Abstract: PURPOSE:To expand a working area and to improve productivity by maintaining a chair track of a closed loop in a trapezoid by four wheels and reversing a member which is carried in by adjusting an interval of the lower side wheels and adjusting the sag of the track by the normal rotation and the reverse rotation of the four wheels. CONSTITUTION:A closed-loop caterpillar 11 consisting of a chain is maintained in the trapezoid by the four wheels. The member 1 such as the long-size steel frame, etc., is carried from a chain conveyor 12 in the chain caterpillar 11 which is rotated normally. After the member 1 is taken in the sage 13 taking place on the chain caterpillar 11, the chain caterpillar 11 is stopped. At this time, the interval between the lower side two wheels is shortened. Next, the chain caterpillar 11 is rotated reversely and the member 1 is reversed in the sag 13. The chain caterpillar 11 is returned to the normal rotation and the member 2 after being reversed is carried out by a chain conveyor 16. The chucking time is shortened and the restriction of a reverse angle of the long-size member 1 is eliminated by this mechanism.
