The SH321 L-4 is designed for heavy-duty wheel loaders like CAT 992, Komatsu WA900, and Hitachi ZW500 in severe mining conditions. Its increased tread depth and wider running surface provide exceptional wear resistance compared to L-3 patterns, particularly effective in Colombian coal mines and Peruvian copper mines.

The SH321 L-4 offers 30-40% longer service life than traditional L-3 patterns in severe conditions. The increased tread depth provides more usable rubber, while the wider running surface distributes wear more evenly. The high tread pattern density enhances cut resistance, translating to lower replacement frequency.

Yes, the SH321 L-4 is designed for severe conditions in Colombian coal mines and Peruvian gold mines. The increased tread depth provides durability on abrasive coal and overburden. In high-altitude Peruvian gold mines above 4,000m, the robust construction maintains performance despite challenging conditions.

The SH321 L-4 features high tread pattern density that increases load capacity compared to L-3 tires. The wider running surface distributes heavy loads effectively, making it suitable for large wheel loaders handling 15-25 ton bucket loads. Contact our engineering team for application-specific recommendations.

For SH321 L-4 tires in severe mining conditions, we recommend rotation every 400-600 hours due to the extreme loads. Regular rotation ensures even wear across all positions, extending overall tire life. Combine with daily pressure checks and weekly tread inspections for maximum service life.
