Abstract
A railway tie plate insertion vehicle includes operator's chairs mounted on both sides of the vehicle; with the occupants of each chair being provided with a tie plate insertion wand including controls for movement of the vehicle. A tie magazine deposits a tie plate on the tie upon actuation by the operator when a tie plate has not been previously deposited. A first rail clamp includes a pair of rollers for engaging the rail, attached to the ends of a pair of scissor arms, so that raising the rail draws the scissor arms closer together, increasing the gripping pressure on the rail. A similar rail clamp is located at the rear of the vehicle, which also includes an electrical connection for the operator's wand, thereby permitting tie plate insertion from the rear of the vehicle when obstacles are present along the sides of the vehicle.
