Komatsu America Corp.’s PC27MR-3 compact hydraulic excavator is designed to bring increased production and added operator comfort to contractors in a variety of construction, utility, landscaping and other applications.
The PC27MR-3 is equipped with the latest Komtrax technology, which sends machine operating information to a secure Web site utilizing wireless technology. Data such as operating hours, machine location and fuel levels are relayed to the Web application for analysis. The Komtrax fleet monitoring system increases machine availability, reduces the risk of machine theft and provides a wealth of other information to drive business efficiency.
Special features of the PC27MR-3 include:
• Operator Comfort
For operator comfort, the PC27MR-3 allows easy entry and egress due to the wide entrance and well placed handholds. A fully adjustable suspension seat with retractable seat belt lessens fatigue and pilot proportional joystick controls with wrist rests permit continuous, comfortable operation.
The PC27MR-3 is a member of the minimum swing radius (MR) family of compact excavators. This enables the operator to focus on the work in front and worry less about rear swing impacts in confined areas. The PC27MR-3 accomplishes these tasks while maintaining high lift capacity and stability.
The PC27MR-3 has an operating weight of 6,460 lbs. (2,930 kg), and features a maximum dig depth of 9 ft. 4 in. (2.8 m). The standard thumb mounting bracket and auxiliary hydraulics simplify hydraulic thumb installation, enhancing the machine’s capability and versatility.
The PC27MR-3 gets its power from a Komatsu engine with a net power of 25.3 hp (18.8 kW). The direct injection engine meets EPA emissions requirements and is fuel efficient without sacrificing power or efficiency. The X-track frame deters the build-up dirt and debris, saving the operator valuable time when cleaning the machine. The single, large diameter swing pin ensures long life and durability of the boom swing mechanism.
• Service and Maintenance
To simplify maintenance, Komatsu equipped the PC27MR-3 with numerous features. The operator compartment tilts up for providing access to the hydraulic components and the back of the engine (starter/alternator). The wide opening engine cover and side covers provide access to daily checkpoints. In addition, the radiator and oil cooler are side by side making them easy to inspect and clean and ensuring only clean, fresh air reaches each component. Extended greasing and service intervals make it easier to schedule maintenance.
