THE Liebherr R 930 Tunnel excavator has been launched.
The machine replaces the R 924 Compact Tunnel and is designed to allow ‘high-level performance’ in all types of underground applications.
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 added that the short slewing radius and LED headlights ‘considerably reduce’ the risks of collision with construction site personnel and walls.
The cylinders and hoses have been positioned for ‘maximum protection’ from potential impacts. The R 930 Tunnel has steel bodywork and can be equipped with the Liebherr quick coupling system.
A Liebherr two or three-tooth ripper bucket is said to ensure high productivity on underground sites. The R 930 Tunnel can also be equipped with a cutter or hammer to cover a broad area of applications. The model’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.
Additional safety features include a ROPS, FOPS and FGPS-certified cab, along with rear and side monitoring cameras.
