Transport device, e.g. lifting device, has movable load-carrying part, bus bar with position code carrier, read head for code carrier that can read out absolute position for movable part from code

摘要

The device has a load-carrying part movable along a fixed path with at least one electrical load, a bus bar extending along the path of movement with at least one current-carrying slip conductor and a contact device for the slip conductor on the movable part. The bus bar has a position code carrier along the movement path. The movable part carries a read head for the code carrier that can read out an absolute movable part position from the code. The device has a load-carrying part (2) movable along a fixed path, at least one electrical load on the movable part, a bus bar (5) extending along the path of movement with at least one current-carrying slip conductor and a contact device for the slip conductor on the movable part. The bus bar has a position code carrier along the movement path and the movable part carries a read head (19) that interacts with the code carrier and can read out an absolute position for the movable part from the code
