Abstract: A system for adjusting surface level, comprising a moveable surface; a mechanism adapted to be disposed between and coupled to the moveable surface and a fixed surface; a force transfer mechanism configured to be coupled to the mechanism for displacement of the moveable surface relative to the fixed surface; and a plurality of stopping rods, disposed between the moveable surface and the fixed surface, which are operative for restricting an axial movement of the moveable surface relative to the fixed surface in a first mode of operation and for restricting a radial movement of the moveable surface relative to the fixed surface in a second mode of operation.
