TRAVELING BODY SYSTEM

WIPO Patent Application WO/2019/008965

A1

In a local cart travel system (101), a first metal rail (11A) and a second metal rail (11B) are arranged parallel to each other in a second track (9). A voltage application device (81) applies an alternating-current voltage to the rails. A local cart (5) includes: a travel motor (45); a first power reception tire (63) and a second power reception tire (65); and a power reception device (91). The first power reception tire (63) and the second power reception tire (65) are each constituted by a solid tire in which an outer circumferential surface of a wheel (69) is covered by a solid elastic body layer (68). The first power reception tire (63) and the second power reception tire (65) respectively contact the rails, and thereby, the first metal rail (11A) and the first power reception tire (63) form a first capacitor, and the second metal rail (11B) and the second power reception tire (65) form a second capacitor. The power reception device (91) extracts an alternating-current power from the capacitors via the wheels (69), rectifies the extracted alternating-current power, and supplies the same to the travel motor (45).
