The present invention concerns a rope health monitoring system and a rope for such rope health monitoring system whereby the rope comprises objects which are remotely detectable, readable and programmable identification (ID) tags and whereby the rope monitoring system comprises said rope, at least one ID tag reader device mounted along said predetermined path of the rope, to detect at least the identity and optionally the historic health status and/or at least one physical rope parameters of the individual rope section provided with and identified by the at least one ID tag, at least one ID tag writing device, to write a new health status of the individual rope section to the at least one ID tag, at least one means to measure at least one rope operation parameter, a computing unit provided with data, whereby the computing unit is equipped with an algorithm capable to compute the relative longitudinal positioning of individual sections of the rope and the additional damage or damages suffered by individual sections of the rope, compute and record the new health status of the individual sections of the rope, store the new health status of the individual section of the rope in the corresponding programmable ID tag of the rope.

The present invention relates to a free-fall winch comprising a drum which can be rotatorily driven by a winch drive via a transmission and can be retained by a holding brake, wherein in addition to the holding brake a free-fall brake is provided for slowing down the drum in free-fall operation. According to the invention, the free-fall brake is arranged between winch drive and holding brake on the one hand and drum on the other hand such that when the free-fall brake is open, the drum is decoupled from the winch drive and from the holding brake and can be rotated at idle with respect to the winch drive and the holding brake.

A drive train is provided for hoisting gears, and in particular for hazardous transports. The drive train includes a drive motor (1), a cable drum (6) connected thereto, a reduction transmission (5) arranged between the drive motor (1) and the cable drum (6), a service brake (4) provided between the drive motor (1) and the reduction transmission (5) and a safety brake (7). To prevent damage to the reduction transmission (5) in the event of an emergency stop braking an automatic overrun disconnect means can be provided between the drive motor (1) and the service brake (4). The overrun disconnect means is preferably in the form of a freewheel (2).
