る。Since the work boom 4 and the weight 5 are provided on the swivel base 3, even if the upper traveling body C including the cockpit 12 is elevated to a high place, the work boom 4 and the weight 5 still remain on the swivel base 3. 4 and weights 5 and the work booms 4 and weights 5 have a large weight, therefore, as shown in FIG.
The position of the center of gravity G can be suppressed to a slightly higher position, and the traveling body A secures the position of the lower center of gravity G, and can travel in a stable state. Further, the power unit 13 is provided in the upper traveling body C, and does not sink into water even when performing work for shallow water such as a river, and the power unit 13 operates similarly to a land state and is good. You can work in shallow water. The work boom 4 is connected to the boom pivot support 4a on the swivel base 3 of the traveling body A, and
As described above, excavation work can be performed at a low position without rising, and stable work can be performed in the same manner as on land.

Since the elastic body B is a work machine for shallow water having a rectangular sectional shape, the section modulus becomes larger than that in the case where the elastic body B has a circular sectional shape, and the mechanical strength in the height direction of the elastic body B is improved. In addition to being able to perform, the elastic body B has the advantage of being able to prevent the occurrence of idling, which is seen when the elastic body B has a circular cross section, by having a rectangular cross section.

The stretchable body B includes the tubular tubes 6a, 6 adjacent to each other in the stretchable portion 6.
Since the sliding portion 9 having less friction is provided between the voids of a so as to be in a superposed state, the working portion for shallow water is provided. Not only can the cylindrical tubes 6a, 6a that are adjacent to each other in a superposed state come into direct contact with each other to prevent an increase in frictional resistance, but also the sliding state between the adjacent tubular tubes 6a, 6a can be prevented. It can be made excellent and can be made watertight, the infiltration of muddy water in underwater work can be eliminated, and the mechanical efficiency can be improved.
