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.

摘要： A hydraulic drive device for a construction machine which can reliably judge whether or not the state of the construction machine is appropriate for stopping an engine is provided. The hydraulic drive device includes: a main pump 13; a regulator 15 that controls the discharge rate of the main pump 13 by a control pressure Pc; an engine 16 that drives the main pump 13; an engine stopping unit 83 that stops the engine 16 when a predetermined state of the construction machine has continued for a predetermined period of time; and a pressure sensor 72 that detects the control pressure Pc. The engine stopping unit 83 has a control signal judging unit 81 that judges whether or not the control pressure Pc detected by the pressure sensor 72 is lower than a predetermined pressure value Pc1, as a judgment of whether or not the predetermined state of the construction machine is present. The engine stopping unit 83 stops the engine 16 when a judgment result that the control pressure Pc is lower than the predetermined pressure value Pc1 is obtained. The predetermined pressure value Pc1 is a pressure value for controlling the discharge rate of the main pump 13 to the lower limit for use in the construction machine.
