Abstract

PROBLEM TO BE SOLVED: To cut installation cost by improving a feeding device in various kinds of transportation machines which transport materials only at given positions on the rails. SOLUTION: Feeding parts 19 are provided at given positions Q only on the rails 1. With a carrier runner 2 pausing at one of the given positions Q on the traveling rails 1, the collecting part 20 of the carrier runner 2 contacts the corresponding feeding part 19 to make it possible to feed power to the hoisting electric motor of a motorized lift. An indicating lamp is lit when the carrier runner 2 is halted at the given position Q on the rails 1, which enables an operator to be easily made known of the state that power can be fed. Because the installing area of the feeding parts 19 is reduced, it is possible to cut the cost in transportation machines on which the motorized lift is used at a given position Q only on the rails 1. Furthermore, it is possible to make the carrier runner 2 stop reliably at a given position Q on the rails 1.
