Abstract

A warning device that is removably affixed to overhead loads which are moved by an overhead crane. The warning device has a rotating beacon light and a horn, both activated by a switch and powered by internal batteries. The device is attached to steel loads with magnets or to non-metallic loads with straps and is activated whenever the load is raised and in motion. The device is removed from the when the load arrives at its destination load and is then stored by attaching the device to the crane hook with a safety cable.

Claims
