Abstract
Improvements to telescopic coupler crane jibs, with a pair of boom sections with telescopic inter-adjustment each, and having lateral frames or joints and frames in the upper and lower parts, and equipped with upper and lower pairs of wear dampers interposed between the upper wefts or joints of the boom sections and the lower wefts or joints thereof, characterized in that the wear dampers of the upper and lower pairs are located substantially and directly above and below said wefts or joints sides of the inner section of the boom, for the transmission of forces directly into it, and the corresponding lateral frames or joints function substantially as columns to absorb said forces; Mechanical means are available to retain the upper wear dampers on the inner boom section, and to retain the lower wear dampers on the outer boom section.
