Extreme-duty propulsion for continuous heavy haul cycles.

Mining operations demand uncompromising durability under sustained high loads, shock events, and harsh environmental conditions. Sigma Powertrain engineers fully integrated powertrain systems built designed for torque density, structural resilience, and thermal stability.

By controlling the entire propulsion architecture — motor, gearbox design and controls — we maximize uptime, extend component life, and support safe, reliable operation in the most severe duty cycles.
