A road header cuts rock underground where maintenance access is minimal and duty is continuous. Drive motors must deliver massive torque, tolerate dust and moisture, and simply not fail between planned service windows.

Motor roles in this machine

• JMDG — heavy drive duty: Crank-type radial piston construction delivers up to 32,182 N·m with the mechanical robustness underground duty demands. JMDG reference →
• Continuous-load rating: Designed for sustained full-torque operation, not intermittent peaks — the difference that matters in tunnelling schedules.
