LIFT Russian patent published in 2006 - IPC B66F7/06 B66F3/22 

FIELD: mechanical engineering; lifting facilities.

SUBSTANCE: invention relates to lifts with scissor-type mechanisms. Proposed lift has base, load platform and articulated lever mechanism in between. Said mechanism includes at least two hinge-connected intersecting levers, some ends of which are mounted in guides secured, respectively, on platform and on base, with which other ends of levers are coupled, and extensible drive in form of pair of power hydraulic cylinders whose rods are mechanically coupled with common axle of intersecting levers by means of bell crank. Base of first power hydraulic cylinder is hinge-connected with axle of lower end of one of levers hinge-connected with said base. Base of second power hydraulic cylinder is hinge-connected with axle on lower end of other lever fitted by said end in said horizontal guide for moving the base of second hydraulic cylinder.

EFFECT: improved reliability of lift.
