Annotation The analysis of the used belt conveyor transport has shown inefficiency of further increase in the angle of inclination and mass of the transported cargo by existing methods. A steeply inclined belt conveyor with fan-shaped transverse benches is proposed, which allows to increase not only the angle of its inclination, but also the mass of transported cargoes due to more efficient filling of the working space of the tape and counteraction to gravity forces. The proposed design of the conveyor significantly increases the effectiveness of dust suppression in the process of transporting bulk materials. The construction of the slope belt conveyor is protected as intellectual property in the form of patents for invention. The method for calculating the steeply inclined belt conveyor in the part of determining the forces and stresses acting on the clamping lever is specified. A graphical and mathematical model of the scheme of force interaction of structural elements and transported material is proposed. The equation of the maximum bending moment due to the structural features of the conveyor is obtained, which makes it possible to calculate the geometric parameters of the clamping lever, as well as the necessary force for the spring. An essential non-linearity of the dependence of the mass of the steeply inclined belt conveyor on its angle of inclination at a given conveyor capacity and the height of the lift of the transported cargo is presented. It is shown that, taking into account the limitation of the angle of inclination of the belt conveyor due to the decrease in the positive friction of frictional forces with its growth, at a certain value of the angle of inclination, the mass of the conveyor increases in proportion to the growth of the lifting height of the transported material while maintaining productivity. Taking into account the influence of the friction coefficient, gravity force of the additional force transferred to the diaphragm, presser lever and conveyor belt, the optimum range of the conveyor angle is determined, which reduces its material capacity at a given capacity in comparison with the known conveyors
