Abstract: An overhead travelling crane movable along a path of travel, and also from side to side along the path has fixed to it a depending boom or mast which carries a movable section which can be raised and lowered to pick up materiel from either side of the path by means of a fork-like device near the bottom of the movable section. In the usual arrangement there are two such masts provided with lifting forks spaced apart from each other along the path, such that the forks can lift the two ends of cylindrical or pipe-like objects having cylindrical or tubular end members which can be grasped by the two spaced forks. Objects thus lifted by the forks can be carried along the path to some other location. A guide means equipped with wheels and rollers provides ease of movement of the movable mast sections up and down the fixed mast section without binding even under eccentric loading.
