Mining environments push cooling systems beyond what standard components can sustain. Extreme ambient temperatures, abrasive particulate, high-altitude operation, and continuous load cycles demand radiators that are built specifically for the machine and the site — not adapted from a general catalogue. SINRUI has supplied copper radiators to mining fleets across 30+ countries since 2001, with direct-fit replacements for the world's largest haul trucks and excavators..

The CAT 793F's C175-16 engine demands consistent cooling under full payload in some of the world's harshest mining environments. SINRUI's copper fin tube radiator (OEM ref. 335-8380) is manufactured to OEM dimensions for direct installation — no frame modification required. The removable tube design allows individual tube replacement on-site, turning a multi-day core swap into a hours-long field maintenance task.

The CAT 793D remains one of the most widely deployed ultra-class haul trucks in global mining fleets, but OEM replacement lead times and discontinued part numbers leave maintenance teams without a straightforward cooling solution. SINRUI supplies direct-fit replacement cooling tube assemblies and full radiator cores for the 793D (OEM ref. 334-6025) — copper fin tube construction, 4-year warranty, three-week lead time.

Komatsu's haul truck and excavator fleets operate across open-pit copper mines, high-altitude coal operations, and extreme-cold iron ore sites worldwide. SINRUI manufactures copper fin tube radiators for Komatsu 730E, 830E, 930E , 960E, HD465-7, HD785, and 1250-7/1250-8 (PC2169), as well as excavator models including the PC8000 and PC9000. All units are pressure-rated to 50 PSI with a 4-year warranty and standard four-week delivery.
