Liebherr has expanded its crawler excavator portfolio in the 50-tonnes class with the R 948 G8, R 952 G8 and R 958 G8 models. 

The manufacturer describes the new machines as combining a robust design, outstanding performance, the new emCAB operator’s cab, and state-of-the-art assistance and machine technologies.

The R 958 G8 (pictured above) was developed specifically for challenging mining work. The machine features a robust S-HD chassis, mass excavation equipment and numerous specialist options for optimising performance in mining operations.

The R 948 G8, designed for earthmoving works, features an LC chassis, specialist equipment and optimised motorisation to ensure low fuel consumption without compromising on power.

The centrepiece of the series is the R 952 G8, which Liebherr hails as a stand-out for its exceptional versatility.

All three models feature reinforced structures made from high-strength steels and steel castings.

The entire construction of the machines is designed specifically to maximise operational readiness and minimise downtime, according to Liebherr.

Maintenance is aided by an easy-to-reach platform for accessing the engine, secure access points and an automatic central lubrication system. The lubrication concepts are automatically adapted for maximum protection and durability of the components.

New assistance systems support the machine operators in their daily operations. LPE (Liebherr Power Efficiency) helps to reduce fuel consumption while the Bucket Fill Assist (BFA) system automates the process of filling the bucket.

Parallel to this, the Modetronic function adjusts the machine parameters to the requirements of every application to ensure optimum performance.

The new models are fitted with the latest generation of emCAB operator’s cabins.

Liebherr said the layout of the control elements had been optimised, ensuring operators could clearly see the controls and reach them quickly.

Ultra-precise electric joysticks ensure work movements are controlled with smoothness and precision.
