Product Feature

New Engine Technologies

The PC55MR-5 is equipped with a clean engine that complies with the EPA Tier 4 Final emission regulations. The engine uses proven environment friendly technologies such as an exhaust gas aftertreatment system, an electronically-controlled cooled Exhaust Gas Recirculation (EGR) system, and an optimum fuel injection system using a common rail. These technologies, combined with Komatsu’s own electronic control system, minimize environmental impact and improve fuel economy.

Electronic control system

The engine and hydraulic system are optimally controlled according to the operating conditions. The hydraulic loss reductions also help reduce both fuel consumption and environmental impact.

Multi-Function Monitor

Various alerts and machine information are displayed in a simple format. Useful information such as operation records, machine setting and maintenance data are also provided. The operator can easily switch screens.

Efficient and Effective Maintenance

The side opening engine hood and large side cover provide easy access for daily inspections. The cab or platform can be tilted up together with the operator’s seat to gain access for major maintenance or repair work.

Minimum Swing Radius

The extra-small swing radius with minimum rear protrusion from the tracks (140mm for PC55MR-5) allows the operator to concentrate on work in confined areas.
