    Proportional Control Hydraulic

    power units

    Proportional Control Hydraulic power units allow for complete braking control. The hydraulic system monitors signals from the master PLC and determines the braking mode from this data. The onboard integral PLC system constantly scans the brake system data and tests various logic conditions to determine that the system is operating within specified parameters. Johnson proportional control hydraulic power units also include manual control and over-ride, while interposing relays provide for bypass of the integral PLC system by the Master PLC. A highly reliable proportional control valve is used for precise brake control and gradual soft stopping, regardless of load conditions. All filters in the system are over-sized to extend replacement life and the hydraulic system utilizes a flow through design which ontinuously cleans the system oil every brake cycle
