<P>PROBLEM TO BE SOLVED: To provide a container carrier, capable of eliminating complicatedness in driving operation and operation mistakes in changing steering by changing flow of hydraulic fluid to a right and a left hydraulic cylinders from each other in reverse move of the container carrier. <P>SOLUTION: A plurality of front wheels and a single rear wheel are disposed on a right and a left lower frames 53L and 53R of a vehicle, and the hydraulic cylinders 75 and 76 are provided to be steered in opposite phases at the front and the rear. A steering valve 60 on a rotary shaft of a steering wheel 56, and a forward/reverse changing lever 58 are provided. The right and the left hydraulic cylinders are connected by a first hydraulic circuit 81, and the steering valve is connected to the right and the left hydraulic cylinders by a second hydraulic circuit 82. A change control mechanism 31 is provided on the second hydraulic circuit 82 to change flow of hydraulic fluid to the right and the left hydraulic cylinders on the downstream side of the steering valve in forward/reverse move. When the container carrier is reversing, flow of hydraulic fluid to the right and the left hydraulic cylinders 75 and 76 is changed from each other to that in forward move. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
