Two of seven: Crawler excavators complete Gen 8 series

 

Since the beginning of 2019, Liebherr has launched seven crawler excavator models under 50 tonnes.

All the platforms developed and produced by Liebherr-France SAS in Colmar were represented on the Liebherr stand at the Bauma 2019 exhibition. The R 930, the mid-weight model of the series, is a brand new Liebherr crawler excavator for earthmoving works.

The Generation 8 series, which has gone into production at Liebherr-France SAS in Colmar, is made up of seven models ranging from 22 to 45 tonnes: R 922, R 924, R 926, R 930, R 934, R 938 and R 945. The easy to transport, versatile and efficient R 930 crawler excavator is fully compatible with the requirements of customers and operators of 30-tonne machines. The machine has been designed to provide extra comfort and safety, as well as optimum ergonomics and performance.

A special platform

The R 930 which was on display at Bauma 2019 complies with Stage V emission standards and – together with the R 926 – is based on a specific platform developed by Liebherr. The R 926 and the R 930 have an operating weight of between 26 and 36 tonnes and achieve peak power of 150kW and 180kW respectively. The backhoe bucket capacities vary from 0.55m3 to 1.75m3 on the R 926 and between 1m3 and 2.15m3 on the R 930. The R 926 and R 930 models are available worldwide with the relevant engines.

To achieve Stage V emissions standards, the R 926 replaces the Stage IV excavator of the same name that was launched in 2016. The R 930 is a brand new weight category for the crawler excavator series developed and produced by Liebherr-France SAS. This was developed in answer to customers’ needs for 30-tonne excavators. The easy to transport, versatile and efficient R 930 crawler excavator more than meets the expectations of customers and operators.

An extremely wide range of equipment and tools makes the R 926 and R 930 crawler excavators very versatile for earthmoving, levelling, digging, loading and even lifting tasks.

Higher power with lower consumption

The digging forces and tractive forces of the undercarriage and the swing torque of the upper carriage have been significantly increased compared to the previous generation. Thanks to these improvements, the R 926 and R 930 crawler excavators achieve a much higher level of performance on construction sites.

In conjunction with the launch of this new generation of excavators, a new work equipment concept was devised that optimises the load curve and inertia of the swivelling drive in order to reduce fuel consumption.

The R 926 and R 930 crawler excavators are available with a variety of robust X- shaped undercarriage types. The crawler chassis requires zero maintenance. The track rollers are lubricated for life and the automatic central lubrication system makes it possible to maximise both component service life and productivity.

Greatest possible comfort, maximum safety

The operator benefits from an ultra-spacious, temperature-controlled cab. To make work particularly convenient, the excavators have pneumatic seats with vertical and longitudinal suspension and a high resolution, extremely user-friendly 7″ touchscreen. The windscreen can be fully lowered.

LED technology has completely replaced the halogen headlights, increasing the operating life and reducing the electricity consumption – while also dramatically improving the lighting. The range of lighting is available in the form of separate packages, with the high performance LED+ lighting packages also available as an option.

The unobstructed panoramic visibility and the monitoring cameras at the rear and sides ensure maximum safety in the driver’s work environment. The fold-away console makes it easy and safe to access the cab. The certified ROPS cab structure provides robust protection in the event of the crawler excavator tipping over. The rear window serves as an emergency exit on all configuration versions of the excavator. The windscreen and right-hand window are made of tinted laminated glass.

Simplified, safer maintenance work

The machine has been carefully designed to offer even higher standards of safety. The upper carriage is now accessed via a secured access platform (either standard or optional extra depending on the region). Additionally, the entire upper carriage is fitted with non-slip studs and does not have any protruding elements. The R 926 and R 930 crawler excavators also boast a new maintenance concept with maintenance points that can be accessed from the ground. The engine oil, hydraulic oil, fuel and urea levels can be read straight off the display for convenience.
