CA 2514339

A climbing aid, for assisting a worker in climbing a ladder. A counter weight is provided, positioned through means of a rotating pulley assembly, a counter arrest system, and a cable system, in-part, help pull the climber up the ladder. The climber's weight is redistributed to allow the climbing aid to carry approximately 50% of the climber's original weight and will allow him to climb a ladder less strenuously. In this manner the climber must only exert the amount of effort required to carry the remaining 50 % of their weight. The redistribution of weight allows a climber to work for longer periods of time without tiring. The climbing aid is not an elevator but, rather, allows the climber to have full control of his ascent and descent at any and all times. The climbing aid greatly reduces the strain on climbers and will result in a safer working environment for service people.

L'invention concerne un accessoire d'escalade destiné à aider un ouvrier à escalader une échelle. Un contrepoids est prévu, lequel est positionné au moyen d'un ensemble poulie rotative, un contre-système d'arrêt et un système de câbles qui contribuent en partie à faire monter l'échelle à l'escaladeur. Le poids de l'escaladeur est redistribué afin de permettre à l'accessoire d'escalade de porter approximativement 50 % du poids de départ de l'escaladeur et lui permet d'escalader une échelle moins difficilement. Ainsi, l'escaladeur peut exercer uniquement la quantité d'effort nécessaire à porter les 50 % restant de son poids. La redistribution du poids permet à un escaladeur de travailler pendant des périodes plus longues sans se fatiguer. L'accessoire d'escalade n'est pas un élévateur, cependant il permet à l'escaladeur d'avoir une pleine maîtrise de son ascension et de sa descente à tout moment. L'accessoire d'escalade réduit considérablement l'effort des escaladeurs et il a pour effet de procurer un environnement de travail plus sûr au personnel de maintenance.
