ABSTRACT:
A drive unit for a hoisting apparatus and, in particular, a passenger or freight elevator, has a supporting structure, a drive motor, a brake apparatus and a planet gear. The planet gear is driven by the drive motor and has a housing jacket which forms the drive stage and bears a pulley on its periphery. The planet gear is supported by the supporting structure on both sides of the pulley. As opposed to a one-sided support, this results in a favorable load distribution. The brake apparatus is provided on the driven portion of the planet gear.
