A load test is performed to verify that a specific crane or hoist will safely perform all of its functions while supporting a test load whose weight is at least equal to the equipment's rated capacity. Because load tests confirm the ability of the crane and hoist to safely operate as intended, they must be completed whenever this overhead lifting equipment is newly installed, altered, repaired, or modified before being placed into service. Existing crane and hoist systems should likewise be load tested at a minimum of once in 6 Months & 1 year. The test load must be at least 100% and no more than 125% of the device's rated capacity.
