| PC88MR-8 mid-sized hydraulic excavator  Komatsu America Corp. announced the PC88MR-8 mid-sized hydraulic excavator designed to bring increased production and added operator comfort to contractors in a wide variety of construction, utility, landscaping and other excavating applications. The eight ton class (8.4 metric tons) unit bridges the gap between "compact" and "construction"-sized units. The PC88MR-8 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 PC88MR-8 is a member of the short-swing radius family, meaning the operator can focus on the work in front and worry less about rear swing impact in confined areas. It accomplishes these tasks while maintaining its high lifting capacity and stability. The X- frame undercarriage provides superior strength and helps prevents mud and debris build-up, saving the operator valuable time when cleaning the machine. The PC88MR-8 gets it power from a Komatsu Tier 3, 65HP 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. The PC88MR-8 has an operating weight of 18,558 pounds and features a maximum digging depth of 15 ft. 2 in., with a maximum reach of 23 ft. 5 in. The standard auxiliary hydraulic system flow of 33 GPM can be easily changed from single direction flow to bi-directional flow to provide superior hydraulic attachment productivity. The PC88MR-8 is packed with high-value, construction excavator features like X-Frame undercarriage, just like Komatsu's larger models. It features the very same cab with viscous isolation mounts and an instrument package with money-saving features like auto-idle, and an "eco" gauge that tells the operator if he's operating at maximum fuel efficiency. There are also five working modes to match hydraulic power to the job, thereby increasing fuel economy further. It also offers the choice of four track systems; rubber track, two steel grouser systems and the Komatsu Road-Liner track system, ideal for use on multiple surfaces. To simplify maintenance, Komatsu equipped the PC88MR-3 with numerous features. Daily inspections are enhanced by the incorporation of wide opening compartments to allow access to the engine, cooling system, hydraulic valve settings, air cleaner, coolant and windshield washer bottles. In addition, maintenance intervals, including lubrication, have been extended to 500 hours—effectively lowering cost of ownership. write your comments about the article :: © 2008 Construction News :: home page |
