Komatsu PC30MR-5 SMALL EXCAVATORS
Product Feature
New Engine Technologies
The PC30MR-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
Large service compartment doors and tilting cab platform provide simplified daily inspection and maintenance. Large engine and cooler compartment doors simplify daily inspection and periodic maintenance activities. The operator platform tilts forward providing unimpeded access to hydraulic and engine components for maintenance or repair work.
Minimum Swing Radius
The extra-small swing radius with minimum rear protrusion from the tracks (25mm for PC30MR-5) allows the operator to concentrate on work in confined areas.
