A lift system defines a vertical hoist axis and includes a holding unit for lifting and lowering an object in a direction along the vertical hoist axis. An overload coupling mutually connects the drive shaft of a motor and the input shaft of a gear assembly. The overload coupling includes a latch mechanism having a motor latch part and a gear assembly latch part. The latch mechanism defines a latch characteristic providing a first transmittable torque in a lowering rotational direction and a second transmittable torque in a lifting rotational direction determined so as to cause the first transmittable torque to be less than the second transmittable torque. The latch mechanism includes a rotational positioning device configured to permit a latching of the motor latch part into the gear assembly latch part in only one possible relative rotational angle position within 360° referred to the lifting rotational direction.
