The hydraulic stand 4 may for example comprise a manifold 9 for independently providing hydraulic power from a hydraulic power means 10 to each hydraulic cylinder 8.
In the hydraulic stand 4, at least one of the hydraulic cylinders 8 may be configured to be retracted by means of gravitational force and/or by means of spring force. If at least one of the hydraulic cylinders 8 is configured to be retracted by means of gravitational force and/or by means of spring force, said at least one hydraulic cylinder 8 can be configured to be retracted by means of gravitational force and/or by means of spring force after that the hydraulic pressure is released in said at least one hydraulic cylinder 8. It is also possible that at least one of the hydraulic cylinders 8 may be configured to be retracted by means of hydraulic power.
In the hydraulic stand 4 the top support structure may be provided with moving means 11 for moving a container 1 horizontally along an upper surface 12 of the top support structure. In such case, an upper surface of the top support structure for directly or indirectly supporting a container 1 may be provided with a polytetrafluoroethylene (PTFE) coating for facilitating moving of a container 1 horizontally along the upper surface of the top support structure. In the hydraulic stand 4 shown in the figures the moving means comprises adjusting screwing means 13 for horizontally moving a container 1 along the upper surface of the top support structure.
It is apparent to a person skilled in the art that as technology advanced, the basic idea of the invention can be implemented in various ways. The invention and its embodiments are therefore not restricted to the above examples, but they may vary within the scope of the claims.
