Annotation: In article the analysis of influence of speed of movement of the conveyor on intense-state of strain designs of trellised conveyor passageways by span of 18 m and 30 m. has been carried out. Research on spatial rod settlement models with the account of dynamic character of technological loading has been also carried out. As a result of numerical experiments, dynamism factors on internal efforts for the basic structural components of trellised conveyor passageways have been received. For the most intense elements the dynamism factor on internal efforts makes a range from 1.20 to 1.26, the increase in pressure in relation to the pressure received by a standard technique (Textbook of conveyor gallery design (to SNIP 2.09.03-85)) makes from 16.1 to 19.5 %.
Keywords: constructions of trellised conveyor passageways, dynamic loadings, tensely-state of strain, dynamism factor on internal efforts, coefficient of utilizations of sectional views.
