Title:
CRAWLER TRAVELING VEHICLE
Document Type and Number:
Japanese Patent JP3160200
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To attain stable traveling even on a road surface with a steep incline by providing elongating and contracting means for connecting a crawler lower traveling body to an upper loading body, which are provided on the front and rear parts on both right and left sides of the upper loading part and elongated and contracted in the direction of top and bottom, and an inclination detecting means for detecting the angle of inclination of the upper loading part.
SOLUTION: A drive sprocket 22 and an idler wheel 23 of a tumbler engaged with a crawler belt 21 are provided on the inner surface side of the crawler belt 12, and the center of the outer periphery is built up to be domed. Further, hydraulic cylinders 11 (11A-11D) are provided on the front and the rear on both. right and left sides of an upper loading part in such a manner as to be elongated and contracted in the direction of top to and from bottom, thereby connecting the lower traveling bodies 20 and the upper loading part 30. The front and rear of both right and left sides of the upper loading part 30 are respectively provided with an inclination detecting sensor, whereby the start of a traveling vehicle's tilting down forward is detected and output to a control part to control a hydraulic circuit in such a manner as to horizontally keep the upper loading part. Thus, roll or the like can be prevented so as to enable stable traveling.
