Abstract
A sorting equipment comprising a plurality of running trucks which travel in a coupled condition with one another along a definite travelling route comprised of a pair of rails. Disposed in each of the running trucks is a conveyor for conveying load laterally relative to a running direction. Induction lines are laid for supplying a high-frequency current along the travelling rails and a pickup coil is disposed in the running truck in an opposed relation to the induction lines. Rollers provided to each running truck which are to be brought into contact with the travelling rails are comprised of electrically conductive wheels, and the travelling rails are made of an electrically conductive material. In each running truck, a linear motor is disposed above the travelling rails and a metal plate is disposed on the linear motor. The metal plate is connected to an earthling conductor wired in the running truck, and the earthling conductor is connected to the rollers.
