High quality service provider for mining equipment improvement
The friction coefficient under various working conditions is greater than 0.25 (measured by China University of Mining and Technology and Luoyang Mining Machinery Engineering Design Institute as both are greater than 0.28), which fully meets the needs of multi-rope friction hoists.
JB/T12185-2015 underground mine overhead cable friction pad industry standards released by the People's Republic of China Ministry of Industry and Information on April 30, 2015 was drafted by Zhongshi Luoyang Engineering Plastics Co., Ltd.
Disc brakes use butterfly springs to generate braking force and rely on oil pressure to release the brakes. In the braking state, the positive pressure of the brake shoe against the brake disc is determined by the pressure of the working oil in the hydraulic cylinder.
This series of products includes single-cylinder and double-cylinder models with diameters of 2.8m-3.6m. They are used for lifting materials and personnel when sinking shafts in coal mines, metal mines and non-metallic mines. They are special equipment for digging shafts in mines.
