Testbench for testing continuous operation machines in which one installs on platform a frame with platform and two entrance apparels, to the frame one attaches loading devices that are installed in horizontal positions hydro-cylinders in such way that with their bodies those are hinged to frame and the rods of hydro-cylinders at one side are connected to the piston that is in the body of hydro-cylinders and to the other end of the rods bearing is connected in such way that its plane of rotation coincides with vertical plane, with support at convex side of plates that with the lower part are hinged to frame and with concave side are turned to the side of the apparel, hydro-cylinders are included to hydro-system of loading device in such way that to the fittings that supply liquid to the piston gravity of hydro-cylinders pressure main of system is connected, this is fed from hydro-pump through check valve, and the fittings connected to rod cavity of hydro-cylinders are connected to discharge mains directed to tank, besides that the fittings are connected to the tank through controlled safety valve. |
