INTRODUCTION:
1.1 Foreword:
The Liebherr drilling rig LB 28 is a machine specially developed for very varied drilling
applications.
• The basic machine
– has been developed for continuous, heavy-duty operation on construction sites,
– is of modular design,
– can be assembled and extended in many different ways, thus making it the ideal equipment for any
task.

task.
• For the operator this means greater efficiency and lower costs, as fewer machines are needed.
• The Litronic VME control system combines the advantages of the most up-to- date
control technology with hydraulic power transmission. It allows functions such as load
limit regulation, low-loss pressure limitation, extensive diagnostic facilities, automated
processes and operating data acquisition.
