The Hyundai HX505L is a 50-ton class heavy crawler excavator tailored for high-intensity mining and quarry operations. Powered by a high-torque Cummins engine, it generates massive breakout force and maintains stable performance under continuous heavy loads. The advanced main hydraulic system provides efficient power matching, shortening loading cycles and boosting daily throughput. Heavy-duty boom, arm and bucket adopt thick high-strength steel with reinforced welding, resisting impact and abrasion in rocky sites. The reinforced heavy undercarriage offers stable traction on uneven ground. The fully isolated spacious cabin reduces vibration and noise, improving operator comfort for long shifts. It is widely used in open-pit mining, stone quarrying, large-scale earthworks and rock excavation. Compatible with heavy rock buckets and large hydraulic breakers. Reasonable maintenance layout and global spare parts support help reduce machine downtime.
