Laminated tension elements have the opposite ends connected to the base and the upper ends of the legs and the platform has clamp devices for clampingly engaging the laminated tension elements. One clamp device pertaining to each element is nonmovable in the direction of the legs on the platform while the other is movable on the platform in the direction of the length of the legs by power operated devices. The clamp devices pertaining to each tension element are selectively operable so the platform can be moved along the legs.
