Liebherr has launched its R 930 Tunnel crawler excavator, replacing the R 924 Compact Tunnel.

The R 930 Tunnel’s attachment, available in two lengths, features a bearing that can swivel to two 45 degree angles, allowing the excavation profile to be followed.

Liebherr says the machine’s short slewing radius and powerful, protected LED headlights considerably 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 has steel bodywork, making it a very robust machine, ideal for underground applications.

A Liebherr two- or three-tooth ripper bucket ensures high productivity on underground construction sites.

The R 930 Tunnel can also be equipped with a cutter or hammer to cover a broad area of applications.

Its 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.

Safety features include a ROPS-, FOPS- and FGPS-certified operator’s cab, along with rear and side monitoring cameras.
