Introducing the WA270-8, a mid-size wheel loader designed to meet your diverse.
This versatile loader is ideal for lifting, pipe movement, digging, and seamlessly changing attachments on the fly. Compact enough to navigate small spaces yet powerful and responsive to handle tasks typically reserved for larger machines.
Key features include:
- Easy operation with traction control modes, ensuring optimal performance in various conditions.
- Long-lasting brake life facilitated by a simple one-pedal operation, guaranteeing reliability.
- Impressive break-out force, providing the necessary power for demanding tasks.
- Versatility to adapt to changing job site needs, making it a valuable tool for diverse applications.
Product Features and benefits:
Efficient Control with Hydrostatic Transmission (HST): Minimize wheel slippage and enhance tire longevity with a smooth variable speed traction control system integrated into our Hydrostatic Transmission (HST). This system aids operators in maintaining control across various working conditions. The auto-mode feature automatically adjusts without operator input, contributing to load stability.
Versatile PZ Linkage with High Breakout Force: Experience powerful breakout force and stability with our versatile Parallel Z-bar (PZ) linkage. The linkage incorporates a large break-out force and an auto tilt-in feature, simulating a Z-bar. This design promotes efficient material retention, allowing operators to save time and complete jobs faster.
Fuel-Efficient, Powerful Performance: Achieve fuel savings while maintaining productivity with Komatsu’s powerful engine and SmartLoader logic. The system automatically generates sufficient torque for each work phase, reducing fuel consumption without compromising production levels.
Designed for Easy Maintenance: Streamline maintenance tasks with a swing-out, hydraulically driven cooling fan that operates as needed. The inclusion of new wider fin spacing and a programmable auto-reversing function facilitates cleaning. Gull-wing engine doors provide quick, convenient access for daily checks and service items, contributing to overall ease of maintenance.
Single-Pedal Operation for Enhanced Productivity: Benefit from Hydrostatic Transmission (HST) dynamic braking, enabling single-pedal operation. This feature helps reduce the need for periodic service, extends brake life, and enhances overall productivity, especially for novice operators.
Optional High Lift Booms for Increased Versatility: Extend machine reach and broaden application versatility with optional high lift booms, third spool hydraulics, and quick coupler options. These additions empower owners to tackle larger and more diverse projects efficiently.
