Abstract

The hoist mechanism is particularly for a tower crane with crab, having an upper and a lower hoist block (4, 5) suspended by rope (6) from the crane jib (2). Upper and lower blocks, crab and jib are equipped with guides, also means for hooking into engagement, and stops and controls are provided for coupling up resilient or pivoting components. The upper and lower blocks are locked into engagement and released automatically. The crab can have a piston-type guide, mounted vertically and thrust upwards by a spring. There is a horizontal plate on the lower part of the guide, acting against the tops of components pivoting on the upper hoist block. These deflect the bloc and release it from the lower one.
