KOMATSU PC30MR-5 Excavadoras pequeñas
Características del producto
Nuevas tecnologías de motores
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.
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
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.
Radio mínimo de giro
El radio de giro extra pequeño con una protuberancia trasera mínima de las orugas (25 mm para PC30MR-5) permite al operador concentrarse en el trabajo en áreas confinadas.
