Abstract

The paper discusses specific features of crabbing effects in gantry coal reloaders used at various industrial operations, including the metallurgical ones, and it analyses the movements of the gantry crane support columns under the impact of uneven loading. The process of uneven loading of the gantry coal reloaders is studied with the aim of improving their operating efficiency. The specific nature of the gantry coal reloader’s operation implies that it not only lifts and lowers material, but also moves it by rails along the entire length of the coal storage area, which is typically quite extensive.

Keywords
