A method for loading and unloading load units on and off a vehicle, said load unit having first and second ends, the method comprising:

• providing a frame that has first and second ends and a dock in the first end for receiving a transferring device, whereupon the frame is loaded and unloaded on and/or off the vehicle by the transferring device when said transferring device is secured to said dock and operated by a hook system of the vehicle, and wherein said frame is fastened to the vehicle in a detachable manner;
• providing the transferring device used for catching and transferring the load unit on or off the vehicle, the transferring device comprising:
• a catching device, which is used for catching said load unit and for transferring it on or off the vehicle when the transferring device is operated by said hook system of the vehicle;
• and
• two elongated arms, at least one arm joined to said transferring device via a hinge, where said hinge is arranged in a proximal end of the at least one arm, whereupon longitudinal axes of said two elongated arms form an angle, said arms having said catching device arranged in distal ends of the arms;
• and
• a gripping point, which is gripped by the hook system of the vehicle,
• wherein said transferring device has open and closed positions, wherein in said open position the angle between the two elongated arms is bigger than in said closed position and wherein in said open position said catching device is configured to be introduced to/from the load unit and wherein in said closed position said catching device is configured to be fastened to the load unit, thereby allowing catching and transferring the load unit;
• and
• catching the load unit and transferring the load unit on and off the vehicle by the transferring device.
