KOMATSU WA320-8 WHEEL LOADER

Technical Description

The Komatsu WA320-8 is a mid-size wheel loader engineered for versatile material handling and excavation across multiple applications. Powered by a SAA6D107E-3 engine producing 165 horsepower (123 kW) at 2,100 rpm, this Tier 4 Final compliant machine delivers robust performance with reduced emissions. The loader features a parallel-lift linkage with auto tilt-in capability that simulates Z-bar functionality, enabling operators to maximize breakout force and material retention across diverse jobsite conditions. With a bucket capacity ranging from 3.0 to 4.2 cubic yards (2.3-3.2 cubic meters), the WA320-8 accommodates various attachment options for pallet handling, hard digging, and specialized tasks. The dump clearance reaches 9.4 feet (3 meters) at maximum raise, facilitating efficient material discharge. Operating weight ranges from 34,128 to 34,987 pounds (15,480-15,870 kilograms), providing stability and traction control. The machine incorporates Komatsu's fourth-generation Hydrostatic Transmission (HST) with dynamic braking, enabling single-pedal operation and reducing brake wear while extending tire life. S-Mode traction control minimizes wheel slippage in challenging conditions, while SmartLoader Logic optimizes fuel efficiency—reducing consumption by up to three percent compared to previous generations. Advanced operator comfort features, quick coupler options, and multiple hydraulic configurations enhance productivity and operational flexibility across agriculture, waste management, and construction applications.
