description PURPOSE:To improve the working efficiency so as to reduce the fuel consumption by providing a pump selector valve in the intermediate between a hydraulic circuit for a tilt cylinder and a lift cylinder and a hydraulic circuit for a percussion device and selecting the valve in accordance with an engine rotational condition. CONSTITUTION:A pump selector valve 13 is provided in the intermediate between a hydraulic circuit 10, in which a tilt cylinder 3 and a lift cylinder 5 are connected to an oil hydraulic pump 9 of large capacity, and a hydraulic circuit 12 in which a percussion device 8 is connected to an oil hydraulic pump 11 of small capacity. A connecting condition of the tilt cylinder 3, lift cylinder 5 and the percussion device 8 to both the oil hydraulic pumps 9, 11 can be selected in accordance with the rotational condition of an engine. Further as necessary, selection of the pump selector valve 13 is automatically controlled by a shoe slip detection signal.
