<p><P>PROBLEM TO BE SOLVED: To equip a rear part of a chassis with an engine, make a ground working device horizontally oscillatable, and enhance traveling stability and/or slewing workability. <P>SOLUTION: A chassis 4 having four front and rear wheels 2 and 3 is equipped with: a traveling drive unit 12 having the engine 13 and a power transmission mechanism 14; and a stabilizer 10 doubling as a dozer device, which is arranged in a front part and can freely ascend/descend and come into contact with ground. On the chassis 4, a base 6 of revolver is provided in a position lower than the highest position of the chassis 4 so as to be revolvable all around a pivot 5 via the pivot 5 and a pivot bearing 36. On the base 6, there are provided a driver seat 7, an operating device 8 which is arranged ahead of the driver seat 7, and the ground working device 9 which is arranged near the operating device 8. A working device supporting part 37 for supporting the working device 9 on the upside of the base 6 in a horizontally oscillatable manner is provided in a front part on the base 6. <P>COPYRIGHT: (C)2004,JPO</p> |
