The Komatsu WA380 wheel loader is a high-performance machine designed for a variety of applications, offering a blend of productivity, comfort, and economy. Here’s a detailed description of the WA380 wheel loader:
- Potencia del motor: The Komatsu WA380 is equipped with a Komatsu SAA6D107E-1 engine that delivers 143 kW (192 HP) at 2,100 rpm. This engine is both quiet and fuel-efficient, meeting EU Stage IIIA and EPA Tier III emissions regulations.
- Operating Weight and Bucket Capacity: The operating weight of the WA380 ranges from 17,510 kg to 18,570 kg, with a bucket capacity varying from 2.7 to 4.0 cubic meters.
- Hydraulics and Control: The Komatsu WA380 features a Closed-center Load Sensing System (CLSS) hydraulics system with variable-displacement pumps, which allows for precise control of the working gear and ensures smooth movement of the bucket, boom, and attachments. This system also improves fuel efficiency.
- Transmisión: The wheel loader is equipped with an automatic transmission with electronically controlled modulation valve and variable transmission cut-off, providing smooth shifting and optimal power delivery.
- Cab and Operator Environment: The WA380 offers a pillar-less large cab for best comfort and visibility. It includes features such as air conditioning, climate control options, and a deluxe heated, air-suspended seat for operator comfort.
- Maintenance and Accessibility: The Komatsu WA380 is designed for easy maintenance, with features like an Equipment Management Monitoring System, easy radiator cleaning, and centralized oil and fuel filter arrangements.
- Reliability and Safety: The machine boasts high-rigidity frames and loader linkage, wet multiple-disc brakes, and a fully hydraulic braking system. It also includes a ROPS/FOPS cab for operator safety.
- Fuel Efficiency and Performance: The WA380 offers a dual-mode engine power select system, allowing the operator to choose between E mode for maximum fuel efficiency and P mode for maximum power output. The machine also features an Eco indicator to inform the operator when the machine is maximizing fuel efficiency.
- Dumping Clearance and Reach: The long lift arms provide high dumping clearances and maximum dumping reach, making it easy to level loads on the body of a dump truck.
- Komtrax: The Komatsu WA380 is equipped with Komtrax, Komatsu’s tracking system, which allows for remote monitoring of the machine’s location and operation.
This wheel loader is designed to provide high productivity and low fuel consumption, with a focus on operator comfort and ease of maintenance.
