Abstract

A hoist, a hoisting apparatus with said hoist and a method for securing a hoist. A hoist body having a drive mechanism for raising or lowering a hoist chain or a hoist cable is suspended from a support device by a hoist support. A safety device having a loosely arranged coupling element and a damping element is mounted between the hoist body and the support device. If the hoist support is released, the hoist body can drop by a drop height until the coupling element becomes taut. The damping element then damps the fall under the load of the hoist body, the hoist chain and whatever load is suspended from it.
