FIG.

  The support frame 1 is divided and formed in the middle of the horizontal frame and is separately formed in the front and rear, so that the front support frame 1A on which the front support 3 is arranged and the rear support 4 are arranged. And rear support frame 1B. Specifically, the support frame 1 is a rear portion of the midway connecting frame 36 and can be divided into a pair of horizontal frames 2c and 2d and a midway part of the midway connecting frames 37 and 37. 40 is formed, and is configured to be detachable with the front side support frame 1A, the rear side support frame 1B, and bolts through the dividing portion 40 (see FIG. 6).

  From FIG. 7, according to the support frame 1 that can be divided into front and rear parts, when removing the work vehicle packed and supported by the support frame 1 from the support frame 1, first, the front end side of the work vehicle is removed with a single crane. Lift up, in this state, the front and rear connections of the support frame are released, and only the front support frame 1A is removed (see FIG. 7A). Subsequently, the front side of the work vehicle is supported by a stand 35 or the like instead of the front support frame 1A, the fixing of the attachment portion 34 to the traction tool 33 side is released, and the rear end side of the work vehicle is held using a crane. By raising, the remaining rear support frame 1B can be removed (see FIG. 7B).

  According to this configuration, the crane can be detached from the support frame of the work vehicle with only one crane without using two cranes for lifting the front and rear at the same time or using a dedicated lifting tool. Since it is sufficient to lift only the front and rear sides of the work vehicle, the crane requires less force than when the work vehicle is suspended in the air. A low output is sufficient.

  Next, based on FIG. 8, the structure of the cover body which protects the said step mat is demonstrated. FIG. 8A is a diagram showing a divided structure of the cover body, FIG. 8B is a diagram showing the cover body applied to a narrow step mat, and FIG. It is the figure which showed the cover body applied to the wide step mat.

  The cover body 41 covers the right side of the step mat 16, covers the first cover portion 42 in which a notch 42 a into which the accelerator pedal is inserted is formed, and a range from the left end side to the center side of the step mat 16. The second cover part 43 formed in an L shape is divided and formed in a U shape in plan view according to the shape of the step mat 16.

  According to the cover body 41, the left and right widths of the cover body 41 are adjusted to be short by increasing the wrap width 44 between the first cover portion 42 and the second cover portion 43 (see FIG. 8B). By narrowing the wrap width 44 between the cover portion 42 and the second cover portion 43, the left-right width of the cover body 41 can be increased (see FIG. 8B).

  That is, according to this configuration, the step mat is a work vehicle in which the width of the applied step map 16 is different by adjusting the width that the right end side of the second cover portion 43 and the first cover portion 42 wrap. 16 can be covered. Therefore, it is not necessary to create a cover body for each vehicle type having a different width of the step mat 16, so that the cost can be kept low.
