Considerations Before Installation

1.2.1

Forklift Derating

1.2.1.1 Capacity Reduction Calculation
The CLS fits most typical forklifts, but there are considerations that must be taken into account prior to installation. Due to the
extra weight of the CLS, the net lifting capacity of the forklift is reduced by approximately 10%. Use the formula below to
calculate the amount to down-rate the lifting capacity and determine the net capacity of the forklift.
A = Truck Basic Capacity in pounds
C = Inches from face to truck rating point (usually 24)
E = Inches from front wheel center line to carriage face
G = J + K (inches from carriage face to rear face of load H = Inches from fork face to new truck rating point
J = Thickness of fork
1.2.1.2 CLS Classes and ID Plates
An updated ID plate on the forklift stating the new lifting capacity and center of gravity information is required per OSHA rules
and regulations.
