CLS-920i Installation Manual 3
1.2 Considerations Before Installation
While the CLS-920i Cargo Lift Scale will fit most typical forklifts, there are certain considerations that must be
taken into account prior to installing the scale. Due to the extra weight of the CLS-920i, the net lifting capacity of
the forklift is decreased by approximately 10%. Use the following formula below, to calculate the net capacity of
the unit.
NOTE: Formulas can give you a good estimate of how capacity will be affected. But you should work closely with your
forklift manufacturer before making a decision. Their data reflects, in most cases, testing with specific forklifts and
attachments.
Net Capacity = A(B + C) - D (E + F)
E + G + H
Where:
A = Truck basic capacity in pounds
B = Inches from the front wheel center line to fork face
C = Inches from fork face to truck rating point (usually 24")
D = Weight of the scale in pounds ( 428 lbs )
E = Inches from the front wheel center line to the carriage face
F = Inches from the carriage face to scale Horizontal Center of Gravity (HCG)
G = J + K (inches from the carriage face to rear face of load
H = Inches from fork face to new truck rating point
J = Thickness of fork
K = Thickness of scale
CAUTION
Another consideration is the indicator power source will be connected directly to the battery of the
forklift. Most typical is 12 volts for propane, gas and diesel forklifts. However, some diesel forklifts are 24
volts.
The CLS Series Cargo Lift scale will not operate on a positive ground forklift. Verify the forklift has a
negative ground electrical system. Refer to the forklift users manual to further verify grounding
requirements.
1.2.1 CLS Classes and ID Plates
During the initial sale or installation of the CLS-920i, you need to remind your customer that they must have an ID
plate on their forklift updated stating the new lifting capacity and center of gravity information. This requirement is
per OSHA rules and regulations.
