Hami City, roof, roof management, roof Warner electromechanical electromechanical safety observations provided by Warner. Warner Mechanical and Electrical Equipment Co., Ltd. Tai'an City (www.tahnjd.com) Tai'an, Shandong Business League certification of quality companies, with brands such as Warner electromechanical, has a good reputation, honesty, service-oriented "business alliance Service" icon on the page We will be happy to serve you! Roof dynamic mechanical analyzer is Warner Tai'an City Mechanical and Electrical Equipment Co., Ltd. in 1982, since the roof subsidence monitoring equipment, model as: KY-82 type. KY-82-type instrument is mine roof dynamic instrument for measuring changes in the roof rock displacement, measuring the amount of roof and floor closer, closer to the speed of roof management system, to conduct stope pressure prediction, detection of bearing pressure peak bit values, etc. is an essential tool for Mining Pressure observations. Digital convergence meter is one of the main products in Tai'an City, Warner Mechanical and Electrical Equipment Co., Ltd.. Overview JSS30A type digital convergence meter (referred to as convergence meter) is the next generation convergence of electronic digital display meter. Digital convergence meter for measuring the tunnel, from small changes in the roadway, caverns and other projects surrounding rock in any direction between two points, to assess the stability of the roof project management, research projects and support the development of rock deformation law determine reasonable support parameters purposes. Convergence has been recognized as one of the measurements must be measured underground engineering measurement projects. Digital convergence meter domestic first electronic digital micrometer roof pressure prevention equipment, by the former Ministry of Coal Science and Technology Progress Award, has a novel structure, easy operation, high accuracy, small size, light weight, good sealing characteristics. In addition the overall tightness, suitable for harsh environments, the shell is made of aluminum alloy rust, corrosion resistance, high mechanical strength. Construction is the ideal tool for research in engineering measurements. Warner Mechanical and Electrical Equipment Co., Ltd. Tai'an City Official Website: http://www.tahnjd.com/
