The invention relates to a drivetrain having a safety coupling (1) between two coupling parts (2, 3) of the drivetrain which are to be interconnected, in which drivetrain one of the two coupling parts (2, 3) is the drive part and the other coupling part is the output part, wherein the drive part can be connected to the output part via a safety element (4), the safety element (4) connected to the output part comprises a housing (5) having a bore (6) which is open towards the drive part, in which bore a pressure pin (7) and a coupling ball (8), which abuts the end face of the pressure pin, are axially movably guided and preloaded towards the drive part by means of a spring force, the drive part comprises a form-fitting engagement region (9) for the coupling ball (8), and the end region (25) of the pressure pin (7) remote from the coupling ball (8) projects out of the housing (5), at least in the uncoupled state, so as to be freely accessible. The safety coupling is intended to be self-restoring. This is achieved by: a centring flange (15) which is arranged on the drive part and projects beyond the output part; a retaining pin (18), which extends in parallel with the pressure pin (7) and is fastened to the centring flange (15); an actuating lever (21) which is pivotable transversely to the longitudinal axis of the pressure pin (7) and is arranged on the retaining pin (18); the actuating lever (21) has a wide end area (31) at its actuating end (30) and an oblique area (32; 33) starting from this wide end area.

The active motor locking assembly is utilized instead of at least one passive operating brake.
An overload protection device for cable lines, and in particular in cranes, is provided, having at least one electronic overload safety means. The overload protection device is provided to prevent any kind of damage which can be caused by an overload. That is achieved by providing a mechanical or magnetic overload protection device (1) in addition to the electronic overload safety means. The overload protection device (1) is integrated into the cable line or arranged at the cable fixing point and responds when a permissible cable tension force is exceeded and implements a cable extension.
