The primary object of the invention is to provide a telescoping hydraulic hoist (10) which is significantly lighter than hoists of similar types. The telescopic hydraulic hoist (10) is made of drawn-over-manual (DOM) aluminum tubing consisting of a specially formulated alloy. The hoist is fast-acting, has a greater bearing life, and air breathers (94, 96, 98, 100, 102) for the spaces between hydraulic stages, to prevent dirt from being sucked into the hydraulic mechanism.
Cette invention a pour objet principal un vérin hydraulique télescopique (10), qui est considérablement plus léger que les vérins de types similaires. Ce vérin hydraulique télescopique (10) est fabriqué en tubage d'aluminium étiré sur manuel (DOM), composé d'un alliage spécialement formulé. Ce vérin se caractérise par un action rapide, par une plus longue durée de vie des paliers et par des éléments (94, 96, 98, 100, 102) de ventilation de l'air, pour les espaces compris entre les étages hydrauliques, pour empêcher que la saleté ne soit aspirée dans le mécanisme hydraulique.
