The single hydraulic props for mines exported to Spain this time were independently developed and produced by China Coal Group Intelligent Machinery Factory. The products have been innovatively improved to overcome the defects and problems of the DZ (piston) single hydraulic props and have large working resistance. , Light weight, long service life, large working stroke, low cost of use, convenient operation, wide range of use and good stability, and many other advantages. Since the product was put on the market, it has been well received by customers at home and abroad. At present, the 57 models of "ZHONGMEI" mining hydraulic prop products independently developed and produced by our group have all obtained the mining product safety mark certificate, and the products are very guaranteed in terms of quality and safety.

The products exported to the Middle East this time include single hydraulic props and hinged roof beams for mining. The hinged roof beam is a kind of mine support equipment, which is combined with various types of single metal pillars to form a metal support. It is a high-strength roof beam for the support of the coal mine in the horizontal and gently inclined working faces. It can realize cantilever support. There is a larger unsupported space between the coal wall and the pillar, which provides conditions for the realization of coal mining mechanization. The hinged roof beams produced by our group are of reliable quality, superior performance, complete technical parameters, and perfect after-sales service. The products are currently exported to many countries around the world and have won unanimous praise from customers at home and abroad.
