Abstract

A winch including a casing for accommodating an electric motor, a gearbox and a roller for winding and unwinding a traction member. In order to provide a cost-effective flat winch which can be transported by a single person and used universally, in particular for the domestic sector, the casing has a box-like configuration to exhibit a shape and size of a suitcase or attache case, with the casing having opposite flat outer sides, with one outer side having attached thereon a suspension member, and the other outer side being formed with an opening for passage of the traction member. The electric motor, the gearbox and the roller are arranged in the casing and extend in a common plane, with the casing including a handle to allow transport of the winch by a person. The electric motor may be designed as a universal motor, and connected via a belt drive to the gearbox which is designed as a self-locking worm drive.
