Powerful modern hoisting machines perfectly serve mines up to 800 ts depth. Lifting machines for mines of greater depth (not counting lifting machines with friction pulleys, which have known disadvantages) should have either drums of larger sizes than currently manufactured, or the possibility of using a double-layer coiling rope on the drum. New machines, unlike the existing ones, should have less weight and better qualities.

This paper presents the author's proposed technical method for the calculation of shaft hoisting machine drum shells developed in the thesis. The analytical solution of the questions of calculation and design of drum shells of mine hoisting machines was proposed by B. L. Davydov. However, this general method has not been applied in technical calculations as cumbersome and at the same time approximate, not giving specific design formulas. B. A. Morozov developed the general and on its basis the technical methods of calculation of drum shells of mine hoisting machines (see article). The use by the Novo-Kramatorsky plant named after Stalin of the method of calculating the strength of the submarine hull of Yu. A. Shimansky to calculate the shells of the drums of mine hoisting machines gives approximately the same results as the method of B. A. Morozov. A. Morozov. The above noted disadvantages are largely eliminated in the proposed technical method for calculating drum shells of mine hoisting machines, built on the basis of the general theory of the cylindrical shell using the proposals of B. L. Davydov and V. A. Morozov, verified by practice or experiments, in the part of determining the load on the drum shell.
