KOMATSU D85EX-18 Bulldozer

Interruptor de desconexión de batería

A standard battery disconnect switch allows a technician to disconnect the power supply before servicing the machine.

Comfortable Ride with New Operator Seat and Cab Damper Mounting

The new operator seat is equipped with lumbar support, a tilting adjust function and electric heater. It is easy to adjust to the operator's shape and various working conditions and provides comfortable operation. The standard heated seat makes it possible to work comfortably in the winter.

Tanque DEF de fácil acceso

Located at the right side of the fuel tank, and is accessible from ground level. A convenient sight gauge is also provided.

Sistema de postratamiento de vehículos pesados

This new system combines a Komatsu Diesel Particulate Filtrar (KDPF) and Selective Catalytic Reduction (SCR). The SCR NOx reduction system injects the correct amount of DEF at the proper rate, thereby transforming NOx into non-toxic water (H2O) and nitrogen gas (N2).

Cabina ROPS integrada

The D85EX/PX-18 has a strong integrated ROPS cab. High rigidity and superb sealing sharply reduce noise and vibration for the operator and minimizes dust that enters the cab. This provides the operator a comfortable working environment. Also, there is more side visibility because an additional external ROPS structure and posts are not required.

Apagado automático en reposo Komatsu

Komatsu auto idle shutdown automatically shuts the engine down after idling temporarily to reduce unnecessary fuel consumption and exhaust emissions. The amount of time before the engine is shutdown can be easily programmed from 5 to 60 minutes.

Sistema de turbocompresor de geometría variable Komatsu (KVGT)

The KVGT system features proven Komatsu design hydraulic technology for variable control of air-flow and supplies optimal air according to load conditions. The upgraded version provides better exhaust temperature management.

Nueva niveladora eficiente de combustible

The new D85EX/PX-18 is both productive and fuel efficient with the SIGMADOZER ^reg; blade, automatic transmission and new Tier 4 Final engine. The SIGMADOZER ^reg; blade, based on completely new digging theory, dramatically increases production. This bulldozer significantly improves fuel efficiency compared to a conventional model.

Nuevo motor Tier 4 Final

The Komatsu SAA6D125E-7 engine is EPA Tier 4 Final emissions certified and provides exceptional performance while reducing fuel consumption. Based on Komatsu proprietary technologies developed over many years, this new diesel engine lowers nitrogen oxides (NOx) and particulate matter (PM) by more than 90%, compared to Tier 3 levels. Through the in-house development and production of engines, electronics, and hydraulic components, Komatsu has achieved great advancements in technology, providing high levels of performance and efficiency in virtually all conditions.

Sistema de Monitoreo de Vista Trasera

The operator can view directly behind the machine on the color monitor panel.
