SMALL REVOLUTION TYPE EXCAVATION VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide a small revolution type excavation vehicle allowing installation of two point suspension parts out of three-point suspension parts of a car body in parts except for a counterweight and a machine cab box straddling over the gravity center, or more practically to provide a three-point suspension device for small revolution type excavation vehicle. SOLUTION: This small revolution type excavation vehicle 1 is so formed that the two point suspension parts 22 out of the three point suspension parts for suspending the whole car body are installed between the revolution center A of a revolving superstructure 3 and the machine cab box front wall 10a straddling over the car body gravity center position B in the car body lateral width direction. The two point suspension parts out of three point suspension parts are thus provided near the car body gravity center position so that the vehicle can be suspended in a well-balanced state as a whole. The two point suspension parts out of three point suspension parts are installed between the revolution center of the revolving superstructure and the machine cab box front wall straddling over the car body gravity center position in the car body lateral width direction so that its circumference is hid by the exterior to improve the vehicle external appearance design.
