Pingyang Heavy Industry 1 new stent put into operation

Recently, Pingyang Heavy Industry's innovative design of PMZ268R flexible mold concrete along the empty roadway hydraulic support and PMZ268/T1/T2/T3 three-type end-laying net bracket was put into production.

PMZ268R bracket is Pingyang Heavy Industries Co., Ltd. Shaanxi pioneering architectural design and manufacture of a type of four groups move from transportable for Gob support equipment, arranged after the end lapper bracket, weighing about 329 tons, the total length of 16. 5 meters. The equipment has the functions of supporting the goaf, isolating the working space and the goaf, autonomously moving the frame and erecting the fixed flexible formwork, which can realize the mechanization and automation of the roadway support, improve the work efficiency and reduce the labor intensity. The three-type end-web net support has a working resistance of 18,000 kN, a maximum of 4.0 m and a minimum of 2.2 m, each weighing about 58 tons.

During the R&D and design period, Pingyang Heavy Industry Technicians quickly entered the intense work after receiving their respective division of labor. Because this type of intelligent walking support equipment is innovative design, and the delivery cycle is relatively short, it brings great challenges to designers. The designer made sufficient preparations at the beginning of the plan, read the relevant materials and books, and communicated with the customer many times, detailed analysis, specific calculations, meeting the needs, and completing in a short period of time. Design work.
