Patent Number: 051805413
Section: abstract

The device comprises two winches (12, 12') fastened to the outer surface of a hollow body (2) having a vertical channel (3) in which the load (4) is displaced. Each of the winches (12, 12') comprises two drums (13a, 13b) driven by a common motor (14). The drums (13a, 13b) of a first winch (12) are each arranged opposite a drum of the second winch (12') in relation to the axis of the channel (3). The device comprises two cables (15a, 15b) which are common to two drums located opposite one another around the body (2). The cables (15a, 15b) are wound with their end part on the drums located opposite one another and on their run between the drums pass over deflecting pulleys (16a, 16b), the axis of which is stationary, and over load-supporting pulleys (34a, 34b), the axis of which is movable and accompanies the load. The device ensures that the load is held and displaced in the event of a failure of one of the motor assemblies (14) and in the event of a break of one of the cables. The device can be used particularly for ensuring the lifting of a fuel assembly in a flask for handling the fuel assembly.
