Komatsu based its all-new PC900LC-11 excavator on the proven PC800LC-8, adding about 10% in operating weight (depending on configuration). That weight, plus the PC900’s 842-horsepower diesel engine (73% more power than the PC800) boosts the big machine’s performance significantly:

  • Up to a 40% increase in productivity
  • 25% more arm crowd force
  • 12% more swing torque

The new counterweight-removal system makes it easier to take 28,000 pounds off the PC900 for transport, and the boom configuration reduces transport height. A new service pass-through area allows easy access to filters, oil level checks and sample ports. Komatsu says major structures, booms, arms and a redesigned revolving frame were engineered to increase longevity.

To improve operators’ situational awareness, tools such as the KomVision camera system come standard on the PC900LC-11. KomVision is a 360-degree monitoring system that uses six cameras for a real-time view of the surroundings. Smart Construction 3D guidance and payload monitoring are available options.

At CONEXPO-CON/AGG 2023, the PC900LC-11 was displayed with Smart Construction Retrofit, an affordable guidance kit that gives operators in the field and managers in the office access to both 2D and 3D design and payload data to help drive accuracy, control load volumes and improve operations. Easily installed by a local Komatsu distributor, this technology upgrade is designed to improve grading performance.
