| Quick Overview: |
Bulk excavation with quarry manners is the Liebherr R 972 Litronic’s role. It weighs 68450-76500 kg, takes buckets from 3.00 to 5.50 m³, and its Liebherr D9508 engine is rated 449 HP with 2750 Nm of torque. Digging depth reaches 7150 mm with 354 kN of force at the bucket.
Contractors put machines like this on large canal cuts, township earthworks and quarry benches, where it loads steadily without the transport and support burden of a true mining excavator. Twin 410 L/min pumps keep cycles quick, a 1140 L tank covers the day, and the AC cabin and GPS come standard.
