摘要： A first hydraulic circuit leads, as clutch control pressure, pressurized oil supplied from a first hydraulic pump, to a transmission control device after regulating the pressurized oil, and leads, as torque converter operation oil, pressured oil to a torque converter, and leads pressurized oil to an oil cooler. Through a second hydraulic circuit, pressurized oil from a second hydraulic pump is distributed to a circuit portion downstream of the pressure regulation valve and upstream of a safety valve and to a circuit portion downstream of the torque converter and upstream of the oil cooler. A flow control device changes a proportion of a rate of flow in the second hydraulic circuit so that a proportion of the rate of flow to the circuit portion downstream of the torque converter and upstream of the oil cooler increases as pressure at an entrance of the torque converter increases.

摘要： A hydraulic steering unit 5 generates a control pressure corresponding to the rotational quantity and rotational direction of the steering wheel 109 on the basis of pressurized oil of a pilot pump 13. Signals of pressure sensors 6a and 6b used to detect the control pressure, and a signal of a front operation detection unit 31, are inputted into a controller 132. A controller 32 and solenoid valves 33a and 33b control a stroke of a steering valve 4 so that the stroke becomes larger with increase in control pressure detected by each of the pressure sensors 6a and 6b. In addition, when the operation of a front work device is detected, the controller 32 and the solenoid valves 33a and 33b control the stroke of the steering valve 4 so that the stroke becomes larger than that provided when the operation of the front work device is not detected.

摘要： On an upper revolving structure, an engine having an exhaust port is mounted. In the midway portion of the exhaust pipe connecting the exhaust port of the engine and an exhaust gas post-treatment device, a first bellows pipe and a second bellows pipe are arranged through a connecting pipe having an L-shaped bending portion. In this case, the first bellows pipe and the second bellows pipe are arranged so as to have a positional relationship in which axis lines thereof (X1-X1, Z1-Z1) cross each other. That is, the first bellows pipe is arranged in a horizontal direction so that its axis line (X1-X1) extends in the left-right direction of the upper revolving structure. The second bellows pipe is arranged so that its axis line (Z1-Z1) matches the vertical direction of the upper revolving structure.
