摘要

Improvements in the construction of transportable cranes by road, characterized in that the crane is constituted by: a boom or tower, articulated to the base body and fixed in a more or less inclined position by a connecting rod; an arm, articulated at the other end of the boom and having its curved stock, on which a cable is supported and fixed, coupled at its other end to a hoist; a lever, articulated at one end to the base body and in the other supports a stack of counterweights; and a cable, connected on one side to a point on the arm stock, and on the other side to the support of the counterweights.
