１全体が対地的に浮上することになる。When the vehicle body is lifted, the lower end of the stand 15 is tilted and grounded. Therefore, the operator puts his / her foot on the upper surface of the grounding stability holding member 14 provided at the lower end of the stand so that the grounding point at the lower end of the stand does not move, puts his / her weight on the foot, and fixes the state. By operating the traveling operation lever 8, the traveling crawler 2 is driven to advance the machine body. Then, the stand 15 bulges the ground and stands up, and the entire grounding stable holding member 14 is grounded to maintain the standing stable posture, and the front portion of the vehicle body is lifted. Then, by lifting the rear portion of the vehicle body with the jack 17, the entire traveling crawler 1 is floated above ground.
