At the centre of it all is the proven Liebherr V12 diesel engine specifically designed to withstand extreme outside temperatures and high altitudes with low atmospheric pressure. Integrating the latest engine management system, the R 9150 B is built for extreme conditions. With fast cycle times in mind, like all other Liebherr mining excavators, the R 9150 B uses a closed-loop swing circuit. The main hydraulic circuit comprises a combination of three main valves fed by three working pumps, providing flexibility of attachment control and force distribution, while allowing full oil flow integration for fast movement and fast cycle times. The machine integrates the Litronic Plus electronic control system, allowing for easy control even when simultaneous movements are required. The patented Liebherr electronic bucket cylinder damping system provides controlled end-cushioning for smooth attachment motions, thus increasing machine productivity. The integration of the electronic control system also enables maximum machine versatility “The R 9150 B’s attachment is equipped with pressure-less boom-down function to enable fast cylinder retraction without the need for pump energy. Intelligent energy management diverts the pump flow during boom lowering, allowing other cylinder motions to operate unimpeded,” explains Kriel. Furthermore, the new R 9150 B comes with the exclusive EVO Bucket Solution with patented Liebherr design to maximise the loading capacity and ensure optimal penetration efficiency. Thanks to the contoured sidewalls and the augmented depth, the EVO Bucket backhoe bucket has a capacity of 8,8-9,6 m³ om this particular model. The bucket takes about four passes to load a 50 t off-highway truck. “Therefore, the new bucket makes the excavator the perfect working partner, in terms of shovel match, for the Liebherr T 236 truck and all other articulated and rigid trucks in the 50 to 100 t class,” says Kriel. Efficiency matters The R 9150 B follows the Liebherr design philosophy of maximising a machine’s performance by improving the efficiency of all individual subsystems. Engineered for easy serviceability, the machine is designed to ensure maximum uptime. Several features speak to that effect. The Liebherr hydraulic technology, in combination with the precision of the electronic control contributes to the and the use of various long reach attachments and specific tools.
