摘要 PCT No. PCT/DK88/00029 Sec. 371 Date Oct. 20, 1988 Sec. 102(e) Date Oct. 20, 1988 PCT Filed Feb. 18, 1988 PCT Pub. No. WO88/06206 PCT Pub. Date Aug. 25, 1988.In overhead rail systems with branching tracks, a carrier such as a feeding container can be brought to pass a cyclic transportation course when the pertaining switches are correctly operated. By the invention the carrier (8, 6) and the switches (10) are arranged in such a manner that a predestined transportation course is automatically achieved without applying any separate control of the switches, as the carrier (6) is provided with switchable activation cams (22), which can co-operate with change-over switch arms (26, 28) on each rail switch (10) in such a manner that the carrier (6) by its own movement can cause a change-over of the switch (10), when this is relevant, as the activation cams (22) selectively are made operative and inoperative, respectively, by passing strategically placed, fixed actuator members (30, 32). Hereby a cyclic course of the conveyance of the carrier can be arranged purely mechanically.
