ABSTRACT:
A jacking device, which is, for example, used for lifting a motor vehicle when repairing it, includes at least one jack installed in a floor pit and including at least two horizontally spaced apart parallel pairs of links which are designed for simultaneous movement in two parallel vertical planes, respectively. A mechanism is associated with the links for moving them vertically. A table is horizontally supported on the links for lifitng e.g. a motor vehicle. Each pair of links consists of a first link and a second link which are so connected to each other as to form an X-shaped assembly when they are raised to raise the table. The first links in those two pairs of links are parallel to each other, and the second links are also parallel to each other. The links and the link moving mechanism are foldable into the pit when the table is lowered to close the pit. Each of the second links has a lower end supported in the pit slidably along one of a pair of sidewalls of the pit, while each of the first links has a lower end supported rotatably in the pit at one end thereof. A horizontal pit cover is connected to the second links slidably therewith for closing the pit which is opened when the table is raised. A mechanism including a pair of slidable brackets connects the cover to the second links for allowing the cover to slide with the second links.
