Zusammenfassung:Longitudinally spaced pairs of lateral guides are mounted on the relatively fixed section of a telescopic crane boom adjacent to the solid bottom chord of the movable section of the boom. The lateral guides are constrained against movement with the movable boom section by key or holder elements and the guides are adjustable laterally to establish an initial running clearance and are subsequently adjustable to compensate for wear. The guides are easily replaceable when necessary.
