Of course, after that, to the truck waiting on the platform 2, the trailer (T) loaded with the cargo or container loaded on the bucket 3 can be connected to the destination.

On the contrary, when the trailer (T) loaded with cargo or containers from the truck to the bucket 3 is loaded into the bucket 3 or the bucket 3 is returned to its original position, the reverse process is performed. . That is, when the trailer (T) is loaded in the bucket (3), the hydraulic pressure is supplied to the cylinder (22) of each position adjusting / rotating device 20 to pull the drive rod 24, the bucket (3) pivots The pin P is rotated about the central axis to start the return from the platform 2 toward the truck 1. At this time, the bucket 3 is smoothly rotated by the support rollers 12 of the rack 10 installed on the platform 2 on both sides.

As such, when the bucket 3 continues to rotate to reach the wagon 1, the bucket 3 is smoothly rotated by the respective rollers 388 provided on the support plate 386 of the lift device 30, and finally the wagon 1. It is aligned to the correct position of, the operation of the position adjustment / adjustment device 20 is stopped.

Thereafter, when hydraulic pressure is supplied to the cylinder 362 of the actuator 36 of the lift device 30 to operate in reverse, the rod 364 extends from the cylinder 362 to push each long pin 344 to both sides. The first link member 344 and the second link member 348 of the pair of links 34 are folded and lowered, and finally the bucket 3 is completely seated in the wagon 1.

Thus, when the bucket 3 is completely seated in the wagon 1, the fastening piece 242 of the drive rod 24 of each position adjustment / rotation apparatus 20 is provided in the side of the bucket 3 After releasing from the stationary piece 5, the cylinder 22 is operated to return the driving rod 24 to its original position, and the positioning / rotating device 20 is rotated toward each platform 2 to its original position. Return
