The eight-ton class PC88MR-8 hydraulic zero-swing excavator bridges the gap between compact- and construction-sized units. The unit is equipped with the latest KOMTRAX technology, which sends machine operating information to a secure website utilizing wireless technology. Real-time data including machine-operating hours, machine location and fuel levels are relayed to the web application for customer viewing and analysis. The cab is the same used on a larger unit and features a standard automatic climate control system, pilot-proportional joystick controls with auxiliary hydraulics control on the right joystick and a seven-inch color monitor for easy viewing of machine functions and monitoring systems. Every unit is also equipped with a control pattern change valve so the operator can choose from either backhoe or excavator style controls. The PC88MR-8 gets it power from a Komatsu Interim Tier 4, 65-hp diesel engine, which has an increase of 17 percent more power than the prior model PC78MR-6. It also features increased drawbar pull, faster travel speed, 10 percent more arm digging force and a significant improvement in dozer blade travel to enhance grading and backfill operations. www.komatsuamerica.com
