Komatsu PC 88MR-11 Switchable operation weight mode

The PC88MR-11 is powered by a Komatsu SAA6D107E-2 engine, which meets Tier 4 Final emission regulations and delivers 164 hp/122 kW. The four-cylinder, direct injection engine uses a maintenance-free diesel particulate filter (DPF) and selective catalytic reduction (SCR) to control emissions.

Komatsu’s latest intelligent machine control excavator is designed to help contractors improve productivity and reduce fuel consumption. The PC88MR-11 has all the same features as the PC88MR-10 with the addition of a switchable operating weight mode. Operators can now choose between two modes — performance and standard — to optimize cycle times or increase lifting capacity, depending on the job at hand. Performance mode increases the operating weight of the excavator to 85,065 lbs./38,500 kg for increased digging force, while standard mode retains its 80,060 lbs./36,300 kg operating weight for high travel speeds.

The ergonomic control layout makes it easy for operators to view the work area. The joystick steering provides smooth and precise movement of the machine, while the travel lever allows the operator to move forward or reverse with ease. Operators can switch between work modes with a single button. The display panel shows all critical machine functions and indicates any potential problems with the machine systems.

Ma hydraulics abwino

The hydraulic system on this model has been designed to provide excellent power efficiency. The hydraulic cylinders are used in this model to improve digging speed and reduce fuel consumption. This model also has an idle shutdown system that helps lower fuel consumption and engine emissions by turning off the engine after a certain period of idling. The PC 88MR-11 uses a diesel particulate filter system that works without adding additional fuel consumption or exhaust emissions.

komatsu PC88MR-11

The Komatsu PC 88MR-11 is a very tough wheeled excavator that can get the job done in any work environment. It’s meant for loose, unstable ground like sand and gravel and can work on very steep inclines. Of course, there are other wheeled excavators that do the same job for less, but you’ll end up shelling out more money for something that does basically the same job as this machine.
