A working machine includes a pipeline disposed along a side deck in a front-back direction and connecting a hydraulic pump and a control valve. The hydraulic pump is mounted at a back portion of an upper frame of an upper rotating body and the control valve is mounted at a front portion of the upper frame. In the working machine, a reinforcing member having a space for accommodating the pipeline is mounted in the front-back direction of the side deck to an outermost side of the side deck in a widthwise direction thereof. The pipeline is passed through the reinforcing member.

Working machine

A construction machine including a maneuvering seat on which an operator sits, a guard cover for supporting the maneuvering seat thereon, and a control box arranged on one side of the maneuvering seat. The control box having a control valve and an operating lever for operating the control valve. The control box turning about a turning fulcrum so as to facilitate getting on and off when an operator gets on and off from the maneuvering seat. The construction machine further including hydraulic hoses which hang from the control valve and are pulled out of the control box. The hydraulic hoses having bent portions externally of the control box, the bent portions being displaced when the control box turns to absorb the up and down movement of the hydraulic hoses. Accordingly, the up and down movement of the hydraulic hoses caused when the control box is forced up is absorbed by bent portions provided externally of the control box.
