A perfected telescopic boom for hydraulic cranes, characterized because. On the outer surface of the inner end of the telescopic intermediate section, a double support is supported, which in its front part houses a horizontal plane pulley. In the upper rear part of this support there is a housing for anti-friction metal plates, whose mission is the of absorption of the friction produced by the displacement in the mobile section inside the fixed outer shell the anti-friction plates are mounted on metal plates having, on their underside, a bulged part being housed in a support cavity. The oscillation that this arrangement allows the plates of antifriction material, causes the friction surface to adapt to the irregularities of the inner surface of the fixed outer envelope part of the pen.
