Technical Description
The Komatsu WA500-7 wheel loader is a high-performance machine engineered for demanding production and loading applications, with an operational weight between 74,626 and 75,453 lbs (33,850 to 34,225 kg). It is powered by the Komatsu SAA6D140E-6 turbocharged, aftercooled, 6-cylinder diesel engine delivering 353 hp (263 kW) net power at 1900 rpm, compliant with EPA Tier 4 interim and EU Stage IIIB emission standards. Its rated bucket capacity ranges from 6.8 to 8.2 cubic yards (5 to 6 cubic meters), suited for quarry, aggregates, and heavy-duty material handling work.
The WA500-7 features a large-capacity torque converter with enhanced lock-up and Komatsu SmartLoader Logic for optimal torque control, which improves fuel efficiency and reduces clutch shock during gear shifts. A wide tread and long wheelbase provide excellent stability and maneuverability, complemented by a boom suspension system to minimize spillage. The loader's max dump clearance reaches approximately 10.8 ft (3 m), enabling efficient high-load tipping.
Advanced hydraulic systems, including the Komatsu CLSS (Closed Center Load Sensing) system, along with optional Electronic Pilot Control (EPC) and joystick steering, ensure precise, convenient operation. The wheel loader also includes four-wheel drive, automatic powershift transmission, and robust frames, axles, and driveline components for durability. The cab offers superior visibility and operator comfort with enhanced monitoring systems, making the WA500-7 a reliable, fuel-efficient choice for heavy loading tasks.
