Upon completion of repair to a chain hoist, it must be static overload tested at 3000 pounds (1,362 kg).
Suspend hoist chain extended. Raise load approximately 12 inches.
Hold suspended test load by using hoist brake, for a period of 10 minutes.
Evidence of failure or permanent deformation of hoist parts shall be cause for rejection of static overload
test.
Perform dynamic overload test by loading hoist to 3,750 pounds (1,730 kg) then, hoist and lower the
load.
With test load clear of ground, operate in each direction, a minimal length of 1 foot of load chain.
Perform at a minimum hand speed of 10 feet per minute (ft/min).
Evidence of failure, permanent deformation or excessive wear of hoist parts shall be cause for rejection
of dynamic overload test.
Test hoist efficiency by loading hoist to 1500 pounds, then raise and load through any conveniently
measured distance.
