Abstract: A vehicle supports a first roller conveyor having stop members at opposite sides of the vehicle mounted for pivotal movement between the rollers of the first conveyor to assist in stacking ties on the first conveyor from either side of the vehicle. The first conveyor feeds stacks of ties into a horizontal compression means and a vertical compression and banding means for banding stacks of ties. A second roller conveyor feeds banded stacks of ties away from the banding means. Dump arms at opposite sides of the vehicle are mounted for pivotal movement between the rollers of the second conveyor to dump banded stacks of ties to either side of the vehicle. Hydraulic motors drive the conveyors, and a sensor is provided adjacent the second conveyor to sense the position of a stack of ties, the operation of the hydraulic motors being responsive to the sensor.
