Claim:
1. Hybrid work equipment comprising: an electric actuator that is adapted to perform a forward-reverse movement; a control unit that is adapted to be operated by an operator in a forward direction or a reverse direction to drive the electric actuator; a pilot circuit that is connected with the control unit, the pilot circuit being configured to generate a forward pilot pressure or a reverse pilot pressure in accordance with the forward operation or the reverse operation of the control unit; and a control device configured to receive the forward pilot pressure and the reverse pilot pressure generated by the pilot circuit and to output a drive command to the electric actuator, the forward-reverse movement of the electric actuator being commanded by the drive command, wherein the control device comprises: a differential pressure acquiring unit that is configured to acquire a differential pressure between a pilot pressure of the pilot circuit corresponding to the operation direction of the control unit and a pilot pressure of the pilot circuit in a direction opposite to the operation direction; a control command generator that is configured to generate a control command to the electric actuator based on the differential pressure of the pilot circuit acquired by the differential pressure acquiring unit; and a drive controller that is configured to control a drive of the electric actuator based on the control command generated by the control command generator.
