TRAVELLING SLEEPER-LAYING MACHINE

摘要

A mobile track laying apparatus comprises an elevator on a vehicle movement along a right-of-way for lowering a succession of ties, a roller and gliding conveyor receiving the lowered ties and laying the ties on the ballast as the vehicle moves along the right-of-way in an operating direction, and a guide wheel power-driven to rotate about a horizontal axis extending transversely to the right-of-way, the guide wheel having a plurality of radially extending abutment and entrainment elements arranged to interdigitate between the successively lowered ties in an end region of the conveyors adjacent the ballast.
