Features :- Komatsu Excavators
- PC120LC-6
Since its original introduction, the PC120-6 has set new standards for productivity and control. The improved PC120-6 introduces several outstanding new features to provide the operator with a faster, quieter, and easier-to-service machine.
Cushioned cylinders not only minimize shock but provide fast cycle times.
Windshield wiper is mounted to the cab for better visibility and easier window opening.
Advanced Monitor Features - Self-diagnosis of 119 different problems. - 5 working modes as standard, including breaker mode for maximum productivity. - Active-mode for increased implement speed. - Oil maintenance reminder.
Large undercarriage components are sealed for maximum durability.
Cast steel is used for critical parts on both the boom and arm for increased durability.
Komatsu distributors offer a wide variety of attachments that take advantage of the PC120-6's exceptional versatility.
Large boom cylinders provide maximum lift capacity.
Comfortable Cab - Komatsu's low-noise cab design uses viscous cab mounts for reduced noise and vibration.
Protected Hydraulic Circuit - The cool-running hydraulic system is protected with the most extensive filtration system available.
New Komatsu SAA4D102E-2 turbocharged, aftercooled diesel engine provides an output of 89 HP / 66.2 kW with excellent productivity. This engine is Tier 2 EPA, EU and Japan emissions certified.
