Abstract: An apron return assembly having a pump that is adapted to convey a fluid, an apron actuator having an apron actuator cap side and an apron actuator rod side and being in fluid communication with the pump, an accumulator that is in fluid communication with the apron actuator cap side, a reservoir that is in fluid communication with the apron actuator, and a tension rod having a frame end and an apron end. In the preferred apron return assembly, the apron actuator and the tension rod are adapted to move the apron between a closed position and an open position. A method for moving the apron from the open position to the closed position.

Abstract: An apron assembly comprising an apron mounted to the crusher and adapted to be moved between an operating position and an open position, a tension rod operatively attached to and disposed between the shock absorber mount and the apron, a spring seat mounted to the crusher and adapted to be moved between a raised position and a lowered position, a spring operatively disposed between the tension rod base and the spring seat, an actuator mounted to the crusher and the spring seat and adapted to be moved between a retracted position and an extended position, a shock absorber operatively attached to and disposed between the spring seat and a shock absorber mount. The shock absorber reduces the pressure applied to the actuator. A method for controlling the opening in a crusher comprising providing an apron assembly and moving the shock absorber between a retracted position and an extended position.
