INTRODUCTION
1.1 Foreword

The HS 845 HDhydraulic excavator with the Litronic control system sets new standards in excavator
design.
• 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, providing the ideal excavator for any
task.
• For the operator this means greater efficiency and lower costs, as fewer machines are needed.
• The Litronic 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.
Improvements to the previous model include the modular construction of the rear counterweight,
the self-loading and self-erecting system and the considerably faster and more effective Litronic
control.
