PROBLEM TO BE SOLVED: To provide a crawler travelling device which flexibly corresponds to a slope irrespective of extent of an inclination angle of the slope to be traversed and permits stable slope traverse, in the crawler travelling device capable of vertical differential movement which changes vertical positions of two crawler travelling bodies.SOLUTION: A crawler travelling device includes: two elevation guide units 102, 103 which are supported by two crawler travelling bodies 2, 3 and are freely swingably coupled while being respectively protruded to the upper side; and one movable coupling part 110 which is arranged between two elevation guide units and is configured such that a height position on each elevation guide unit can be individually changed. Therein, the maximum height difference between two crawler travelling bodies produced by changing a position for each elevation guide unit by means of the movable coupling part exceeds a height size of each crawler travelling body.SELECTED DRAWING: Figure 4 |
