type of mast and the maximum degree of back tilt allowable.
• Tire Size – Ensures proper replacement tires are used to maintain levels of safety.
• Load Center – Gives a capacity based on how far forward from the mast the balancing point of the load is.

If any modifications are made to a forklift, or if it has an attachment, the data plate must be updated to reflect the new capacity. Similarly, if a data plate goes missing or is illegible, you are required to replace it. To do so, contact Professional Forklift Engineering Services at
