Equipped with on-board AC variable-frequency speed regulation and rack-pinion travelling mechanism, the machine adapts to working inclinations up to 35°. Optional drum diameters are 2000/2250/2500/2600 mm with two web-depth options (800 mm & 865 mm); drum rotating speed is 31 r/min, and sumping depth reaches 300 mm when paired with φ2000 mm drums for outstanding coal breaking and floor cleaning performance.Powered by standard 3300 V high-voltage mine power supply, the machine weighs about 86 tons and works with heavy-duty scraper conveyors SGZ800, SGZ900 and SGZ1000. Integrated intelligent functions such as remote communication, memory cutting, one-key start-stop and fault diagnosis make it a flagship unit for large-scale automated mining in smart modern mines.

1. Intelligent electric control & comprehensive safety protection
Stable AC variable-frequency speed regulation is paired with multi-level protection, fault diagnosis and historical data storage. Functions including remote data transmission, memory cutting, remote control and one-key start-stop fully satisfy smart mine automation demands; key operating parameters are displayed in Chinese for intuitive monitoring. Each cutting motor is fitted with a clutch and elastic torque shaft to absorb overload impact and prevent rigid damage of motors and transmission parts.
2. Robust structure & convenient maintenance
Split straight ranging arms are interchangeable left-to-right for higher spare-part versatility. Ranging-arm housings are cast from imported special steel exclusive for shearers to resist abrasion and heavy impact. The frame is fastened by hydraulic pull rods and high-strength bolts for excellent structural rigidity. Imported wear-resistant materials are adopted for guide shoes; triple gear pumps supply oil centrally to lift two drums synchronously with quick response.
3. High-power heavy-duty performance for thick-seam high output
946 kN strong traction supports stable operation on slopes up to 35°. Multiple large-drum sizes and two web-depth choices plus 300 mm sumping depth remove residual floor coal and reduce manual cleaning work. Low-speed high-torque drum output boosts hard-coal breaking efficiency and lump coal yield.
4. Excellent system compatibility with face equipment
Factory-matched with heavy-duty SGZ-series scraper conveyors without major site reconstruction. 3300 V high-voltage power input fits mainstream high-voltage power grids of large domestic and overseas mines. Gradient multi-model lineup allows customized selection according to local seam thickness, hardness and inclination.
5. Full-cycle overseas technical support
We tailor machine configuration and drum specifications based on local seam conditions, power supply and conveyor models; deliver integrated mining face solutions, on-site commissioning, intelligent operation training and long-term supply of genuine wear-resistant spare parts worldwide.
