Liebherr's R 930 Tunnel has been designed with underground construction and quarrying in mind, specifically the tight spaces and difficult access they present. It replaces the R 924 Compact Tunnel to allow for high-level performance in all types of underground applications, says the company.
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. The machine’s short slewing radius and powerful, protected LED headlights can 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, thus limiting damage to them. The R 930 Tunnel has steel bodywork, making it a robust machine which can be equipped with the Liebherr quick coupling system.
