PURPOSE: To perform raising and lowering of a machine body by means of a slight force by arranging a stand for elevating a machine body in the position of the center of gravity in the longitudinal direction of a machine body.
CONSTITUTION: A support axle 10 is caused to laterally span in the vicinity of the position (a longitudinal balance position) of a center G of gravity in a longitudinal direction of a car body 2 having a running crawler 1 and supported rotatably around the axis thereof by means of a bearing. The base part of a stand arm 11 is engaged with the support axle 10 and a ground touching stabilizing holding member 12 is arranged in an L-shape as seen from a side to the tip of the arm to constitute a stand 13 for elevation. The stand 13 is arranged in a state that it is rockable in the advancing direction (a longitudinal direction) of a machine body around the axle 10. Thus, after a car body is lifted up with the aid of the stand 13 for elevation, the whole of a machine body can be stably supported in a ground touched state at two points, one of which is an auxiliary stand 14 at the front part of a car body and the other is an auxiliary stand 15 at the rear part thereof.
