Measure the distance from the back toeboard
to the center of gravity of the equipment
(distance A or distance B). This is the load
center. Refer to Illustration 1.

From these numbers, determine the total load
of your equipment on the platform.
Personnel lifting applications:
Subtract this
number from the maximum platform capacity
of the machine, as defined in the appropriate
machine operator's manual and decals, to
determine the remaining platform capacity.
Example:
Lighting equipment and the mounting
bracket used to attach it to the guard rail weigh
167 lbs/76 kgs. Their center of gravity (balance
point) is located at 35 in/0.8 m from the back toe-
board. Because the load is concentrated at the
front guard rail, its effect on capacity is greater
than a distributed load. The chart tells us that the
reduction in capacity is 234 lbs/106 kgs. On a
platform with a 500 lbs/227 kgs capacity, the
remaining capacity is 266 lbs (500-234=266) or
121 kgs (227-106=121).
