9 Crawler loaders in tunnelling
Rear attachments
Rear bumper guards
As a standard feature and in order to protect the rear of the vehicle from accidental collisions in tight spaces during
tunelling. All Liebherr crawler loaders are equipped with bumper guards. At the same time, these bumper guards act as
counterweight, which improves the loading capacity.
3-shank ripper
The massive 3-shank ripper has extraordinary penetrat-
ing and ripping capabilities. Whilst being used in tunnel-
ling, the rear ripper increases the versatility of the crawler
loader. This makes loosening the upper ground surface
layer easy and its removal simple.
