PROPER OPERATION

BASIC LOAD CENTER AND RATED LOAD
CAUTION
•
When traveling with loads, keep the forks 15 to 20 cm (6
to 18 in.) above the ground surface and keep the mast
tilted back fully.
•
The allowable load of a truck equipped with an
attachment is reduced in comparison with that of the
standard truck.
If the truck is equipped with a load-handling means such as a
hinged fork, load grab, or rotating clamp, its allowable load will
be reduced as compared with that of the standard truck (a truck
without any attachment) for the following reasons:
Never exceed the allowable load indicated on the load chart
attached onto the truck or attachment.
Reasons for a reduction in the allowable load:
1) The weight of an attachment is added.
2) The attachment shifts the basic load center position forward,
and thus the allowable load is reduced.
The basic load center is the distance from the front face of the
forks to the load’s center of gravity. The chart given above shows
the relationship between the basic load center and the weight of
loads to be allowable for the 20-ton truck. This chart is called a
load chart and is attached to the truck.
