IV. APPENDIX:
See how to calculate to choose the forklift truck and the proper
distance from forklift as below
:
Forklift truck’s Load
Capacity Specs.
Rated Load
Capacity(tons)
Method:
-
Choose a forklift truck in according to
the user’s demands.
-
To prevent the forklift truck overturning, the
user must calculate to ensure Moment a of the
forklift truck greater than Moment of the stone
loading creates
(
