FIELD: transport. ^ SUBSTANCE: invention relates to lifting-and-conveying machines, particularly to hoisting tables. Proposed table comprises base, cargo platform hinged-lever mechanism arranged there between and telescoping drive. Aforesaid mechanism comprises two pairs of articulated crossed levers. End of said levers are arranged in guides secured to cargo platform and base. Telescoping drive is made up of the drive opposed hydraulic cylinders. Said pairs of crossed levers are located in vertical intersecting mutually perpendicular planes. Both pairs of crossed levers are pivoted together by ring and common pin. Said common pin is mounted in aligned holes in the ring diametral plane. First pair of crossed levers are mounted on their seat surfaces between the collar, on the ring outer surface. Second pair of crossed levers is mounted on common pin inside the ring. Rods of the first pair of hydraulic cylinders are fitted on said common pin between levers of the second pair by means of silentblock and can be removed therefrom. Rods of the second pair of hydraulic cylinders are fitted in and locked on threaded holes of said common pin. ^ EFFECT: reliable operation. ^ 17 cl, 15 dwg |
