KOMATSU PC45MR-5 Excavadoras pequeñas
Características del producto
Nuevas tecnologías de motores
The PC45MR-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.
Sistema de control electrónico
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.
Monitor multifunción
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.
Radio mínimo de giro
The extra-small swing radius with minimum rear protrusion from the tracks (60mm for PC45MR-5) allows the operator to concentrate on work in confined areas.
