摘要

The safety arrangement for a crane hook is designed to automatically release the load from the hook on deposition on the ground. Elimination of manual operation of crane hook increases safety at work and prevents injuries. The safety mechanism consists of a lever pivoted in the region of the hook (1) tip. The lever is loaded by a retraction spring (5) and it has a stop. This lever ejects the hook load as soon as the load has been deposited on the required location and while the load exerts no force on the hook and the lever (3).
