Abstract:
The invention relates to a crawler for transporting loads, having at least two chain drive units (12a, 12b) and a bearing unit (16) on a chassis (14) between the chain drive units (12a, 12b), to a system comprising a plurality of crawlers of this type and to a method for transporting loads. In order to provide a crawler, and a system and a method, by means of which very large loads can be transported simply and exactly in a controllable manner, the bearing unit has a load pickup (20) for a load to be transported, and has a hoist cylinder (18) having a piston (19) for adjusting the height of the load pickup (20). The hoist cylinder and the piston (19) are mounted to the bearing unit (16) in a rotationally locked manner, wherein the load pickup (20) is coupled to the hoist cylinder (18) by way of a ball and socket connection (22, 24) such that a rotational and swivel movement between the load pickup (20) and the bearing unit (16) is possible, and that a rotary sensor (27) is provided in order to determine an angle of rotation between the load pickup (20) and the piston (19) or the hoist cylinder (18).
