LIFTING TABLE Russian patent published in 2017 - IPC B21B39/04 

FIELD: machine engineering.

SUBSTANCE: table contains a lifting platform (13) with the engine (1), reducer (2) and drive shaft (3), at the opposite ends of which there are toothed wheels (4). When rotating, the gears (4) through the connection with the gear rack (5) are simultaneously moving in horizontal plane two drive racks (6), which are arranged in the rectangular cavity of the parallel bearing beams (12) of the platform (13). The drive racks (6) are centered in the parallel rectangular beams (12) cavity of the platform (13) by means of guide rollers with capability to move longitudinally. When moving, the drive racks (60) are rolled on the support rollers (10) by supporting strips (7) of the fixed part (8) of support pillars (14) and lift the platform (13). In the uppermost position of the platform (13) the supporting strip (7) rests by its lower horizontal part on the support roller (10) of the support pillar(14). The structure stability is provided by a telescopic form of the support pillars (14), which are simultaneously the guides for the vertical movement of the platform (13).

EFFECT: lifting tables reliability increase.
