Abstract

A crane assembly includes a main body, a boom extending from the main body, a cable, and a hook coupled to an end of the boom opposite to the main body by the cable, where the crane assembly is configured for lifting items via the hook. The crane assembly further includes a projection extending outward from the boom and curving toward the main body. The projection is configured to receive the hook over an end of the projection such that tension in the cable maintains the hook in place on the projection. Gravity is sufficient to release the hook from the projection when the boom is raised and the tension in the cable is released.
