1. What is the Coal Mining Machine (SANY medium-thickness coal seam series)?
It is a longwall coal shearer designed for medium-thickness coal seams (SANY series) used for continuous longwall mining. The machine integrates hydraulic, electric and intelligent control systems for reliable cutting, conveying and face operation.
2. Which models and series are available?
Two main product lines are offered: the 710-series (examples: MG250/610, MG300/710, MG300/730) and the 1180-series (examples: MG400/980, MG500/1180, MG550/1355). Model choice depends on mine height, face geometry and production requirements.
3. What mining height ranges and face heights do the machines support?
Depending on model, the series covers typical mining heights roughly from about 1.9 m up to about 5.0 m and a variety of machine-face heights. Exact mining height ranges and face heights are model-specific—refer to the detailed spec sheet or contact sales for the exact values for a given model.
4. What are the main hydraulic system features?
The hydraulic system uses a duplex pump arrangement (large-displacement pump for height adjustment, small-displacement pump for the brake) to reduce power loss. An oil-return pipeline includes a fin-type cooler to keep hydraulic oil temperature below 50°C for stable operation.
5. What electric and control features does the machine include?
The machine features a high-reliability electric system with stratified cable and fluid routing, modular integrated control and inspection cabinets for easy replacement and maintenance, shock-tested electric components, a black-box data recorder with failure memory, and an intelligent self-diagnostic system for fault locating and warnings.
6. What is the quadrant control by frequency converter?
The machine's drive/control strategy uses a quadrant control approach implemented on a reliable frequency converter. This strategy is tuned to handle high-inclination working conditions and was validated by simulated site tests to improve drive performance and stability.
7. How does the gear micro-modification technology improve performance?
Gears are micro-modified according to housing deformation conditions to avoid partial offset loading on tooth faces. This reduces localized wear, balances load distribution across gear teeth and extends gearbox and drive reliability.
8. What measures improve structural accuracy and reliability?
Housings are finish-machined on imported machining centers to ensure tight dimensional tolerances and surface roughness. An imported constant-temperature coordinate inspection center verifies 100% tolerance conformance, ensuring reliable alignment and drive performance.
9. What diagnostics and monitoring capabilities are provided?
A black-box data storage system records operational data and stores failure history for later query. The intelligent self-diagnostic system provides automated fault locating and warning functions to support troubleshooting and preventive maintenance.
10. How does the machine manage drive shocks and stability?
Multi-sensor shock test analytic technology monitors and controls shaft engagement-direction shocks; this reduces impact loads on the drivetrain and improves overall drive stability and component life.
11. What does modularity mean for operators and owners?
High modularity means main components and parts are interchangeable across the series. Owners can reconfigure or replace modules at lower cost to adapt machine performance to different mining conditions, and maintenance/repairs are simplified.
12. What routine maintenance is recommended?
Regular inspections should cover hydraulic oil condition and temperature (ensure cooler functioning), gearbox and drive checks, electrical cabinet and harness integrity, and verification of diagnostic logs. For specific intervals and procedures, follow the manufacturer service manual or consult authorized service.
13. Are spare parts, service and operator training available?
Yes. Spare parts and after-sales service are available through the manufacturer or authorized dealers. Installation, commissioning and operator/maintenance training are typically provided—contact your local SANY representative for details and service packages.
14. What safety features are included?
Safety-related design includes a reliable braking circuit (separate pump), shock-analytic technologies to limit drivetrain impact, and the intelligent diagnostic system for early fault warnings. Site-specific safety systems (e.g., interlocks, emergency stops) should be integrated per mine regulations—confirm with the supplier.
15. How do I get pricing, lead time, warranty and certifications?
Pricing, lead time, warranty terms and compliance/certification details vary by model, options and purchaser location. Contact the manufacturer's sales team or authorized distributor with your site conditions and required configuration for an official quote and documentation.
