A supporting platform (1) is described, equipped with a number of support means (2), in which a concentrated load (normally positioned in the middle of the platform) is uniformly distributed on the support means. Each support comprises (or is connected to) a piston (hydraulic or pneumatic), into which a pressurised fluid is introduced, and comprises means (11) for locking said piston in the position reached in response to introduction of the pressurised fluid. |
