LIFTPAND

All the chain blocks and lever hoists bodies will have a dynamic load test here, then at least 1.1 times overload test before packages.

Every cooper motor of electric hoist or electric winch will be tested 5 times overload 1.25 times. Then let the motor rotate without load to check its performance.

All the electric chain hoists must pass 1.25 times static test and 1.1 times dynamic load test based on the rated lifting capacity.
