A vane motor with a rotor body driven by compressed air having vane gaps for radially movable vanes and a rotor shaft for rotatably bearing the rotor body relative to a motor bushing. A method for lubricating a vane motor that ensures particularly long, low-service operation is provided. The rotor shaft is configured as a hollow shaft with a first lubricant reservoir in the interior. The first lubricant reservoir has a lubricant filling opening accessible from the outside of the vane motor. The first lubricant reservoir is connected by at least one radial lubricant hole to at least one further lubricant reservoir arranged in a section of the rotor body between two vane gaps, and/or is connected to an outlet opening arranged in one of the vane gaps for supplying lubricant into the vane gap.

Vane motor

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.
