Developed at Liebherr-France SAS in Colmar, the R 930 Tunnel replaces the R 924 Compact Tunnel.
It has been designed to meet as fully as possible the demands of underground construction sites, which are often tight spaces with difficult access. The R 930 Tunnel’s attachment, available in two lengths, features a bearing that can swivel to 2 x 45° angles, allowing the excavation profile to be followed.
Liebherr says the machine’s short slewing radius and powerful, protected LED headlights reduce the risks of collision with construction site personnel and walls. In addition, the cylinders and hoses are specially positioned for maximum protection from potential impacts.
The R 930 Tunnel, which has steel bodywork, can be equipped with the Liebherr quick coupling system, allowing tools to be changed easily and quickly.
Liebherr says a two- or three-tooth ripper bucket ensures high productivity on underground construction sites and the machine can also be equipped with a cutter or hammer to cover a broad area of applications. The R 930 Tunnel’s grading blade allows the creation of a flat ground surface and stabilises the machine on uneven ground. It also protects the undercarriage and crawler drives against impacts from rubble.
The whole ROPS-, FOPS- and FGPS-certified operator's cab, along with its rear and side monitoring cameras, ensures maximum construction site safety. It also has protection for its electronic components.
