Liebherr, an international manufacturer of construction equipment, has expanded its tunnel excavator range with the introduction of its new R 930 Tunnel crawler excavator.

According to the company, the R 930 Tunnel crawler is an excavator that was designed for underground construction sites. It will reportedly replace the company’s R 924 Compact Tunnel.

The R 930 Tunnel’s attachment is available in two lengths and features a bearing that can swivel to 2 x 45° angles, allowing the excavation profile to be followed.

Further, the excavator’s LED headlights will help operations reduce collision risks with construction site personnel and walls, and its cylinders and hoses have been positioned for maximum protection from potential impacts, thereby limiting damage to them.

“The new R 930 Tunnel crawler excavator can be equipped with the Liebherr quick coupling system, which allows tools to be changed easily and quickly,” Liebherr said.

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

Likewise, the excavator is also equipped with a grading blade that can help create a flat ground surface so the machine can be stabilized on uneven ground, thus protecting the undercarriage and crawler drives against rubble impact.
