Komatsu WA320-8

Komatsu WA320-8 Loader

From agriculture, waste and residential job sites, look to a versatile machine, well-suited to work in multiple applications with easily changing attachments.

  • Easy operation with traction control modes
  • Long-lasting brake life with simple one-pedal operation
  • Impressive break-out force
  • Versatility for changing job site needs

Enhanced control with HST: Help minimize wheel slippage and promote extended tire life with a smooth variable speed traction control system that helps keep your operator in control in virtually all working conditions. Auto-mode automatically adjusts without operator input, helping to keep loads stable.

Versatile PZ linkage plus high breakout force: Powerful breakout force and stability. Parallel-lift linkage with large break-out force and auto tilt-in feature simulates a Z-bar, which promotes material retention, helping operators save time and finish jobs faster.

Powerful performance, low fuel consumption: Save fuel while remaining productive. Komatsu's powerful engine and SmartLoader logic automatically creates enough torque for each work phase, reducing fuel consumption with no decrease in production.

Designed for easy maintenance: Swing out, hydraulically driven cooling fan that runs as needed, with new wider fin spacing and programable auto-reversing function makes cleaning easier. Gull-wing engine doors provide quick, convenient access for daily checks and service items.

Single-pedal operation: HST dynamic braking allows single-pedal operation which helps reduce periodic service, helps increases brake life, and promotes enhanced productivity, particularly among novice operators.

Optional high lift booms: Extend machine reach and application versatility with optional high lift booms, third spool hydraulics and quick coupler options, allowing owners to tackle bigger and more diverse projects.
