小松 PC58-8 Water Tank

The Komatsu PC58-8 is a classic mini-excavator that excels in small-to-medium earthworks, municipal construction, and confined-space operations. Due to the compact engine compartment layout and high thermal load inherent in mini-excavators, the radiator—as the core of the cooling system—plays a critical role; its heat dissipation efficiency directly determines whether the engine can maintain a stable operating temperature during prolonged, high-intensity work. We offer a high-quality radiator specifically designed for the PC58-8, featuring a reinforced structure engineered to effectively resolve common issues such as overheating and frequent coolant boiling. **Product Technical Specifications** **Compatible Models:** Komatsu PC58-8 / PC56-8 series mini-excavators. **Core Material:** Features a premium aluminum alloy core with high thermal conductivity. The surface undergoes anti-oxidation and anti-corrosion treatment, significantly extending service life in humid, muddy, and dusty environments. **Structural Features:** * **High Vibration Resistance:** Structurally reinforced to withstand the high-frequency vibrations associated with excavator travel and slewing. Welded joints between side plates and cooling tubes are specially strengthened to effectively prevent cracking and leakage caused by vibration. * **Efficient Flow Channels & Fins:** Designed with wide flow channels to minimize coolant circulation resistance. The spacing of the cooling fins is precision-optimized using fluid dynamics principles, ensuring high heat exchange efficiency while resisting dust accumulation. * **Easy Maintenance:** The fin arrangement facilitates daily cleaning and dust removal using low-pressure water sprays or compressed air, ensuring sustained cooling performance. * **Precise Fitment:** Manufactured in strict accordance with Komatsu OE specifications. Inlet/outlet diameters, mounting points, and fan shroud attachment holes align perfectly, allowing for quick, "plug-and-play" installation without modifications. **About Us** Guangzhou Jianming Machinery Equipment Co., Ltd. is an expert in the field of mechanical power systems and components, backed by 20 years of solid practical experience.
