The Komatsu WA470 wheel loader is a high-performance machine designed for a variety of heavy-duty applications. Here’s a detailed description of the WA470 wheel loader:
- Puissance du moteur: The komatsu WA470 is equipped with a powerful Komatsu SAA6D125E-7 engine that delivers a gross power of 204 kW (273 HP) at 2000 rpm and a net power of 203 kW (272 HP) at 2000 rpm.
- Capacité du seau: The bucket capacity ranges from 3.6 to 5.2 cubic meters (4.7 to 6.8 cubic yards), allowing for efficient material handling.
- High Productivity and Low Fuel Consumption: The komatsu WA470 features a high-performance engine with an electronic heavy-duty common rail fuel injection system, providing optimal combustion of fuel and fast throttle response. The machine also includes a dual-mode engine power select system, allowing operators to choose between E mode for maximum fuel efficiency and P mode for maximum power output.
- Transmission: The WA470 comes with an automatic transmission with a shift timing select system, offering manual shifting or two levels of automatic shifting (low and high). An optional lock-up torque converter is available for increased production efficiency and reduced cycle times.
- Système hydraulique: The komatsu WA470 utilizes a variable displacement piston pump combined with the Closed-center Load Sensing System (CLSS), which delivers hydraulic flow as required by the job, minimizing waste and contributing to better fuel economy.
- Environnement de l'opérateur: The WA470 offers a comfortable operator environment with features such as a fully air-suspended operator station, low noise design, and a rear view camera system. The machine also includes a new monitoring system with Electronic Pilot Control (EPC) standard and an EPC-Multifunction lever (option).
- Reliability and Maintenance: The WA470 is designed with reliable Komatsu components, a sturdy main frame, and maintenance-free, fully hydraulic, wet disc service and parking brakes. The machine also features a cation electrodeposition process for primer paint and a powder coating process for the main structure paint.
- Environmental Harmony: The WA470 is EPA Tier 3 and EU Stage 3A emissions certified, with low exterior noise and low fuel consumption.
- Dimensions and Performance: The Komatsu WA470 has a wide tread of 2300 mm and a long wheelbase of 3450 mm, providing outstanding stability. It also features a 40° steering articulation, making it extremely maneuverable in tight spaces.
- Capacités de recharge de service: The Komatsu WA470 has a fuel tank capacity of 413 liters and a hydraulic system capacity of 173 liters.
The Komatsu WA470 wheel loader is designed to deliver a perfect blend of performance, comfort, and fuel economy, making it suitable for a wide range of applications.
