Abstract: A hydraulic system associated with an ejector truck is configured to move an ejector plate and a rear gate. The hydraulic system may cause the rear gate to begin moving before the ejector plate. As well, the hydraulic system may reduce the delay in initiating the movement of the ejector plate and the rear gate, and increase the moving speed of both the ejector plate from the retracted position to the extended position and the rear gate from the closed position to the open position.

Abstract: A hydraulic control system for a machine, the machine having a service brake and a parking brake, includes a hydraulic fluid tank, a pump configured to withdraw hydraulic fluid from the hydraulic fluid tank, and a first accumulator and a second accumulator fluidly connected to the pump. The first and second accumulators configured to supply the hydraulic fluid to the service brake and the parking brake. Further, a resolver valve fluidly coupled between the first and second accumulators and configured to selectively supply the hydraulic fluid from one of the first and second accumulators to the parking brake.
