Hydraulic working machine

摘要

A hydraulic excavator includes a cab (13) disposed on a front portion of a revolving upper structure (1). An internal combustion engine (13) is mounted in a rear portion of the revolving upper structure, and a directional control valve (14) is disposed in the front portion of the revolving upper structure (1) at a position spaced laterally from the cab (3). The directional control valve (14) is arranged longitudinally of the revolving upper structure (1). A hydraulic oil tank (15) and a fuel tank (16) for the internal combustion engine (13) are disposed on either side of the directional control valve (14). By virtue of a space provided between the directional control valve (14) and the cab (3), transmission of heat and operation noise from the directional control valve to the cab is greatly suppressed. <IMAGE>
