1. An energy recovery system comprising:

  • a pump configured to provide pressurized fluid;

    a first fluid actuator having a first chamber and a second chamber and being configured to receive the pressurized fluid;

    a second fluid actuator having a third chamber and a fourth chamber and being configured to receive the pressurized fluid;

    a first valve fluidly connected between the pump and the first and second actuators;

    an isolation unit having a first selectively restrictable passageway fluidly connecting the first chamber, the third chamber, and a first outlet of the first valve, and a second selectively restrictable passageway fluidly connecting the second chamber, the fourth chamber, and a second outlet of the first valve; and

    an energy recovery unit in fluid communication with the isolation unit,wherein the isolation unit is configured to direct a flow of pressurized fluid from the second actuator to the energy recovery unit; and

    the energy recovery unit is configured to convert the flow of pressurized fluid to a first mechanical power output.
