ABSTRACT:
A driverless transfer truck includes a chassis having two bogies for riding on rails. Each bogie is provided with at least one drive wheel which is pressed against a drive shaft so that the force for propelling the truck is produced by the friction engagement between the drive wheel and the drive shaft. By attaching the drive wheels to the bogies, the truck can negotiate a curved section of the rails having a smaller radius than is otherwise possible.
