Abstract

Improvements introduced in tower cranes, of the type that involve a mast or tower whose upper part is articulated with a distribution boom and counter-jib which, respectively, extend towards the front and back of the mast axis, characterized by the upper beams of the boom and of the counter-jib constitute an uninterrupted rolling path for a carriage provided with a hoisting rope whose trajectory defines two lateral gears arranged on either side of the crane structure, so that when the carriage is moved to along the upper part of the boom, and after the counterjib, equipped with retention devices, the lateral lifting gear moves from one side to the other of the head of the mast, passing from the front to the rear of the axle of the mast or vice versa.
