MG2×200/910-WD Series AC Electric Haulage Shearers
MG2×200/910-WD series AC electric haulage shearers are core equipment for fully-mechanized mining in medium-thick coal seams. The product line also includes MG2×160/740-WD and MG2×125/600-WD, available in low-profile and high-profile versions for different mining heights. The flagship model MG2×200/910-WD offers mining heights of 1.4–2.7 m (low-profile) and 1.4–3.0 m (high-profile) to fit most medium-thick coal faces.

The product line also includes MG2×160/740-WD and MG2×125/600-WD, available in low-profile and high-profile versions for different mining heights. The flagship model MG2×200/910-WD offers mining heights of 1.4–2.7 m (low-profile) and 1.4–3.0 m (high-profile) to fit most medium-thick coal faces. Installed power reaches 910 kW, haulage speed ranges 0–8.9 m/min and haulage force hits 522 kN. Adopting on-board AC variable-frequency speed regulation plus rack-pinion haulage, the machine runs smoothly and handles working inclinations up to 45°. Three drum diameters (1300/1400/1600 mm) and two web depths (630 mm / 800 mm) are optional; drum rotating speed is 51 r/min, and sumping depth reaches 290 mm when fitted with φ1400 mm drums for high coal breaking and loading efficiency.Compatible with mine power supplies of 1140 V and 3300 V, the machine weighs about 41 tons and works seamlessly with SGZ730, SGZ764 and SGZ800 scraper conveyors. The low-profile frame height is only 855 mm with ample coal-pass height to avoid blockages, making it ideal for large-scale mining in inclined coal seams and variable-height working faces.

Multiple models for flexible mining-height coverage
Three machine variants with low/high-profile frames cover mining heights from 1.3 m to 3.0 m for thin and medium-thick seams. Low-profile units suit narrow working faces while high-profile versions boost output in thicker seams.
High power and strong traction for stable inclined-face operation
522 kN haulage force supports slopes up to 45° without slipping or sliding. Infinitely variable AC frequency speed control (0–8.9 m/min) enables steady low-speed cutting in thin seams and fast high-yield mining in thick seams.
Customizable drums and excavation parameters
Optional drum diameters and web depths paired with 290 mm sumping depth clear residual floor coal and cut manual cleaning work. Scientific pick arrangement produces uniform coal lumps and smooth loading to reduce conveyor blockages.
Compact frame with excellent coal-pass performance
Low-profile frame height of 855 mm and coal-pass height of 295 mm keep material flowing smoothly in confined spaces. The 2318 mm ranging arm and 7530 mm swing center distance expand cutting coverage and raise coal recovery at face corners.
Wide compatibility for efficient face coordination
Factory-matched with mainstream SGZ-series scraper conveyors without extensive site reconstruction; dual-voltage compatibility (1140 V / 3300 V) fits domestic and overseas mine power grids for easy international deployment.
Heavy-duty wear-resistant design for low downtime
Rack-pinion haulage resists impact and abrasion in dusty heavy-load coal mine environments. Reasonable 41-ton weight balances mobility and stability, with well-arranged service points for convenient routine maintenance.
Full-cycle overseas technical support
We customize frame profile and drum specifications according to local seam thickness, dip angle and power supply; deliver integrated face matching schemes plus on-site commissioning, operator training and genuine spare-part supply worldwide.
