Provided is a working machine including a console box restrained from wobble. The working machine includes a machine body having an operator's seat and a console box at a side of the operator's seat. The console box includes a box body and a box cover covering the box body. The box cover internally includes a first cover half installed on the box body with first fitting portions and a second cover half internally including second fitting portions fitted with the respective first fitting portions. The second cover half abuts on the first cover half and coupled to the first cover half by respective interfittings of the first and second fitting portions. The box body includes a support portion making contact with an inner surface of the second cover half to support the second cover half.

Working machine

A seat stand includes a seat support section including an installation plate portion having an upper surface on which a seat is provided and an left control box support section extending from a seat support section to the left side of the seat and supporting a left control box. The left control box support section includes an extension portion extending sideward from the installation plate portion and including an upper surface on which the left control box is supported. A arranging space is provided under the extension portion in such a manner that a connection line extending from the left control box supported on the extension portion is arranged through the arranging space. A cutout portion, formed in the extension portion, penetrates the extension portion in a vertical direction and is open sideward.

Seat stand and working machine including same

Provided is a construction machine where a pilot hose is easily routed. The construction machine includes a seat stand, an operator's seat provided on the seat stand, a remote control valve provided just above a front end of the seat stand at least one of right and left sides of the operator's seat; a hydraulic valve; and a pilot hose interconnecting the remote control valve and the hydraulic valve. The seat stand has an upper surface including a specific surface located beneath the remote control valve and a reference surface on which the operator's seat is installed. A step is provided between the specific surface and the reference surface to make the specific surface be lower than the reference surface, thus enlarging a space for routing the pilot hose beneath the remote control valve.

Construction machine with pilot hoses

A left support pillar includes a protective portion extending substantially vertically in front of a back rest of the operator seat so as to cover an operator seat sideways, a fixing portion fixed onto a rotating frame at a position behind the operator seat, and a connecting portion adapted to extend forward from the fixing portion and to be connected to a lower end of the protective portion. The protective portion is disposed within a predetermined range of a seating surface of the operator seat and is formed upward from a position lower than an upper end of the back rest.

In a construction machine having a working attachment, an operator's seat disposed on one side of a machine body, a devices receptacle portion disposed on the other side, and an operating member disposed sideways of the seat for operating the attachment, the machine is characterized in that a canopy comprises a front support post disposed in front of the seat, a rear support post disposed behind the seat, a side support post disposed sideways of the seat and on the side where an operator gets on and off the machine body, and a roof which connects the support posts with one another, the front support post being disposed close to the devices receptacle portion and the side support post being disposed outside the operating member to form an open portion obliquely in front of the seat where open portion is for ensuring a working vision for the attachment which is swung to the seat side.
