Useful model relates down the load-lifting devices, down by the contacting with the earth equipment of transportation means for the lift, more precise to the installations with the screw jacks it can be used for lifting railroad transportation means, for example freight railroad cars, for the repair and the maintenance. Purpose of the proposed installation - increase in the reliability of the work of all units and simplification in the system of its control. The proposed technical solution provides for the use of more progressive material of shock absorber - the rubber is used instead of the tree, the electrical circuit of electrical equipment of the installation of jack stationary is additionally equipped for the sake of the system of control besides the synchronization of the displacement of the sliding beams of each jack, which forms part of the installation of jack stationary, and also for the sake of the step-down transformer with an output voltage of 12 [v] for the electric power supply of portable lamps with the possibility of their fastening before any place of different components of the construction of the installation of jack stationary, before the upper part of the housing of carriage detachable adaptation for cleaning and lubrication of the working section of cargo screw before the composition of the housing, whose upper part they are equipped for the sake of the change annular brushes of different hardness before the axial direction, is fixed, and before the housing the installed capacity for positioning the lubricant, connected by channels with the surface of cargo screw, castings - paw, support, cover and housing of reducer, the housing of nut, flywheel - are prepared based on carbon steel and/or gray cast iron with the use of the modifying mixture in the form of rare-metal oxides and restorer, predominantly cryolite of technical; moreover the working end of the welded paw is executed before the cast form. 3 [zav].[p]. of formula, 3 Fig.
