PURPOSE:To enhance the availability factor of a self-propelling vehicle, by supporting a hopper carrier bed elevatably and rotatably to a main beam which is supported elelvably and rotatably to the upper surface of a mobile machine frame, and by enabling a hopper of a working machine carrier frame to be interchangeably attached to the abovementioned carrier bed. CONSTITUTION:A main beam 3 which is elevatably and rotatably about a support shaft 30 attached to the upper surface of a machine 1 that is tracted by a crawler type propelling unit 2, is rotated by a hydraulic device 40. A hopper carrier bed 5 is supported on the main beam 3 so that a support shaft 50 attached to the lower surface of rear side of the hopper carrier bed 5 is journalled to a rising section 3a provided in the rotatary end section of the main beam 3, and is elevated and rotated by means of a hydraulic device 42. Further, a carrier frame 8 for attaching a hopper 6 or other working machines may be interchangeably and removably attached to the carrier bed 5. Further, the working machine carrier frame 8 is composed of an assembling section 80 assembled onto the carrier bed 5 and a working machine carrier section 81 suspended from the section 80. |
