Abstract
A concrete bridge deck finishing machine for bridge deck construction and repairs comprises an elongated, horizontally extending box frame in the general form of a parallelepiped, which is elevated above a deck or roadway to be finished by a plurality of vertically upright, adjustable jack stands that are propelled hydraulically to traverse roadway surfaces, travel rails or forms. A reciprocating carriage suspended from the frame controls a downwardly suspended finishing head apparatus that contacts the concrete surface below for striking off, densifying and/or finishing. The carriage transversely moves back and forth in response to hydraulic circuitry actuated by a plunger driven ramp that separately controls the rate of machine propulsion, carriage traversing speed, carriage deceleration, and the direction of carriage travel. Carriage travel and reversing is synchronized with proper roadway travel commands from mechanically triggered hydraulic valves.
