The invention comprises a method of loading or unloading a transportable container onto or from a transporting vehicle. The method involves engaging each of the four corner regions of the container (3) with an apparatus (1, 43) having a powered extendable and retractable leg (2). To unload the container from the transporting vehicle shown in Fig. 5, each leg (2) is synchronously lowered so that they engage the ground surface and accordingly lift the container (3). The transporting vehicle is then moved from under the container (3). Alternatively, if the container (3) is to be loaded onto the transporting vehicle shown in Fig 5, the deck of the transporting vehicle is positioned under the container (3) once the legs (2) have been lowered. Then, synchronously each of the legs (2) is raised so as to lower the container (3) onto the ground or to lower the container (3) onto the deck of the transporting vehicle. Each apparatus (1, 43) is then disengaged from the corner regions of the container (3). The invention also relates to the apparatus for loading or unloading a container (3) onto or from a transporting vehicle. Four lifting devices (1, 43) are provided each having an extendable leg (2) formed by a piston and cylinder assembly. Each lifting device (1, 43) has a peg (4) which engages an upper aperture in a container (3), a second locating means (20) is provided for engaging the lower part of the container (3) and a foot (31) for contacting the ground surface. The apparatus can be used to relocate containers (3). |
