A swiveling work machine includes a traveling apparatus, a swivel base mounted on the traveling apparatus to be pivotable about a vertical axis, a hood disposed at a rear portion of the swivel base, the hood accommodating therein an engine, a support frame being disposed across over the engine, and a ROPS having a front end thereof fixed to the swivel base and a rear end thereof fixed to an upper portion of the support frame. The support frame includes a front leg member disposed on one lateral side of the ROPS, the front leg member extending to vicinity of a position forwardly of the swivel base.

Swiveling work machine

A swivel work machine includes a traveling unit, a swivel base plate supported on the traveling unit to be pivotable about a vertical swivel axis, the swivel base plate having a first lateral side and a second lateral side provided across said vertical axis, a pair of upper and lower support brackets disposed at a front end of the swivel base plate with an offset toward the first lateral side and adapted for supporting an implement, a pair of left and right vertical ribs extending rearward from the support brackets and fixed to the swivel base plate and a cabin mounted on the swivel base plate. The cabin is disposed with an offset toward the second lateral side relative to the support brackets, a bottom of the cabin being disposed downwardly of the upper support bracket. The vertical rib disposed on the side of the second lateral side extends, from its front portion to its intermediate portion, parallel with a side face of the cabin on the side of the first lateral side.

A swiveling work machine includes a swivel deck mounted to be pivotable about a vertical axis and a side cover for covering one lateral side on the swivel deck, an accommodating space capable of accommodating a work machine accessory being provided inside the lateral cover. The accommodating space accommodates, as the implement accessory, a work oil tank, a fuel tank and a control valve unit. The work oil tank is disposed at a fore-and-aft intermediate portion on one lateral side on the swivel deck. The fuel tank is disposed forwardly of the work oil tank with forming a gap relative thereto. The control valve unit is disposed upwardly of the fuel tank and longitudinally along the fore/aft direction.

Cabin for work machine

A work vehicle includes a cabin, a driver's seat provided in the cabin, a step disposed downwardly of the cabin for providing access for a driver to the driver's seat and an air conditioner for conditioning air inside the cabin, the air conditioner having an air conditioner body, an air inlet/outlet box, and a blower pipe for sending conditioned air from the air conditioner body to the air inlet/outlet box. The cabin includes an entrance door mounted to one lateral side thereof and includes the air inlet/outlet box mounted to the other lateral side thereof. The air conditioner body is disposed downwardly of the driver's seat and the blower pipe is disposed downwardly of the step.

Work vehicle

A backhoe ( ) includes an upper structure ( ) supported by a traveling device ( ) to be rotatable about a vertical swivel axis (X). The upper structure ( ) carries an excavator ( ) and a cab ( ) and has a rear edge ( A) formed arcuate about the swivel axis (X) in plan view. The cab ( ) defines an opening ( ) with a door ( ) attached through hinges ( ). The door ( ) is pivotable about a vertical open/close axis (Y) of hinges ( ). The hinges ( ) are arranged on a rear edge opening ( ). Each hinge ( ) includes a pair of hinges ( A and B) which are bent to place the axis (Y) forwardly of the rear end of door ( ). Consequently, when the door ( ) is set to a fully open position, the free end of door ( ) is displaced to a position forwardly of the rear edge ( A) of upper structure ( ).
