The Sandvik EJC145 prototype serves as the foundation for the TK70H 3.5 m³ diesel powered underground loader. Rated to carry a load of 7000 kg, this loader is perfect for tunnel projects requiring shoveling, loading, and transportation. Its sturdiness allows it to function perfectly in challenging, underground conditions with tunnels of a minimum width of 3 m.
