Komatsu America Corp. Launches New PC88MR-10 Hydraulic Excavator
Komatsu America Corp. introduces the PC88MR-10 hydraulic excavator. With a net 65.5 HP (48.8 kW), the PC88MR-10 is powered by a 4-valve per cylinder Komatsu SAA4D95LE-6 engine and is EPA Tier 4 Final emission certified.
Komatsu’s Tier 4 Final engines are built on a solid foundation that started in 1996 with the introduction of Komatsu’s Tier 1 engines. The resulting benefit today is a Tier 4 Final engine that is productive, dependable and efficient. This new excavator leverages Komatsu’s leadership in technology and innovation by delivering an environmentally-friendly engine that provides high levels of performance while reducing fuel consumption and operating costs.
With an operating weight between 18,739 lbs. (8500 kg) and 19,290 lbs. (8750 kg), the PC88MR-10 tight-tail excavator features improved efficiency, lower fuel consumption, improved operator comfort and enhanced serviceability. This compact excavator bridges the gap between compact and construction sized excavators for contractors working in a wide variety of construction, utility and landscaping applications.
The PC88MR-10 is equipped with the latest KOMTRAX® remote monitoring technology with data access via the web or via KOMTRAX Mobile on your smart phone. In addition to providing data such as fuel levels, operating hours, location, cautions and maintenance alerts, KOMTRAX® has been further enhanced with a new Operator Identification System which reports key operating information for multiple operators. A new Auto Idle Shutdown function helps improve operating costs by reducing unnecessary idle time. Special features of the new PC88MR-10 include:
Komatsu EPA Tier 4 Final Emission Certified Engine – Productive, Dependable, Efficient
Komatsu’s EPA Tier 4 Final engines are built on the strength of its proven Tier 4 Interim foundation that integrates a Variable Flow Turbocharger (VFT), Exhaust Gas Recirculation (EGR) and a Komatsu Diesel Oxidation Catalyst (KDOC). The KDOC is a simple 100% passive regeneration system that does not require AdBlue®/DEF injection or a diesel particulate filter. The Komatsu EPA Tier 4 Final engine uses an advanced electronic control system to manage the air-flow rate, fuel injection, combustion parameters, and after treatment functions to optimize performance, reduce emissions, and provide advanced diagnostic capability. The result is up to 4% lower fuel consumption with no loss of performance. To ensure product reliability and durability in demanding conditions, Komatsu developed the entire system, including the control software. This control system is also integrated into the machine’s on-board diagnostics systems and KOMTRAX®, Komatsu’s standard telematics system.
Performance
The PC88MR-10 features a maximum digging depth of 15’2” (4615 mm) and a maximum reach of 23’5” (7150 mm). A “swing boom” allows the PC88MR-10 to work in confined spaces so 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 standard auxiliary hydraulic system flow of 33 GPM (125 ltr/min) can be easily changed from single direction flow to bi-directional flow to provide excellent hydraulic attachment productivity. Standard equipment includes a bucket thumb-mounting bracket, auxiliary piping for attachments and a 7’7” (2330 mm) blade that is standard with an available power angle blade option.
There are six working modes to match hydraulic power to the job, thereby further increasing fuel economy. A new enhanced attachment control allows up to 10 attachments to be stored in the monitor panel and two-way attachments can also be operated in Economy Mode. An “Eco Guidance” function helps increase fuel efficient operation. The PC88MR-10 offers the choice of rubber track, steel grouser systems or the Komatsu Road-Liner track system.
