Product Features and benefits:
Increased Horsepower
Benefit from the enhanced performance of the excavator’s high-performance engine, certified with EPA Tier 4 Final emissions, delivering increased horsepower (+7 hp). The machine ensures low operating noise and easy serviceability of emissions components.
Engineered for Long Life
Designed to be a long-term part of your fleet, the excavator features a sturdy undercarriage, robust under guards, and the use of thick, high-tensile-strength steel plates throughout the boom and arm structures.
Quick Cycle Times
Ideal for heavy-duty projects, the excavator boasts dual swing motors and an arm quick return circuit, ensuring fast cycle times even under heavy loads.
Easy to Move
Transporting the PC650LC-11 between job sites is convenient, requiring less disassembly to meet transportation weight requirements. The counterweight removal during movement doesn’t necessitate a crane, contributing to lower transportation costs.
Simplified Maintenance
Enjoy ease of serviceability with latched service access doors and grouped service points. The Tier 4 Final emission system diagnostics monitor up to 167 vehicle parameters, notifying you when and where maintenance is required, saving time and money on repairs.
Cost-Saving Hydraulic Efficiency
The excavator achieves increased hydraulic efficiency and reduced fuel consumption with a larger bucket return piping size, reducing hydraulic back pressure in the bucket circuit to match the machine load to hydraulic pump output.
Operator Comfort
Prioritizing operator comfort, the excavator features a quiet cab with less vibration, auto climate control, adjustable armrests, and a rearview camera monitoring system. Mounted work lights and a skylight improve visibility upward and in low-light working conditions.
Advanced Telematics Technology
Utilize advanced telematics technology to keep track of your machines and monitor productivity with free, state-of-the-art remote monitoring services.
Service and Support
Protect your investment with complimentary factory-scheduled Komatsu Care maintenance for the first three years or 2,000 hours, whichever occurs first.
