Zusammenfassung:	PROBLEM TO BE SOLVED: To improve the working efficiency by providing a first base to support a first working machine on an upper part of a traveling truck in a horizontally turnable manner, and providing a second base to support a second working machine on an upper part of the first base in a horizontally turnable manner. SOLUTION: A turning mechanism 3 capable of freely turning in the horizontal direction by 360 deg. is arranged on an upper part of a traveling truck 1. A first base 2 to support a loading shovel 4 is fixed to the turning mechanism 3. A turning mechanism 6 capable of freely turning in the horizontal direction by 360 deg. is arranged on an upper part of the base 2. A second base 5 to support a back hoe 7 is fixed to the turning mechanism 6. A turning mechanism 10 capable of freely turning in the horizontal direction by 360 deg. is arranged on an upper part of the base 5. An operation floor 12 on which an operator's seat and an operation lever group 9 are arranged is fixed to the turning mechanism 10. The loading shovel 4 and the back hoe 7 can be turned in the horizontal direction by 360 deg. without interference with each other, and the working efficiency can be improved.
