The invention relates to special lifting and supporting equipment for a computer. The equipment comprises a fixed platform, wherein three parallel branched chains are evenly mounted on the upper end surface of the fixed platform in the axial direction, upper ends of the three parallel branched chains are evenly mounted on a moving platform, four rigid lifting branched chains are evenly mounted on the upper end surface of the moving platform in the axial direction by the aid of screws, a No.4 hydraulic cylinder is mounted in the middle of the upper end surface of the moving platform, and an upper mounting circular truncated cone is mounted at upper ends of the four rigid lifting branched chains and the upper end of the No.4 hydraulic cylinder and is used for placement of the computer; the parallel branched chains comprise No.1 lug seats, lower ends of the No.1 lug seats are welded on the upper end surface of the fixed platform, a No.1 hydraulic cylinder is mounted among the No.1 lug seats by the aid of a hinge pin, the top end of the No.1 hydraulic cylinder is in threaded connection with a connecting barrel, and the connecting barrel is in threaded connection with a spherical hinge. With the adoption of the equipment, a stable rigid lifting supporting function for the computer can be realized, and a new way for rigid lifting supporting of the computer is provided.
