Abstract

A telescopic extension device for cranes and the like, whose telescopic mast is constituted by a fixed lower element that supports an upper element sliding which in turn has a stroke and a counter-arm characterized in that the extension is secured with a cable single fixed at one end to a fixed base and passing successively around a pulley arranged at the rear end of the counter-arm, around a rotating organ, then around a pulley placed at the top of the lower element and, finally, around a set of pulleys located at the base of the upper element before being crossed by its other end to the upper part of the lower element.
