This article discusses ways to increase productivity scraper units. More detail the economic and mathematical model scraper trains, reflecting the peculiarities of its process cycle and structure formation of its operating costs. One of the ways to improve the technical and economic indicators scraper units is to increase the traction engine efforts. Through the implementation of the maximum traction scrapers work in the train allows you to increase the volume of soil to be recruited into the bucket. The article compares the results of experiments using the scraper trailed scraper trains and at work with a pusher, which showed an increase in train performance by increasing the traction and ground transportation speed. Techno-economic performance of the train can also be increased through the use of towing devices reloaded (TSDU) by increasing traction qualities. This article analyzes studies that indicate that the scraper trains to cope with this problem more efficiently than traditional scraper units that allows to intensify the production of earthworks and to improve technical and economic indicators.
