Hydraulic excavator

A lower traveling structure () having front wheels () and rear wheels () provided on a chassis () extending in a front and rear direction, an upper revolving structure () rotatably mounted on the chassis (), and a working mechanism () provided on a front side of the upper revolving structure () and at an intermediate position in a left and right direction are provided. On the other hand, a towing through hole (J,K) bored through an upper side position on both left and right sides and in a front and rear direction and used for mounting a cable in towing is provided on a front attachment mounting plate () provided on a front side position of the chassis () constituting the upper revolving structure (). Moreover, a reflecting member () located inside in the left and right direction of the lower traveling structure () from the position of the towing through hole (J,K) and in the vicinity of the towing through hole (J,K) and reflecting ambient light is provided on a rear surface (B) of the attachment mounting plate ().

Wheel type working vehicle

An earthmoving apparatus includes an earthmoving blade () extending in the width direction of an undercarriage, a lifting unit () configured to move the earthmoving blade () up and down, and a cover unit () covering the lifting unit (), wherein the earthmoving blade () can be moved by the lifting unit between a grounded position in which the earthmoving blade is in contact with the ground surface and a retracted position in which the earthmoving blade is held highest off the ground surface, while keeping a nearly vertical orientation with respect to the ground surface, the cover unit () includes a sub cover () extending from a location above the lifting unit () toward the earthmoving blade () and a main cover () slidable on the upper surface of the sub cover (), the main cover () is pivotally attached to the earthmoving blade () in such a manner that one end portion of the main cover is nearly in contact with the top surface of the earthmoving blade, and when the earthmoving blade () is in the grounded position, the other end portion of the main cover overlaps with the sub cover ().
