Calculate estimated forklift capacity at a changed load center, solve allowable center or required rated capacity, and check load utilization in lb, kg, inches, millimeters, or centimeters.

Required: rated capacity, rated load center, and actual load center.

Use one capacity unit and one distance unit consistently.

Measure from the vertical fork face or attachment face to the load’s center of gravity.

Compares the planned load with the field-estimated adjusted capacity.

Reference estimate only. Never exceed the forklift data plate. Attachments, lift height, mast configuration, uneven loads, and operating conditions can reduce capacity; obtain an approved capacity rating or updated data plate from the manufacturer or qualified forklift professional.

Forklift Load Center Capacity Formula

The following equation is used to calculate the forklift load center capacity.

FLC = SLC / ALC * SRC
  • Where FLC is the load center capacity (lbs)
  • SLC is the standard load center distance (in)
  • ALC is the actual load center distance (in)
  • SRC is the standard rated capacity (lbs)

To calculate the forklift load center capacity, divide the standard load center by the actual load center, then multiply by the rated capacity.

What is a Forklift Load Center Capacity?

Definition:

A load center capacity describes the equivalent capacity a forklift can hold when the load center distance is different than the standard load center distance that the forklift was rated at.

How to Calculate Forklift Load Center Capacity?

Example Problem:

The following example outlines the steps and information needed to calculate Forklift Load Center Capacity.

First, determine the rated capacity. In this example, the rated capacity of the forklift is 7,500 lbs at standard load center.

Next, determine the standard load center distance. In this case, this is determined to be 20 inches.

Next, determine the actual load center distance. For this problem, the actual load center is 30 inches.

Finally, calculate the load center capacity using the formula above:

FLC = SLC / ALC * SRC

FLC = 20 / 30 * 7500

FLC = 5,000 lbs
