AMPER
The AMPER locomotive is a modern traction machine designed for transporting people, equipment, and cargo in underground and surface rail systems. Designed for use in underground mining operations, it meets the requirements of “a” methane explosion hazard levels and Class A coal dust explosion hazard. Compliant with Directive 2006/42/EC and national safety regulations, it ensures reliability and safety in challenging conditions. Its design combines versatility with high efficiency, making it an ideal solution for the mining industry.
