Hoisting gear |
摘要 |
The lifting gear includes a rotatably mounted drum (5) for winding up tension means (4), which is driven in rotation by at least one rotary driving device (19) comprising a rotary driving motor (21) acting on the drum (5) through at least one change-speed gearbox (25). The at least one rotary driving device (19) is-in relation to the axis of rotation (S) of the drum (5)-arranged alongside the drum (5) in such a way that the drum (5) and the rotary driving device (19) at least partially overlap in a projection perpendicular to the axis of rotation (S) of the drum (5).
