ABSTRACT:
The load or the working platform is suspended and displaced by at least a pair of cables whereof the stresses are equivalent. Advantageously, each pair of cables is controlled by an emergency braking device comprising means for detecting the slack strand on one of the cables of the pair and controlling a braking on the other cable of the pair. So as to avoid an impact during the emergency braking, the working platform is also equipped with a shock absorbing device.
