Transport system

The system comprises a main track 2 and a branch track 3 connected at a branch point, a first power supply line 12 provided along the main track 2 and a second power supply line 13 provided along the branch track 3, a transport vehicle 4 for moving along the track and having attached thereto a driving unit for moving it along the track, a route selector for selecting a route at the branch point, and a power receiver for receiving electric power from the power supply lines and supplying it to the drive unit. As shown, (fig 3, not shown), the vehicle 4 is steered by mechanism (30) comprising a motor (31), gears (32, 33) and link (34) for turning shaft (38). In another embodiment, (figs 5, not shown), the tracks have magnetic guide rails (47, 48) and a magnetic guide roller (42) on arm (43), which may be selectively swung from one side to the other to either guide rail (47, 48). In fig 8 (not shown), the vehicle has vertically movable route-selecting rollers (210A, 210B) for engagement with guide rails (203A, 203B).
