Lift Heavy Stuff - Accident Documentation: Load escape from hoist hook
Channel: Technology Rediscovery
Date: 03/01/2021

During a hoist operation to move three commercial-grade, solid-core wood doors into the second level wood shop, the main hoist hook was improperly loaded with sideways force, causing its ballast and block to rotate about 90 degrees clockwise. The weight of the primary load slid from the rated body of the hook to the non-rated clip made from light-weight sheet metal. This, of course, could not sustain the 200lb weight of the primary load and the closure failed. The load dropped about 8 vertical feet into the aluminum patio below, tearing the aluminum weld of about 12 feet of awning strip.
