NEW MINING EXCAVATOR

Powerful model increases performance in quarry and mining applications

Typically, large machinery is used for high-volume digging when the top priority is moving mass amounts of material quickly. Another reason is completing the job in the most efficient and cost-effective manner. Komatsu Senior Product Manager, Mining Support Equipment Joe Sollitt said companies can better achieve both objectives with the new 200-ton-class PC2000-11 excavator that delivers increased horsepower, compared to the Dash-8 model it replaces.

“Customers told us they want better multifunction performance and productivity than the previous model and the competition,” Sollitt said. “With more available engine horsepower, we were able to increase pump absorption and re-engineer the engine-pump-control logic. In combination with a more efficient hydraulic system, the PC2000-11 can load out more material per shift.”

The upgraded excavator has four working modes to tailor machine performance to operating conditions and maximize production and/or efficiency. Among them is an all-new Power Plus (P+) mode that increases productivity up to 12 percent while moving more material per gallon of fuel burned.

Greater reliability, durability

Sollitt emphasized that Komatsu designed the PC2000-11 for greater reliability and durability. It has thicker, stronger boom plates and castings that are highly resistant to bending and torsional stress. The center and track frame were strengthened, and the excavator has larger diameter carrier rollers for extended service life.

“No stone was left unturned when designing this new model. The work equipment and superstructure were engineered to withstand the most demanding applications, and service life of the undercarriage components has been extended. A ground-level service center is standard,” said Sollitt. “The PC2000-11 maintains the power module design that service technicians have grown to love. It provides low noise levels in the cabin, excellent accessibility to major components and reduced labor hours when it comes time for planned overhaul.”
