The study deals with basic problems that are associated with the features of exploitation of combine harvesters of CLAAS LEXION 750,760 TERRA TRAC. The analysis of constructions of reaping-machines, sloping chambers, threshing machine, cleaning, system of growing and distributing of uncorn part of harvest shallow, caterpillar working system of combine harvesters of CLAAS LEXION 750,760 TERRA TRAC was made. The structural and technological decisions of reaping-machines, threshing machine, cleaning, system of growing and distributing of uncorn part of harvest shallow are solved, which allow collecting grain crops, soybean, pea, rape with minimal losses. The features of construction and exploitation of the caterpillar working system of combine harvesters of CLAAS LEXION 750,760 TERRA TRAC are considered. On the basis of the conducted analysis of constructions of reaping-machines, sloping chambers, threshing machine, cleaning, system of growing and distributing of uncorn part of harvest shallow, caterpillar working system of combine harvesters of CLAAS LEXION, 750,760 TERRA TRAC, the opportunity of their effective exploitation in the conditions of Podillya region is considered. The findings indicate that using the latter in production conditions will gain positive results, high quality and reliability of work

In order to reduce the adhesion of moist threshed rape mixture and cleaning sieve, a method named “Hot-airflow Cleaning” has been proposed. Firstly, the key factors influencing anti-adhesion property were obtained based on the theoretical analysis. They were temperature, wind speed and fan inclination. Then, based on the single-factor experiments, the proper temperature of the fan was 30-50oC, the proper wind speed and inclination of the fan were 2-4 m/s and 15-45°, respectively. Finally, the fan’s parameters were optimized by Box-Behnken design. The results showed that the optimum technological parameters were temperature of 50 oC, a wind speed of 4 m/s and that fan inclination was 45°. This research could provide a reference for the improvement of cleaning system for rape combine harvesters.

The trend towards taut-wire mooring systems, instead of catenary chains, to anchor floating facilities for offshore exploration requires high-capacity anchoring systems capable of withstanding vertical loading components. Conventional drag anchors have very limited vertical capacity, and this has led to the development of alternative drag-in plate anchors, or vertically loaded anchors (VLAs). VLAs are installed in a similar way to conventional drag anchors, but they are ultimately loaded normal to their plate surface, and thus act like embedded plate anchors. A critical issue in the overall mooring system design is the ratio of the pull-out load to the anchor installation load, and this is termed the performance ratio. The performance of a model VLA was modelled in a geotechnical centrifuge, with particular attention to the performance ratios. Whilst the performance ratios obtained were much lower than expected, the testing proved that VLAs provide a simple and inexpensive alternative to other anchoring systems.
