Abstract

Ballasting system for adjustable cranes, of which they have a device for retaining the boom, comprising a retaining cable arranged in the form of a hoist and controlled from a winch integral with the turntable of the crane, characterized by the fact of using ballasting means comprising: a fixed, vertical element, connected at its lower part to the rotating platform; a mobile element, capable of telescopically moving inside the fixed element; a rig or hoist, interspersed along the retaining cable, extended between the boom and the control winch, a first set of pulleys being supported by the upper part of the element capable of telescopically moving; and latching and lifting devices that equip the upper part of this mobile element.
