  • Control system for actuating drill pipe rack
    Patent number: 10392878
    Abstract: A control system for actuating a drill pipe rack is provided. The drill pipe rack moves between a first position and a second position. The control system includes a first actuator to actuate a top end of the drill pipe rack and a second actuator to actuate a bottom end of the drill pipe rack. The control system includes a pump to supply pressurized fluid to the first actuator and the second actuator. The control system further includes at least one volumetric flow divider in fluid communication with the pump. The volumetric flow divider is configured to supply equal volumetric quantity of the pressurized fluid to the first actuator and the second actuator, and subsequently move the drill pipe rack between the first position and the second position.
