eDRAGON: Battery-Powered Monorail

A New Generation of Underground Transport

The eDragon is a modern, explosion-proof battery-powered monorail designed for transporting personnel and materials in underground mining. Engineered for quiet, zero-emission, and reliable operation in the most demanding working conditions, it represents a breakthrough in the MineTrans® transport segment.

Thanks to its modular design and configurable drive units, the eDragon combines high tractive force with application flexibility and integration with Becker-Warkop digital systems.
