Liebherr has launched its new R 930 Tunnel crawler excavator to markets across the world.
The model – which replaces the R 924 Compact Tunnel – was developed at Liebherr-France SAS in Colmar, France. Liebherr says it has been designed to meet the demands of underground construction sites, which often present tight spaces with difficult access.
The R 930 Tunnel’s attachment, available in two lengths, features a bearing that can swivel to two 45° angles, allowing the excavation profile to be followed. The machine’s short slewing radius and LED headlights reduce the risks of collision with construction site personnel and walls.
The R 930 Tunnel has steel bodywork and can be equipped with the Liebherr quick coupling system, which allows tools to be changed easily. it can also be equipped with a cutter or hammer to cover a broad area of applications.
Liebherr says that the machine’s grading blade allows the creation of a flat ground surface and stabilises the machine on uneven ground, as well as protecting the undercarriage and crawler drives against impacts from rubble.
The R 930 Tunnel’s operator’s cab is said to be equipped to withstand dusty environments on underground sites.
