Abstract

PURPOSE:To increase the turning performance of a traveling device by testing downward a center rolling wheel for guiding the middle lower part of a wound crawler so that it can be adjusted freely in vertical direction, providing a bogie type moving arm with front and rear rolling wheels attached to the front and rear of the center rolling wheel, and energizing the moving arm by spring to tense the outside wheel downward. CONSTITUTION:Intermediate rolling wheels 4a to 4c are mounted on a connecting body 12 in the middle of a crawler 3 wound between a drive sprocket 1 and a track roller 2. Then the connecting body 12 and intermediate track idler rollers 4a to 4c are tensed downward through a mounting arm 13, a hydraulic cylinder not shown in the figure, and a shock absorbing spring 15. At the front and rear of the intermediate track idler rollers 4a to 4c, front track idler rollers 5a, 5b, 6a, and 6b are positioned by means of moving arms 7 and 7' moved around pivots (a), respectively. An energizing forces of springs 8 and 8' is applied to the moving arms 7 and 7' to move the outside track idler rollers 5a and 6b pressingly downward, respectively.
