With an operating weight of over 660 tonnes, the R 996 B crawler excavator is the flagship of the Liebherr hydraulic excavator fleet. Its enormous direct excavation force, its reliability and its long lifetime guarantee high performance at low operating costs. The R 996 B is modular in design. All its assemblies can be inexpensively transported by low-bed truck or by ship and mounted in the mine. In addition, the modular design minimises downtime for maintenance or replacing components.
