PURPOSE:To obtain a compact form on transportation and accommodation by installing leg parts which can shift horizontally and can be extended and contracted by an inner cylinder apparatus onto the base board of a transfer apparatus and permitting the transfer apparatus to override an obstacle easily. CONSTITUTION:The total length l1 of a transfer body 1 is reduced by shortening the all leg parts LEG 1-4, and the necessary space for transportation and accommodation can be reduced. In changing direction, the leg parts of an upper body 5 are raised, keeping the leg parts of a lower body 7 in grounded state, and then the upper body 5 is turned, and the all leg parts of the upper body 5 are lowered until the leg parts of the lower body 7 are floated-up, and then the lower body 7 is turned. When an obstacle 41 is over-rided, the transfer body 1 only passes a gap l2, taking account of a suspended wall surface 39, by selecting the extension and contraction degree of the outer cylinder L1 and the inner cylinders L2 and L3 of the leg parts of the transfer body 1. |
