Abstract
A lifting jack arrangement for lifting platforms. The lifting jack has a liftable and lowerable, dimensionally stable guide tube on the upper end of which support elements, for example for a motor vehicle, can be mounted. A driving unit would typically be coupled with the guide tube for lifting and lowering it. A stationary guiding sleeve has sliding elements which are in contact with the guide tube. The guide tube is coated with a reduced-friction, abrasion resistant sliding layer consisting of a permanently adhering synthetic material containing PTFE.
