As a result, there is no need to prepare a complicated bracket or the like in order to provide the reflecting members 23 and 24, so the configuration of the reflecting members 23 and 24 can be simplified.
- the reflecting members 23 and 24 are arranged in the vicinity of the tow through holes 14J and 14K through which the cord such as a wire passes when the wheeled hydraulic excavator 1 is towed. Thereby, also from the front surface 14A side of the front attachment mounting plate 14 opposite to the reflection members 23 and 24, reflected light by the reflection members 23 and 24 can be visually observed through the pulling through holes 14J and 14K.
- the front attachment attachment plate 14 By using the front attachment attachment plate 14, the front reflection members 23 and 24, which are difficult to attach, can be easily provided at a position suitable for vehicle inspection. Moreover, since the reflecting members 23 and 24 (reflected light) can be viewed from the front through the pulling through holes 14J and 14K, the range in which the reflecting members 23 and 24 can be seen is also on the front of the front attachment mounting plate 14 It can be extended and can increase reliability and safety.
- the reflecting members 23 and 24 are disposed on the inner side in the left and right direction of the lower traveling body 2 with respect to the position of the pulling through holes 14J and 14K. It can be placed in a slightly recessed position from. Thereby, the reflecting members 23 and 24 can be protected from the collision of flying stones and the like and the adhesion of earth and sand.
- the reflection members 23 and 24 are provided on the front attachment attachment plate 14 so that they do not interfere with the movable member including the upper swing body 4, the work device 11, the front wheel 16, and the outrigger device 18. As a result, these movable members can be freely designed, and the downsizing and the improvement of the operation performance of the wheeled hydraulic excavator 1 can be achieved.
- the reflection members 23 and 24 are provided at positions where they can be viewed from diagonally front through the pulling through holes 14J and 14K of the front attachment mounting plate 14.
- the range in which the reflecting members 23 and 24 can be seen can be expanded to the front side by using the existing pulling through holes 14J and 14K, and visibility and safety can be enhanced.
- the reflecting members 23 and 24 extend in the front and back directions so as to be orthogonal to the front attachment mounting plate 14. Accordingly, the reflecting members 23 and 24 can reflect light emitted from the left and right sides of the vehicle body, that is, the side of the wheeled hydraulic excavator 1.
- the rear surface of the front attachment mounting plate 14 is adjacent to the traction through holes 14J, 14K on the inner side (working device 11 side) in the left and right direction of the lower traveling body 2 than the position of the traction through holes 14J, 14K.
- a screw seat 25 is provided at 14B.
- the mounting bracket 26 can be attached to the screw seat 25 by screwing the bolt 27 to the weld nut 25 B of the screw seat 25.
- a reflector 28 can be attached to the mounting bracket 26 such that a reflecting surface that reflects light faces the side of the vehicle.
- the direction of the reflector 28 (mounting bracket 26) can be easily adjusted simply by loosening the bolt 27. Furthermore, if the reflector 28 is damaged, it can be easily replaced.
- the reflector 28 is disposed with its reflection surface directed to the outside of the vehicle body. As a result, the reflector 28 can reliably reflect the light emitted from the outside of the vehicle body, and the reliability and safety can be enhanced.
- the case where the outrigger devices 18 as work attachments are attached to the front and rear ends of the chassis 12 is illustrated.
- the present invention is not limited to this.
- an outrigger device is attached to one side in the front or rear direction of the chassis, and the outrigger device is used in place of the outrigger device on the other side in the front or rear direction of the chassis.
- Another attachment such as a device may be attached.
- the reflector 28 of the reflecting members 23 and 24 is formed in a rectangular shape.
- the present invention is not limited to this, and may be another shape such as, for example, a circle, an oval, or a triangle.
- a wheeled hydraulic shovel 1 is illustrated as a wheeled working vehicle.
- the present invention is not limited to this, and can be widely applied to, for example, a wheel-type work vehicle that travels on the road by front and rear wheels such as a wheel-type hydraulic crane.
