PURPOSE:To simplify the unloading and loading operations of a container, by successively operating a fastening means and a connecting means arranged between a inclinable frame and the container. CONSTITUTION:The inclinable frame 6 using as a driving source a hydraulic cylinder 5 is pivotally mounted as indicated at 7 to a car 1 for carrying a container 2 for holding powder or grain, and a connecting pin 9 is secured to the forward end of a reinforcing frame 9 of the container 2, and a fastening pin 11 is secured to the rear end so that the connecting means 11 and the fastening means 12 are faced. When the hydraulic cylinder 5 is extended, the frame 6 is rotated vertically together with the vessel 2 about the pivot 7, and then when a fastening cylinder 16 is extended, by the counter clockwise rotaion of the arm 17 a fastening hook 18 is disengaged from a fastening pin 10, and at the same time a guide roller 19 abuts on the reinforcing frame 8. Then by extending the connecting cylinder 13 to rotate the connecting arm 14, the vessel 2 can be unloaded onto the ground with it suported by connecting hook means 15, when the car 1 can be moved forward. |
