FIELD: mechanical engineering; load-handling facilities. ^ SUBSTANCE: proposed load-lifting table has base, movable platform and platform lifting drive. Base and movable platform are hinge-connected by main and additional pairs of intersecting levers of scissor type. Supports of hinge joints of main and additional pairs of levers are secured at edges of base and movable platform. Lifting drive is furnished with short and long axles and power cylinders installed in hinge joints of intersecting levers of main and additional pairs. Power cylinders are mounted by their bases on long axle, and they are mechanically coupled by rods through bell crank installed on short axle. ^ EFFECT: provision of uniform lifting of movable platform, improved operation reliability, minimum overall simplified design. ^ 2 dwg |
