Closing Recommendation
Both are heavy, capable loaders, so the choice depends on how your work is spread out and what support you need behind the machine. Choose the Komatsu WA480-6A when you run machines across many sites and need fast, wide parts support, because its strong engine power and breakout force handle mining and construction loads well. Choose the Liebherr L566 when your loader works from one fixed base like a cement plant or port, because its smooth hydrostatic drive and higher speed suit steady, repeat cycles. So match the machine to your work: Komatsu for spread-out sites needing wide parts support, Liebherr for fixed-base cement and port work.
