APPARATUS FOR LAYING TRACK

摘要

A track laying car has a rear undercarriage for moving the car in a working direction on the track rails and track-laying bogie for selective engagement with the ballast bed for moving the car on the ballast bed in the absence of a track for the rear undercarriage. An endless scraper conveyor chain is vertically adjustably mounted on the car and includes a transverse stringer arranged for engagement with the ballast bed for planing the ballast bed and conveying excess ballast from the planed bed, the stringer being arranged in front of the bogie. A tie conveyor is mounted on the car to convey ties in a direction opposite to the working direction to the planed ballast bed behind the bogie and to lay the conveyed ties sequentially on the planed ballast bed, and a ballast conveyor moves in a path arranged to enable the ballast conveyor to receive the excess ballast and to convey it in a direction opposite to the working direction to the rear end of the car where the ties have been laid on the planed ballast bed.
