The R 928 G8 crawler excavator is a completely new model, developed and produced by Liebherr-France SAS in Colmar. The new model positioned between the R 926 G8 and the R 930 G8 complements the current Generation 8 series, which already includes 7 models with a gross vehicle weight of 22 to 45 tonnes. The modularity of the new Generation 8 facilitated the launch of this new model as its design is based on existing, high-performance components. This new, weight-optimised combination should significantly reduce the transport problems of many customers.
The R 928 G8 has several features in common with the R 926 G8 and R 930 G8: The same superstructure and equipment as the R 926 G8 and the same LC or NLC undercarriage as the R 930 G8. The performance of the R 928 G8 lies between the R 926 G8 and the R 930 G8.
The R 928 G8 crawler excavator rounds off the current range of Generation 8 crawler excavators. It is characterised by high drawbar pull, excellent load-bearing capacity and a large bucket. Its optimised weight also makes it easier to solve earlier transport problems. The R 928 G8 can hold its own with machines that are heavier than the R 926 G8 and lighter than the R 930 G8.
Generation 8: Product of continuous improvement
Liebherr Generation 8 crawler excavators are the result of constant research and improvement work. This new generation is set apart by a new design and architecture. It has been reworked with the aim of creating optimal ergonomics and performance as well as increased comfort and safety.
Generation 8 develops higher tear and breakout forces compared to the previous generation. The torque of the superstructure has also been increased. This means that the new crawler excavators achieve higher levels of performance under site conditions. In addition, a new equipment concept enables the load curve to be optimised and the inertia in the rotary drive to be improved, reducing fuel consumption. The new, robust X-form undercarriages ensure greater stability. The automatic central lubrication ensures a longer service life of the parts and improves the productivity of the machines.
The spacious, air-conditioned work cab is another feature of Generation 8. The operator enjoys a fully retractable front window, a pneumatic seat with vertical and longitudinal damping and an easy-to-use, high-resolution touchscreen. The use of LED technology reduces power consumption and improves lighting quality. The excellent all-round vision as well as the rear and side surveillance cameras maximise safety in the working environment.
The cab is easily accessible thanks to the raisable control unit, the rear window also serves as an emergency exit. In order to improve safety during maintenance work, access to the superstructure and the maintenance platform has been widened and is now located at the side.
Comfort and safety are thus guaranteed over the entire operation cycle of the Generation 8 machines.
