Abstract
A working vehicle has an upper rotating body and a lower traveling body. The lower traveling body is provided with: a center frame on which a swivel joint is vertically mounted; a right side frame on which a right traveling motor is mounted; a left side frame on which a left traveling motor is mounted; at least one right restriction member and at least one left restriction member, which restrict the maximum width of the vehicle; a right hose guide section having a right opening into which a right hydraulic hose is inserted, and provided to the right restriction member; and a left hose guide section having a left opening into which a left hydraulic hose is inserted, and provided to the left restriction member.
Claims19
A working vehicle comprising:
- an upper rotating body;
- and
- a lower traveling body that rotatably supports the upper rotating body,
- the lower traveling body including:
- a center frame on which a swivel joint is vertically disposed, one end of a right hydraulic hose and one end of a left hydraulic hose being connected to the swivel joint;
- a right side frame and a left side frame symmetrically disposed on sides of the center frame, a right traveling motor being mounted on the right side frame, the other end of the right hydraulic hose being connected to the right traveling motor, a left traveling motor being mounted on the left side frame, the other end of the left hydraulic hose being connected to the left traveling motor;
- at least one right restriction member and at least one left restriction member restricting a gap between the right side frame and the left side frame to be a maximum vehicle width, the right restriction member extending from the right side frame toward the left side frame and one end of the right restriction member, the left restriction member extending from the left side frame toward the right side frame and one end of the left restriction member;
- a right hose guide portion extending from the one end of the right restriction member towards the left side frame, the right hose guide portion having a right opening through which the right hydraulic hose is passed;
- and
- a left hose guide portion extending from the one end of the left restriction member towards the right side frame, the left hose guide portion having a left opening through which the left hydraulic hose is passed.
A working vehicle comprising:
- a hydraulic hose;
- an upper rotating body;
- and
- a lower traveling body that rotatably supports the upper rotating body, the lower traveling body including:
- a frame on which a swivel joint is vertically disposed, wherein a first end of the hydraulic hose is connected to the swivel joint;
- a side frame disposed on a side of the frame, wherein a first traveling motor is mounted on the side frame, and wherein a second end of the hydraulic hose is connected to the first traveling motor;
- a restriction member configured to prevent a width between the side frame and the frame from exceeding a maximum width, the restriction member extending from the side frame and toward one end of the restriction member;
- and
- a hose guide portion extending from the one end of the restriction member and away from the side frame, wherein the hose guide portion defines an opening through which the hydraulic hose extends.
