Forklift Capacity Calculator

Understanding safe load truck capacity requirements can be difficult. Not only do you have to worry about ever-shifting OSHA regulations, but the various modifications that take place over the life of your forklift equipment will also come into play. Having access to the most up-to-date regulations is essential, if you are going to maintain acceptable capacities for the use of your truck. OSHA provides many of these requirements on their website, as well as mailing them out to those who request them. The following pieces of information will help you ensure that use of your truck stays within mandated regulations.

Be wary of the following potential hazards when it comes to safe load truck capacity:

Be aware of potential tip-overs when arranging your load. With too much weight on the forks, you can easily tip the truck forward, losing steering control when the back wheels lose contact with the ground. This could lead to a collision, or the load could fall from the fork lift.

Make sure you don't exceed the capacity of the forklift as printed on the nameplate.

Make sure that the data plate or nameplate stays up to date. Attempting to do so with manual calculations is not only time consuming, but prone to human error. Instead, use a tool, such as that located at where you can get approval from a registered professional engineer. This tool maintains up-to-date specifications as provided by the manufacturer, as well as an easy to use interface for adding custom modifications and attachments.

Minimize the distance between the load center and the front wheels. This will avoid potential tip-overs.

Ensure safe load truck capacity when moving multiple loads by positioning smaller loads closest to the front wheels. Do not put larger loads behind smaller loads during transport.

Be extra cautious when moving oversized loads. Laying them flat can result in load center that cannot be balanced on the fork, resulting in a tip-over or losing the load off of the forks.

Never attempt to transport a load that exceeds the stated capacity of the truck, as indicated by the nameplate or data plate.

When transporting a load close to the maximum allowable capacity, be extra careful of tip-overs, losing the load, and the danger of striking a passerby with a falling load. If possible, reduce the size of the load before transporting, if it is close to the maximum stated capacity.

Be sure to regularly compensate for wear on the forks, as this alters the safe load truck capacity.

When moving an oversized load, be extra careful to turn slowly to avoid shifting the center of balance. This, in turn, will minimize the likelihood of spilling a load or tipping the forklift.

Make sure to always wear proper safety gear when transporting a load.

Update the data plate regularly to accommodate changes in the equipment, including wear on the forks and modifications to the truck. Using a tool such as that provided at can make the process easier, eliminate errors introduced by manual calculations and allow you to obtain an OSHA compliant data plate from a professional engineer. This calculator also maintains up-to-date information provided by manufacturers that is useful in calculating safe load truck capacity.
