PROBLEM TO BE SOLVED: To provide a crawler type irregular ground work vehicle that can stably travel on a sloping ground and an irregular ground whose irregularity is great and has improved operability.SOLUTION: The crawler type irregular ground work vehicle comprises a vehicle body frame 10, at least a pair of left and right crawler travel devices 60 and a suspending device 70 that suspends the pair of left and right crawler travel devices 60 onto the vehicle body frame 10. The suspending device 70 is constituted of: a pair of left and right towing arms 71, extended in a longitudinal direction, one ends of which are supported in the vehicle body frame 10 to be rotatable in a lateral direction as a center and the other ends of which are supported in the crawler travel devices 60 to be rotatable in the lateral direction as a center; a swinging arm 72 that is extended in the lateral direction and supported in the vehicle body frame 10 to be rotatable in the longitudinal direction as a center, at the center in the lateral direction; and a pair of left and right connection arms 73, one ends of which are connected to the swinging arm 72 through a universal joint 82 and the other ends of which are connected to the crawler travel device 60 through a universal joint 83.

    【課題】傾斜地や凹凸の激しい不整地において、安定して走行できるとともに操作性が向上したクローラ式不整地作業車両を提供する。【解決手段】車体フレーム10と、少なくとも左右一対のクローラ走行装置60と、左右一対のクローラ走行装置60を車体フレーム10に懸架する懸架装置70とを備えるクローラ式不整地作業車両において、懸架装置70は、前後方向に延設され、一端が車体フレーム10に左右方向を軸として回動自在に支持され、他端がクローラ走行装置60に左右方向を軸として回動自在に支持される左右一対の牽引アーム71と、左右方向に延設され、左右方向の中心で車体フレーム10に前後方向を軸として回動自在に支持される揺動アーム72と、一端が自在継手82を介して揺動アーム72に連結され、他端が自在継手83を介してクローラ走行装置60に連結される左右一対の連結アーム73とからなる。【選択図】図9
