China successfully promoted new AC electric traction shearer

The MG500/1130-WD AC traction shearer, developed by the Xi'an Coal Mine Machinery Plant, has seen extensive production and sales, with over 50 units successfully manufactured and sold. This advanced shearer has been widely adopted in several major coal mining regions across China, including Kailuan, Datong, Huainan, Shandong, Heilongjiang, Sichuan, Gansu, and Shaanxi. In May 2006, the first unit was exported to Russia, marking a significant milestone for the company's international expansion. The MG500/1130-WD model is equipped with cutting-edge technology, featuring a multi-motor drive system with motors arranged laterally, eliminating the need for a traditional bracket. It uses a hydraulic tie rod coupling method, ensuring smooth and efficient operation. The machine is powered by a high-power two-stage four planetary gear system, combined with a planetary reducer for enhanced performance. The rocker arm design includes built-in water cooling, which helps maintain optimal operating temperatures even under heavy loads. The shearer operates using a main and slave macro control mode, allowing for precise and direct torque adjustment. A 10-inch LCD screen provides clear graphical displays, making it easier for operators to monitor and manage the machine’s functions. The electrical system features a high and low voltage sub-cavity layout, improving safety and efficiency. With a rock-cutting hardness capability of up to 10.2 Platts and a climbing angle of 38 degrees, the MG500/1130-WD is well-suited for challenging mining conditions, particularly in areas with high rock hardness, multiple faults, and complex geological structures. Its versatility has made it a popular choice both domestically and internationally. During field testing, the model demonstrated impressive performance, advancing 191.5 meters continuously without interruption, cutting 415 square meters of rock, and increasing coal output by 180,000 tons. It also generated an impressive monthly output value of 81 million yuan, showcasing its efficiency and economic benefits in real-world mining operations.
