A flexible means 1 passing in detour over a differential wheel 58 suspended by a shaft 40 has an automatic loading system 43 in a frame, has its two ends forced to pass between wheels, detour guides 7 for rolling up with the aid of its fastener 2 fixed through a slot in the rim of a disc or cam, with a smooth periphery or with a groove 3, supported by its shaft 17 having a ribbed or smooth end, in a framework 15, which assembly is hung on a post 87 on polyplanar rollers by the flexible means 1 passing through a wheel 25 pivoting in detour in a pulley block and detour wheels 504-55 integral with a tensioning slide 54. Tensioning and adjustment are achieved with a tie 30 attached behind the tensioning slide 54, this tie is connected to a winch 48 supported by the framework 15 containing the traction means 3. A casing 8 coupled via its extended shaft 5. The ribbed or smooth shaft 6 can turn epicycloidally about the ribbed or smooth shaft 5, fixed by the action at the top of the disc or cam 3 of the mass hung through the flexible means 1. The orthogonal position is indexed by pin 12 through the framework 15 which is itself fixed to the post 87 after adjustment by pin. A ribbed means 432 with pin, passing in the shafts 17, 5 and 6, couples with lever 433 and slide 589 on the shafts 17, 5, 6, making it possible, by a rotation, to restore, regardless of the action or direction of rotation which has given rise to it, a positive effort with the flexible means 1 in traction in the top position. <IMAGE>
