Abstract

A working machine includes a vehicle body, a travel apparatus provided to a rear portion of the vehicle body, a fender provided above the travel apparatus, and hydraulic piping that is disposed between the travel apparatus and the fender and that extends from a front-portion side to a rear-portion side of the fender.

First claim

The invention claimed is:

1. A working machine, comprising:
a vehicle body;
a travel apparatus provided on a rear portion of the vehicle body;
a fender provided above the travel apparatus in a vertical direction of the working machine; and
hydraulic piping that is disposed between the travel apparatus and the fender, wherein a portion of the hydraulic piping is disposed below a lower terminal end of the fender,
wherein the hydraulic piping comprises a first hydraulic pipe and a second hydraulic pipe,
wherein the working machine further comprises:
a control valve that is provided on the rear portion of the vehicle body, wherein a rear-portion side of the first hydraulic pipe is connected to the control valve; and
a piping holder that is installed on the fender and comprises a holding portion that holds the second hydraulic pipe that is not connected to the control valve, and

wherein the control valve controls supply of a hydraulic fluid through the hydraulic piping.

2. The working machine according to claim 1 ,
wherein the hydraulic piping comprises a plurality of hydraulic pipes,
wherein the plurality of hydraulic pipes is disposed below the fender,
wherein the plurality of hydraulic pipes is lined up in a width direction of the vehicle body and is in higher positions at an outer side of the width direction.

3. The working machine according to claim 2 , further comprising:
a first bracket that is installed to the fender and supports the hydraulic piping below the fender.

4. The working machine according to claim 2 , further comprising:
a cabin provided to an upper portion of the vehicle body; and
a second bracket that is installed to a lower portion of the cabin and that supports the hydraulic piping in front of the fender and to a side of the cabin.

5. The working machine according to claim 2 , further comprising:
a front wheel provided on a front portion of the vehicle body;
a vehicle-body frame that supports the front wheel; and
a third bracket that is installed on the vehicle-body frame and that supports the hydraulic piping to a side of the vehicle-body frame.

6. The working machine according to claim 1 , further comprising:
a first bracket that is installed to the fender and supports the hydraulic piping below the fender.

7. The working machine according to claim 6 , further comprising:
a cabin provided to an upper portion of the vehicle body; and
a second bracket that is installed to a lower portion of the cabin and that supports the hydraulic piping in front of the fender and to a side of the cabin.

8. The working machine according to claim 6 , further comprising:
a front wheel provided on a front portion of the vehicle body;
a vehicle-body frame that supports the front wheel; and
a third bracket that is installed on the vehicle-body frame and that supports the hydraulic piping to a side of the vehicle-body frame.

9. The working machine according to claim 1 , further comprising:
a cabin provided to an upper portion of the vehicle body; and
a second bracket that is installed to a lower portion of the cabin and that supports the hydraulic piping in front of the fender and to a side of the cabin.

10. The working machine according to claim 9 , further comprising:
a front wheel provided on a front portion of the vehicle body;
a vehicle-body frame that supports the front wheel; and
a third bracket that is installed on the vehicle-body frame and that supports the hydraulic piping to a side of the vehicle-body frame.

11. The working machine according to claim 1 , further comprising:
a front wheel provided on a front portion of the vehicle body;
a vehicle-body frame that supports the front wheel; and
a third bracket that is installed on the vehicle-body frame and that supports the hydraulic piping to a side of the vehicle-body frame.

12. The working machine according to claim 11 , further comprising:
a hydraulic pump provided to the rear portion of the vehicle body,
wherein the hydraulic piping comprises a drain pipe that returns a hydraulic fluid to the hydraulic pump, and
wherein the third bracket comprises a drain support portion that supports the drain pipe.

13. The working machine according to claim 1 , wherein the hydraulic piping sends a hydraulic fluid to a front-mounted implement and returns the hydraulic fluid from the front-mounted implement.

14. The working machine according to claim 1 , wherein a portion of the hydraulic piping is disposed below a rear terminal end of the fender.
