圆环链可以在大范围内适应井下工作面运输中出现的变化载荷。输送机占用的空间小,又可以任意地缩短及加长。但至今为止,技术上的关键仍在于链子与链轮的严重磨损,尤其是在出现大的动载荷及冲击时往往会拉断链子,造成很大的危害。 Ring chain can adapt to a wide range of changes in the underground face load load. Conveyor takes up less space, but also can be arbitrarily shortened and lengthened. However, so far, the crux of the technology is still the serious wear and tear on the chains and sprockets, which often cause the chains to be pulled apart when large dynamic loads and shocks occur, posing a great hazard.
