PCT No. PCT/SE87/00548 Sec. 371 Date Jul. 29, 1988 Sec. 102(e) Date Jul. 29, 1988 PCT Filed Nov. 20, 1987 PCT Pub. No. WO88/04276 PCT Pub. Date Jun. 16, 1988.A lifting system for a container includes four lifting columns each removably connected to one of four vertical corner edges of the container. Each lifting column is telescopable with the aid of power means driven by a power source via a control system. The lifting columns are in pairs forming two separate lifting aggregates placed at opposite sides of the container. Each lifting aggregate is connected in a closed loop circulation circuit including connecting piping from respective controls to the first lifting column, a first interconnection from the first lifting column to the second column and a second interconnection from the second lifting column back to the control. The first closed loop at one side of the container is completely separate from the second closed loop at the other side of the container and in effect synchronous, equal displacement of the lifting column for each separate lifting aggregate. |
