Abstract. The article is directed on the increase of bearing strength of the hydraulic props of mechanized fastening. In approaching of flat deformation and repeatedly static loading of corps of hydraulic prop of the mechanized fastening 3КD90, executed estimation of the maximum state of knot at the use in its construction of fixed autho-faste glowed or application of bi-slice corps. It is set that serial construction of hydraulic prop (with the coefficient of thick-walled 1,2) and using in it material (steel of 35ХГСА, p = 1000 MPa) not resilient mode of exploitation of corps at the increase of pressure of to 150 MPa at strengthening of corps of hydraulic cylinder of bandaging, autofaste, by application of alloyed stamp steels and alloys. For providing of the resilient mode in the noted range necessary increase of thick-walled corps to to m 1,4 at the use of autho-faste one-sliced corps or bi-slictd bandaging chart.
Keywords: Keywords: hydraulic cylinder of the mechanized fastening, maximum durability, charts of strengthening, automatic bond, multilayer, high-strength stamp steels and alloys.
