  • Self-adjusting slide block for telescopic crane jibs
    Publication number: 20060226107
    Abstract: A slide block for a telescopic crane jib includes at least two mutually co-operating and relatively movable slide block parts, at least one of the parts comprising an oblique surface. The parts of the block are pre-tensioned or biased to move in a direction so that the total width of the slide block will vary and enlarge to fill a gap between inner and outer telescopic jib sections. In a telescopic crane jib-slide block arrangement incorporating such a slide block, the slide block is disposed on an inner telescopic jib section and presents a sliding surface to an adjacent outer telescopic part.
