ABSTRACT:
A cable pulling device includes an anti-reversing clutch between the driving means and capstan to allow the capstan to be rotated by the motor in one direction for cable pulling but preventing rotation of the capstan in the reverse direction by cable loads when driving motor power is interrupted. The anti-reversing clutch prevents breakage of the drive chains and other drive train components.
