Strike-off beam and spreader plow assembly for placer/spreader
First Claim
1. A method of transporting a placer/spreader including a frame carrying a conveyor for supplying material to be placed onto a substrate to be paved, the conveyor being movable relative to the frame between a retracted position in which the conveyor is substantially disposed beneath the frame and an extended position in which the conveyor extends laterally from the frame, a strike-off beam extending parallel to and removably attached to the frame, and a spreader plow arrangement connected with the frame and including a spreader plow car with a spreader plow blade laterally movable substantially parallel to the frame and the strike-off beam, the spreader plow having a width less than a spacing between the frame and the strike-off beam so that the spreader plow car with plow blade can reciprocate in a lateral direction for spreading the material onto the substrate during operation of the placer/spreader, the method comprising moving the strike-off beam and the spreader plow arrangement towards each other in a direction generally transverse to the strike-off beam to positions proximate to each other so that a part of the spreader plow arrangement overlies the strike-off beam, loading the frame with the conveyor in its retracted position onto a transport vehicle, nesting the spreader plow arrangement and the strike-off beam transport vehicle while in the positions proximate to each other and adjacent the frame, and with the transporting vehicle moving the frame with the retracted conveyor and the nested strike-off beam and the spreader plow arrangement to a different location.

Abstract
In combination with a placers/spreader having a frame including at least two side bolsters standing parallel to the subgrade path and at least two cross beams spanning the subgrade path forming a conveyor supporting structure. A rail system is attached spanning the frame, and has a roll in/roll out conveyor with a cantilevered support at one of the side bolsters and a support for attachment to and support from the rail system. The conveyor moves in traversing motion across the frame to distribute concrete. The improvement comprises a strike off beam and spreader plow assembly for trailing attachment to the frame of a placer/spreader. We thus disclose a strike off beam with spreader plow assembly which can be removably attached to either side of a placer/spreader to avoid the necessity of relocating the receiving conveyor when the location of the access road changes from one side to the other or direction of spreading changes. We additionally disclose a method of operation the strike off beam from a placer/spreader to prevent the accumulation of excess concrete the path of the following paver.
