Abstract

A compact hoist with a central hoist housing and an enclosed transmission located opposite a motor. The output shaft, of the motor, is guided coaxially through a transmission output shaft that is hollow and supports a sprocket wheel, or similar device, and receives power from the transmission. The hoist is particularly easy and economical to assemble, service and repair, and is flexible when in use. In a preferred embodiment, the motor shaft is mounted in a transmission cover opposite the motor and the transmission-output shaft is mounted, on one side in the wall of the hoist housing, and on the other side in an end plate of the motor. That configuration makes the invention particularly suitable for automatic assembly.
