Primary Equipment Applications

The K2000E is the engine of choice for the most capital-intensive and demanding machinery in the mining sector:

  • Electric-Drive and Mechanical-Drive Mining Haul Trucks: Providing the colossal torque and power needed to move payloads of 200 tons and more.

  • Large Excavators and Shovels: Delivering consistent high-power output for high-duty-cycle digging and loading operations.

  • Front-End Loaders: Ensuring rapid cycle times and powerful breakout force for material handling.

Core Technologies & Design Advantages

The K2000E integrates proven mechanical strength with intelligent technology to maximize uptime and productivity.

  1. Legendary PT Fuel System with CENTRY Controls: At its heart is the time-tested, mechanically simple Cummins PT® fuel system, renowned for high performance and ease of maintenance. Enhanced with CENTRY electronic controls, it optimizes engine efficiency and integrates seamlessly with advanced electric drive systems (like GE's Statex) to achieve significant fuel savings.

  2. Enhanced Durability for Extended Life:

    • Cummins Prelub System: Pressurizes the engine's oil system before startup, virtually eliminating wear during cold and hot starts and greatly extending the engine's life-to-rebuild interval.

    • Galley-Cooled Pistons: This innovative design reduces piston crown temperatures by up to 100°F (38°C), resulting in enhanced durability, reduced ring wear, and up to 30% longer cylinder life.

    • Fillet-Hardened Crankshaft: Built with a smaller bolt circle and rolled threads for exceptional strength to withstand extreme loads.

  3. High-Altitude Performance: The engine's two-stage turbocharging system is specifically engineered to maintain full-rated power at extreme altitudes, delivering reliable performance in mines located as high as 12,000 feet (3,658 meters).

  4. Global Support and Warranty: Backed by Cummins' worldwide service network and a comprehensive warranty. The base coverage includes full protection for the first year, with extended options like the Encompass protection plans available to match any mining operation's needs.
