Abstract

A hopper barge consists of two barge halves articulated to each other along a longitudinal axis of the barge. First and second cylinder-piston actuators are mounted in respective opposite ends of the barge and connected between the two barge halves. Respective first and second pressure fluid tanks are located adjacent each actuator. A pressure fluid pump is connected by a suction line to the first tank and by a pressure line to a three-position switching valve, and the first tank is connected by a return line to the three-position switching valve. The valve is selectively operable to connect these lines alternately to respective opposite ends of the cylinder of the first actuator. The second pressure fluid tank is connected to the second actuator by a suction line, and an interconnection line extends between the first and second tanks. A common pressure line interconnects corresponding ends of the cylinders at the actuators. A flow line interconnects the opposite ends of the cylinder of the second actuator and has a check valve therein, and a check valve is also provided in the common pressure line. The three-position switching valve has a first position, for opening the hopper barge when the latter is loaded, a second position, for closing an empty hopper barge, and a third position for opening the hopper barge when the latter is empty.
