ABSTRACT:
A tensioning device for the cable of a winch or hoist transmits rotational power from the drum, on which the cable is wound through a gear train to a traction roller which rubs against the cable as it passes into and out of the hoist. The gears rotate the traction roller in the same direction in which the cable is moving but at a speed which will always keep the cable under tension on the drum. Two overrunning clutches in the gear train transmit the rotary motion of the drum to the traction reel in either the cable payout or reel in operation.
