The platform has a floor structure (11) located on a substrate (15), on which a platform segment (1) is displaceably arranged, where the platform is located on the substrate. The floor structure is provided with a reservoir and a fluid reservoir, the displacement of the platform segment based on the substrate is caused by supply of a fluid i.e. oil, into the reservoir. The platform segment is displaceably arranged on the floor structure by a set of balls (3), where each of the balls is coupled with a lifting mechanism i.e. hydraulic lifting mechanism. |
