A lifting hoist (10) having a powertrain (14) that includes a hysteresis clutch (23) for transmitting torque from a driving motor (15) to a transmission for moving a load pulling element (11). The hysteresis clutch (23) can be set to incur a slippage differing significantly from zero before a nominal load bearing capacity (FNom) of the hysteresis clutch is reached by the pulling element (11). Hence, when the lifting hoist operates within the range at or near the nominal load-bearing capacity (FNom), it is operable with continuous slip. The waste heat generated in the process is preferably transferred to the wall of the transmission housing via an oil bath, with the wall serving as a cooling surface. The lifting hoist can be built smaller and has improved operating properties.
