Abstract

1414387 Constant tension winches FRANCE ARMED FORCES-MINISTER OF 10 Dec 1973 [11 Dec 1972] 57218/73 Heading B8B A constant tension winch comprises a winding drum 14 connected to a driving shaft by a first eddy-current coupling, and a cable guide pulley 51 connected to the winch frame by a second eddy-current coupling which controls the rotation of the pulley 51. The winding of the first coupling is supplied with constant current so that a constant tension is applied to the cable over a range of speed differences between the driving shaft and the drum. A cable distributing pulley 24 is carried by a nut 23 which engages a threaded shaft 8 rotated by a toothed wheel on the drum 14. A further pulley 44 is spring biased so as to urge the cable into engagement with the guide pulley 51.
