CRAWLER TYPE WORK VEHICLE

摘要

PROBLEM TO BE SOLVED: To provide a crawler type work vehicle capable of securing travel stability of a machine body, and improving comfortableness in turning by improving grounding performance of grounding wheels in getting over ridges. SOLUTION: A plurality of grounding wheels 9 to guide the grounding side of a crawler belt 12 are separated into a plurality of groups each comprising a plurality of the grounding wheels 9 adjacent to each other in a forward-backward direction. The grounding wheels 9 in each group are rotatably supported by a wheel bracket 19. The wheel bracket 19 right after a drive wheel 10 in the forward-backward direction of the machine body to be adjacent to it is supported on a balance frame 50 to be respectively supported around an axial center in a lateral direction of the machine body in such a way that a balance can oscillate. The balance frame 50 is supported on a truck frame 7 around the axial center lateral to the machine body in such a way that the balance can oscillate. COPYRIGHT: (C)2004,JPO
