The storage box has, at the front side of the right side, a notch that is obliquely cut from the upper side of the inner end in the left-and-right direction of the crawler to the rear side of the left and right outer sides. The notch has, at the lower side thereof, the upper face of the crawler that provides a space S usable as a scaffold for a worker or as a temporary storage space.

1. A hydraulic shovel, comprising: a lower traveling body having a left crawler and a right crawler for supporting the hydraulic shovel on a ground surface; an upper rotating body that has a rotating frame constituting a supporting structure and that is rotatably supported by the lower traveling body; and a storage box provided at a front side of one of a left side and a right side of the upper rotating body, characterized in that: an upper face of the storage box can be used as a platform path to get on an upper face of the upper rotating body from the ground when the upper rotating body is in the same direction as the crawler, the storage box includes a front face that is parallel to a direction perpendicular to a longitudinal direction of the upper rotating body and has an outer side end positioned at an upper side of the crawler at a portion of a track of the crawler that is supported by an upper roller and is substantially horizontal to the ground surface, an inclined face obliquely extending in a rearward direction above the track from the outer side end of the front face to an outer side face of the storage box to form a notch, and the outer side face is parallel to the longitudinal direction of the upper rotating body and that extends above the track, and the notch is configured to support a standing worker or an object placed by a worker when the portion of track is adjacent to the notch.

2. The hydraulic shovel according to claim 1 , characterized in that: an outer side face of one of a left side or a right side of the upper rotating body has a catwalk extending in the longitudinal direction and a platform scaffold is positioned at a lower side of the inclined face or the outer side face of the storage box so that the platform scaffold is continuous with the catwalk.

3. The hydraulic shovel according to claim 1 , in which a platform scaffold to get on or get off the upper face of the storage box is provided and positioned at the inclined face.

4. The hydraulic shovel according to claim 1 , in which a platform scaffold to get on or get off the upper face of the storage box is provided and positioned at the a lower side of the inclined face.
