Cable braking and backward tension device

摘要

A cable braking and backward tension device (14) for providing a braking and backward pulling force to a cable (4) comprising a stand (2), a spool (3) rotatably attached to the stand (2), the spool (3) being adapted for the cable (4) to be wound on it, a braking disk (5) with a plurality of permanent magnets (7) attached to it, the braking disk (5) being rotatably attached to the stand (2), an actuator (6) coupled to the braking disk (5) and configured to rotate the braking disk (5), wherein the braking disk (5) is located coaxially with a spool (3) and wherein the spool (3) is made of ferromagnetic or paramagnetic material.
