Disclosed is a system for the storage and traction of a cable, in particular a synthetic cable fitted to an offshore crane. The storage/traction system includes a frame that carries in particular a storage device including a support carrying a storage reel through an assembly defining an axis of rotation. Between the storage reel and the support, the assembly includes of a single slewing ring including two rings that are free to rotate with respect to each other: —a fixed ring that is fastened to the support; and —a moving ring that is, on the one hand, fastened to the storage reel and, on the other hand, rotated by a motorization.

Disclosed are a winch, a rope guide, and a transmission device having a clutch function. The winch includes a base seat, a reel, a rope guide, a transmission assembly, and a motor. The reel is rotatably provided to the base seat. The rope guide is provided to the base seat. The transmission assembly is connected with the rope guide. The motor is connected with the reel to drive the reel to rotate, and the motor drives the rope guide through the transmission assembly. In the winch according to embodiments of the present disclosure, the rope guide is an active rope guide, bringing about a good rope guiding effect. Moreover, the reel and the rope guide are driven by the same motor, which reduces the number of components and parts, simplifies the structure and control, and lowers costs.

A cable winch (100) for deploying and retracting a cable (50) during the installation of powerline cables on transmission towers. The cable winch (100) includes a base frame (102), a spool (110), a drive system (120), a sensor system (200), and a control system (300). The spool (110) is mounted for rotation on the base frame (102) and the cable (50) is releasably securable to the spool (110). The drive system (120) is able to drive rotation of the spool (110) to either pay out or wind in the cable (50) along a cable path. The cable path passes through the sensor system (200), which has a first sensor (244) able to detect and output tension data in relation to the tension in the cable (50) passing through the sensor system (200). The control system (300) is adapted to receive the tension data output by the sensor system (200) and modulate the speed and torque of the drive system (120) in order to maintain a predetermined tension in the cable (50).

A portable winch and method of use is shown. One advantage of winches shown includes an ability to lower a boom or boom sections into limited access exit pit for winching operations such as pipe bursting. Sectional boom designs shown provide the ability to easily raise and lower a boom large distances without the need for a single long boom. Selected winch designs shown include flexible inserts between the boom and the winch frame that help resist damage from unforeseen shifting of the device during operation. Designs and methods shown also include multiple pulleys on a boom end unit. Fasteners are shown that reduce build up of debris.
