摘要： 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.

摘要： The invention relates to a drive device (1) for the spool (6) of a winch. The drive device (1) comprises a drive motor (2) having a drive shaft (5), a transmission (3) and an output shaft (4) that drives a spool (6). The transmission has a first drive connection (10) between the drive shaft (5) of the drive motor (2) and the output shaft (4) to the spool (6). The first drive connection (10) drives the output shaft (4) over a first rotational speed range (DB1) in a first gear. According to the invention, a second drive connection (30) is provided between the drive motor (2) and the output shaft (4), wherein the second drive connection (30) drives the output shaft (4) over a second rotational speed range (DB2) in a second gear. The second drive connection (30) is designed to be separate from the first drive connection (10) as a parallel drive path, and is driven by the drive motor (2) together with the first drive connection (10). If the output shaft (4) is driven by the second drive connection (30), the power flow of the first drive connection (10) from the drive shaft (5) to the output shaft (4) is interrupted.

摘要： Embodiments of the present disclosure disclose a drive for an electric clutch if a winch. The drive comprises a pusher block having a first end, a second end, and a transmission component arranged on a central portion of the pusher block to drive a transmission shaft; a first driving unit connected to the first end to drive the first end to reciprocate between a first position and a second position; and a second driving unit connected to the second end to drive the second end to reciprocate between a third position and a fourth position. The drive enables switching of the transmission shaft between a high speed mode, a low speed mode, and an idle mode. A winch including the drive is also disclosed.

摘要： A drive train for a rescue hoist includes a first stage, a second stage, and a third stage. The first stage receives an input from a motor and the third stage provides rotational power to a cable drum. The first stage, second stage, and third stage are disposed coaxially within a common housing. The first stage provides a first speed reduction, the second stage provides a second speed reduction, and the third stage provides a third speed reduction between the motor and the cable drum. The common housing includes a mounting flange for mounting the drive train to the rescue hoist.
