Abstract
The knee-lever linkage is attached between the elevating platform and the base. Of two hydraulic cylinders, one is fixed to the lower end of the vertical guides and parallel to it and has its other end connected to the elements which control the movement of the front part of the platform in these guides. The second hydraulic cylinder is telescopically constructed and connected between the lever arm part of the knee-lever linkage fixed to the platform and the base and together with the first cylinder effects the lowering or raising of the platform to the required position.
