Abstract

Compensating device for cranes for cantilevered telescopic arrows, consisting of at least one foot whose rear end is attached to the top of a mast and a mobile part capable of sliding longitudinally in relation to the foot, a retaining strap holding the arrow deployed and characterized because the. Strain cable, of constant length, is fixed by one of its ends to a pointer fixed to the mast, passing first this cable through a first pulley fixed to the front end of the arrowhead, then by a second pulley located in the rear of this same point, while the other end of the cable tie is fixed to the front end of the arrow foot, allowing this arrangement to have an arrowhead compressed under the effect of the non-tractor stringer, so that, which is be the telescopic movement of the arrow, the variation of the length of the strap between the pointer and the tip of the arrowhead is compensated with a cable recovery substantially equal to this variation caused by the telescopic action of the moving part in relation to the fixed part, an independent device being provided to ensure the telescopic action of the arrow and, the displacement of a car for the distrib ution of charges.
