Komatsu PC88MR-8 Hydraulic Excavator Bridges the Gap

The 9.2 ton class (8.4 t) unit bridges the gap between “compact” and “construction” -sized units.

The 9.2 ton class (8.4 t) unit bridges the gap between “compact” and “construction” -sized units.

The Komatsu America Corp. PC88MR-8 mid-sized hydraulic excavator is designed to bring increased production and added operator comfort to contractors in a wide variety of construction, utility, landscaping and other excavating applications. The 9.2 ton class (8.4 t) 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 Web site 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.

Key features of the PC88MR-8 include:

• Enhanced Comfort and Ease of Operation

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 strength and helps prevent mud and debris build-up, saving the operator time when cleaning the machine.

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 7-in. color monitor for easy viewing of machine functions and monitoring systems.

Every PC88MR-8 also is equipped with a control pattern change valve so the operator can choose either “backhoe” style or “excavator” style controls to match his personal preference.

• Power and Performance

The PC88MR-8 gets its power from a Komatsu Interim Tier IV, 65 hp (48.5 kW) diesel engine.


It 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, according to the manufacturer.

The PC88MR-8 has an operating weight of 18,558 lbs. (8,418 kg) and features a maximum digging depth of 15 ft. 2 in. (4.6 m), with a maximum reach of 23 ft. 5 in. (7 m). The standard auxiliary hydraulic system flow of 5.3 to 33 gpm (20 to 125 Lpm) can be easily changed from single direction flow to bi-directional flow providing many hydraulic attachment options.

• Value

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 also are five working modes to match hydraulic power to the job. 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.

• Service and Maintenance

To simplify maintenance, Komatsu equipped the PC88MR-8 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.

• Peace of Mind

Every PC88MR-8 is backed by a Komatsu 3 year/3000 hour warranty. It’s also loaded with standard features like lockable compartments with single key access, travel alarm, and neutral engine start system.
