Key features

Ex db I Mb Flameproof Certification: Prevents ignition of methane and coal dust, ensuring safe operation in explosive underground mining environments.

IP67 Full Sealed Protection: Blocks high-pressure water and fine coal dust, solving premature failure issues on wet, dusty roadheader faces.

IC3W7 Water Cooling System: Maintains stable operating temperature under heavy load, eliminating overheating shutdowns during long tunneling shifts.

55kW 1140V High Power Output: Delivers 1472r/min strong torque with Class H insulation, matching standard underground mine high-voltage systems.

Roadheader Direct-Fit Design: Pre-engineered mounting dimensions for drop-in installation on mainstream tunneling machines without custom modification.

Extended Maintenance Intervals: 3300/4300-hour re-greasing cycle reduces underground service frequency, cutting unplanned downtime and labor costs.

S1 Continuous Duty Rating: Supports 24/7 operation in mine development drifts, ensuring consistent cutting performance through full production cycles.
