Abstract
A device for ascending along a rope comprises a pair of ascenders and a leg loop in the form of a pedal cooperating with a cord passing over two pulleys to form a tackle device authorizing a gearing down effect of the effort exerted on the leg loop. The effort required for an ascending step corresponds to two thirds of the weight of the climber, whereas the leg travel when moving from the standing position to the sitting position is about one and a half times the distance of an ascending step.
