However, since the winch 25 for the hook 24 is mounted on the upper surface of the boom 22 in the conventional mobile crane or the like, when the boom 22 is vertically undulated and moved, the hook 24 is suspended. The lowered wire ropes 26 may intersect near the tip of the boom 22 and interfere with the subsequent vertical movement operation of the hooks 24. It is an object of the present invention to provide a crane vehicle that can smoothly perform vertical movement operation without the wire ropes intermingling even when the boom is vertically swung up and down.

[Operation] The boom is raised and lowered from the front to the rear or in the opposite direction. The tip of the boom gradually rises on the swivel base to be in a vertical state, and further rises and falls in the opposite direction. At the same time, the hook suspended on the winch at the boom tip also moves. Thus, even if the boom is raised and lowered, since the winch for the hook is attached to the tip of the boom, the hook moves without the wire rope for the hook intersecting. Therefore, the subsequent vertical movement operation of the hook can be smoothly performed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. As shown in FIGS. 1 and 2, a mobile crane 1 has a swivel base 3 mounted on the upper part of a vehicle body 2 so as to be capable of horizontally swiveling 360 degrees, and a telescopic boom 4 mounted on the swivel base 3. A hoisting means 5 is provided between the swivel 3 and the boom 4, and the hoisting means 5 is composed of a motor M and a gear 7 meshing with a gear 6 of the motor M. In addition to the present embodiment, a mechanism such as a rack or pinion can be used as the undulating means 5.

Next, the operation of this embodiment will be described.
When the boom 4 is moved rearward from the front or forward from the rear at the work site, the swivel base 3 is normally rotated to move the boom 4. However, when the work site is narrow or there is an obstacle around the work site and the boom 4 cannot be turned, the boom 4 must be undulated in the vertical direction indicated by the arrow A in FIG. 1 to move the suspended load 13. I won't.

In this case, the motor M of the hoisting means 5 is operated to rotate the gear 6 and the gear 7 of the motor M to hoist and rotate the boom 4 in the direction of the arrow shown in FIG. The up-and-down rotation of the boom 4 is possible up to 180 degrees as shown by the chain line.
The boom 4 gradually rises at its tip on the swivel base 3, passes through the vertical state, and then moves in the opposite direction.

The hook 11 hung by is also moved in the opposite direction. At this time, the winch 8 for operating the wire rope 10
Since the wire rope 10 is attached to the tip of the boom 4, the wire rope 10 can move the hook 11 without crossing.
Therefore, the vertical movement operation of the hook 11 after the movement can be smoothly performed. As described above, according to the present embodiment, even when the work site is narrow and the swivel base cannot be swung, the boom 4 can be vertically swung up and down to smoothly move the suspended load 13.
