PURPOSE:To hold a container horizontally and to eliminate swinging and tilting of the container at the time of unloading thereof by providing container supporting arms and an auxiliary arm pivotably front-to-back and defining a parallelogram by the pivoting points, a supporting portion and a connecting portion. CONSTITUTION:There are provided on both rear sides of the body 1 supporting arms 3, 3 adapted for supporting a container 2 and pivotable front-to-back by means of hydraulic cylinders 4, 4. There is provided at a depression 14 formed in the central front portion of the body 1 an auxiliary arm 8 pivotable front-to-back and, when a container 2 is loaded, extending under and in front of the container 2 and provided at an end with a connecting portion for connection to the container 2. There is further provided in the depression 14 a stopper 16 for preventing the auxiliary arm 8 to be pivotally moved backward exceeding a predetermined point. The pivoting points of both arms 3, 8, the supporting portion 5 and the connecting portion 13 are so arranged as to define a parallelogram so as to hold the container 2 horizontally at all times. This eliminates, with no specific power, swinging and tilting of the container 2 which be caused when unloading of the container 2.
