Abstract

Improvements in the construction of lifting devices and telescopic crane operation, characterized in that the actuation is carried out by means of a motor-lathe, and simultaneously a telescopic drive cable, a tilt cable and another cable for lifting the arrow, causing the elevation of the outer mast, the telescopic ascent of the inner mast and the elevation of the arrow of a single reach, joining a rear sling the pendolºn of the arrow with the chassis and supporting the efforts of load of the arrow, forming the cable of elevation of the arrow and the sling polipastos to obtain greater progressivity of the movements and to prevent its brutal completion.
