The second stage is the early 1940s by the German manufactured flexible Scraper conveyor, it shearers, metal bracket with the realization of the mechanized mining. The scraper conveyor cough
Adapt to uneven floor and level uneven convex bending and other conditions, transference without disassembly, and also the amount of coal
The increases, such as the prevailing model SGW-44 type scraper conveyor is this phase of the representative products. Enter 60 years
Since the emergence of hydraulic support on behalf of, in order to concrete mixing machine of mechanized mining, scraper conveyor developed to the third stage,
Developed a high-power heavy armored cough curved scraper conveyor, such as SGD-630/75 type, SGD-630/180 type and so on
