Three new 50-tonne G8 crawler excavators from Liebherr prioritize operator experience

Liebherr is expanding its 50-tonne crawler excavator lineup with the R 948 G8, R 952 G8, and R 958 G8 models.

Specialized for earthmoving, the R 948 G8 features an LC chassis, specialist equipment, and optimized powertrain to ensure low fuel consumption without compromising power. 

The R 952 G8 stands out for its versatility. The three different chassis variants, a wide choice of equipment variants, and increased engine power deliver high productivity in the most diverse operating conditions. 

The R 958 G8 was developed specifically for challenging mining work. The machine features a robust S-HD chassis, mass excavation (ME) equipment, and special options for optimizing performance in mining operations.

New excavators built for durability

Designed with the most challenging conditions in mind, the models feature reinforced structures made from high-strength steels and steel castings. The entire construction of the machines is designed specifically to maximize operational readiness and minimize downtime. They are also designed to keep maintenance ultra-simple: with an easy-to-reach platform for accessing the engine, secure access points, and an automatic central lubrication system, which is integrated into the human-machine interface. The lubrication concepts are automatically adapted for maximum protection and durability of the components.

Equipment options and Liebherr technologies available on the new G8 excavators

Liebherr offers a wide choice of equipment options and chassis configurations that enable every machine to adapt to the precise requirements and the specific operation in question. The hydraulic systems are based on Liebherr Technology Positive Control and guarantee fast, sensitive, and harmonized movements.

New assistance systems support the machine operators in their daily operations. Liebherr Power Efficiency (LPE) helps to reduce fuel consumption by up to 10 percent without compromising on performance. 

The Bucket Fill Assist (BFA) system automates the process of filling the bucket in order to maintain productivity levels in operation over the long term. As well, the Modetronic function adjusts the machine parameters to the requirements of every application to ensure optimum performance, whatever the operating conditions.

The models are fitted with an integrated passive 2D control system as standard, which was developed in collaboration with Leica Geosystems. This system is complemented by a built-in, dynamic weighing system. The system provides 500 machine hours as standard to facilitate precise and controlled loading. A 3D control solution is also available as an option, which can be expanded with semi-automated functions to further increase precision and productivity.

Ergonomic controls inside the cab ensure all-day comfort 

The new models are fitted with the latest generation of Liebherr emCAB operator cabins and the INTUSI human-machine interface. This combination ensures operation is intuitive and customizable thanks to carefully designed ergonomics and simplified access to the most important machine functions. The layout of the control elements has been optimized, which, together with the overall design, ensures operators can clearly see the controls and can reach them quickly. This helps to reduce fatigue throughout the working day. Ultra-precise electric joysticks ensure work movements are controlled with smoothness and precision, even in the most challenging fields of application.

With camera assistance systems as standard, the new product line improves the operator's view of the working area for increased safety. Available as an option, Skyview 360° provides a complete all-round bird's-eye view. Safer access platforms, clear views of key operating fluid levels, and accessible refuelling and filling solutions further optimize the safety and efficiency of daily operations.
