Komatsu PC88MR-10 SMALL EXCAVATORS
Product Feature
Komatsu Diesel Oxidation Catalyst (KDOC)
The new Komatsu Diesel Oxidation Catalyst (KDOC) has an integrated design that does not interfere with daily operation. This smart and simplified system removes soot using 100% "passive regeneration" without the need for a Diesel Particulate Filter. The KDOC is a simple design and does not have a scheduled service interval like a DPF and is designed for long life with no scheduled maintenance required. For owners, this means lower owning and operating costs due to less complexity and seamless operation.
Newly designed Variable Flow Turbocharger
A newly designed variable flow turbocharger features simple and reliable technology that varies the intake airflow. This provides optimum air flow under all speed and load conditions producing cleaner exhaust gas without sacrificing power and performance.
Efficient Hydraulic System
The PC88MR-10 uses a Closed-center Load Sensing System (CLSS) that improves fuel efficiency and provides quick response to the operator's demands.
High Rigidity Work Equipment
Booms and arms are constructed with thick plates of high tensile strength steel. In addition, these structures are designed with large cross-sectional areas and large one piece castings in the boom foot and the boom tip. The result is work equipment that exhibits long term durability and high resistance to bending and torsional stress.
Swing Boom
The swing boom allows the PC88MR-10 to work where a standard boom excavator could not.
Rear View Monitoring System
The operator can view the rear of the machine with a color monitor screen.
Standard Blade
Every PC88MR-10 comes standard with a 2332mm 7'7" blade. A wide angle blade is also available as an option.
Pattern Change Valve Standard
A pattern change valve is conveniently located below the cab, making switching from excavator controls to backhoe controls quick and easy.
