コマツ（小松製作所） WA 470

As a robust benchmark for heavy-duty operation scenarios, my Komatsu WA470-8M0 Wheel Loader stands out with its powerful performance and intelligent technologies, making it the ideal partner for mining operations, port cargo handling, and large-scale infrastructure projects. Equipped with the Komatsu self-developed SAA6D125E-7 Tier 4 Final engine, it delivers a rated power of up to 204kW (277PS). Combined with a high-pressure common rail fuel injection system and a VGT variable geometry turbocharger, it not only outputs strong power but also reduces fuel consumption by 13% compared to the previous model, fully complying with stringent environmental standards. The 3.6–5.2m³ wide-body bucket, paired with an optimized link mechanism, achieves a maximum tipping load of 17,360kg. The working device’s combined cycle time of 10.1 seconds ensures smooth and efficient loading cycles. The intelligent loader logic system automatically adjusts engine torque based on operating conditions, and with three working modes (E/P/E light), it can be precisely adapted to both heavy-duty excavation and empty vehicle travel. The CLSS closed-center load-sensing hydraulic system works in tandem with the automatic transmission, enabling smooth gear shifts without impact and greatly improving operational continuity. The cab features a ROPS/FOPS safety design. An air-suspended heated seat, combined with an electronically controlled suspension system, effectively filters out vibrations and jolts during operation. Coupled with a low-noise engine and sealed structure, it creates a comfortable and quiet operating environment. The 7-inch LCD monitor displays fuel-saving indicators and equipment status in real time. A standard rearview camera provides 360° all-round visibility, and the remote bucket positioner can memorize three working angles, significantly reducing operational difficulty. The fully hydraulic wet multi-disc brakes feature a maintenance-free design. The upward-opening engine side door and centrally arranged aftertreatment device facilitate easy ground maintenance. Supported by the KOMTRAX remote monitoring system and Komatsu’s global service network, the equipment ensures long-term stable operation.
