In the future, in Ukraine it is planned to increase the sown area for cereals, legumes and oilseeds, to increase the gross grain harvest to 80 million tons, and its export abroad was increased twice. Intensive construction in the southern ports of Ukraine of grain transshipment terminals with large metal silos will solve the problem of increasing grain export in the future. At these powerful terminals, the bulk of the grain comes mainly by rail, and is shipped to water. The aim of the work was to study the characteristics of the grain receiving from railway transport to the grain transshipment terminal of LLC “Ukrelevatorprom” in order to improve its works efficiency. The object of the study was the development of technology of grain receiving at the grain transshipment terminal; the subject of research is cereals, legume sand oil crops, as well as data from daily volumes of receiving and dispensing operations at the grain transshipment terminal of LLC “Ukrelevatorprom” for 2015-2016. The studies were carried out on the basis of processing data from the consignment notes for 2015-2016, according to which there was a summed amount of grain (net) daily transported by the railway. Further processing of the obtained data was carried out by a combined graphoanalytical method, for which, on the basis of tabular values for each studied year, the corresponding histograms and graphs were built and the necessary indicators were determined. Analysis of the structure of grain crops supplied by railway to LLC “Ukrelevatorprom” in 2015 and 2016 and their ratio showed that the main share was occupied by cereal crops (78.0 % and 73.1 % respectively), which were mainly represented by corn, share which was significantly dominated by other crops (wheat of various classes and barley) and amounted to 45.8 % and 44.5 %, respectively, which can be explained by its high demand in the international grain market, in which Ukraine occupies a leading position. Oilseeds (rapeseed) were taken in accordance with 19.1 % and 14.9 %, and legumes (soybeans) — 2.9 % and 12.0 %. An analysis of the timing of the unloading of grain wagons (hopper cars) showed that the total duration of this process, depending on the crops, averages 37...59 minutes. The longest steps for unloading wagons are to determine the grain quality indicators, especially rapeseed, and to spill grain from the wagons, therefore, to reduce their duration, it is necessary to form feeds of wagons with grain batches of the same quality and use more modern express analyzers to determine grain quality indicators, which will increase the productivity of the grain receiving line from the railway. According to the research results, the enterprise has the potential to increase by about 30 % the volume of grain intake. It was established that the periods of the grain receipt at the enterprise in 2015-2016 amounted to 349 and 353 days, respectively, the actual coefficients of the daily irregularity Kdaily for the grain receipt from the railway in these years are equal to 1.47 and 1.52, and the monthly irregularity Kmonth, respectively 1.33 and 1.21, does not exceed the standard values Kdaily = 2.5 and Kmonth= 2.0. This made it possible to clarify the database from the actual characteristics of the process of grain receiving by railway and can be used in design and verification calculations of equipment in technological lines for receiving grain from railway transport, and will contribute to increasing the efficiency of grain transshipment terminals.

Introduction. Work of locomotive crew members (engine drivers and engine driver assistants) in railway transport is associated with exposure to complex of occupational hazards including psychoemotional stress and shiftwork (with night shifts) along with noise and vibration.Objective. To study influence of shift work (with irregular alternation of day and night shifts) on biorhythms disturbances in locomotive crew workers.Materials and methods. Polls, simulators of occupational activities with training complex «Cabin of engine driver EP1M», daily monitoring of blood pressure, statistic data processing by SPSS–20 software.Results. Findings are that 953 locomotive crew workers (94%) experienced sensations of temporary disorientation, slight dizziness, sleepiness, interpreted as monotony and sensor deprivation. 61% of the examinees demonstrated frustration signs, in 30% of the cases there were certain manifestations of mental ill-being — irritability, fatigue, weariness, absent-mindedness, anxiety; 27.2% of the testees experiences various sleep disorders; 13.8% of the workers complained of «light sleep», 2% of those — restless sleep, 0.6% — sleeplessness. In occupationally related biorhythms disturbance, the body undergoes occupational adaptation, with partial transformation for atypical schedule of sleep and wakefulness.Results. To preserve health, efforts should be aimed at adaptation to shifted occupational activities with safe adaptogenic medications, low-caloric diet for individuals working at irregular shifts, create conditions for adequate physical activity of the workers between shifts. Necessities also are individual norms for blood pressure parameters in engine drivers with night shiftwork, specification of antihypertensive treatment for patients with irregular shifted work.
