A load compensating device (15) for a nuclear fuel element handling machine has : a frame (16) fitted to a fixed supporting structure (13); a slide (17), which runs along the frame (16) and is attached to a hoisting member (6) such as a cable; a first and second fluid-operated piston device (18a, 18b) connected mechanically in series to each other and to the slide (17); and an operating fluid feed circuit (19) for parallel-feeding operating fluid to the piston devices (18). The first piston device (18a) is designed to keep the tension of the hoisting member (6) above a given minimum value (T min ); and the second piston device (18b) is designed to keep the maximum tension of the hoisting member (6) below a given maximum value (T max ). |
