Liebherr adds machine control to Generation 8 crawler excavators

All machine control components from Leica are optimally installed during the production process and thus the customer receives a pre-calibrated machine. Liebherr notes that downtimes due to post-production installation are avoided with ex works fitment.

With a passive machine control system, machine operators have to follow the indications on the display in the cab and operate the machine themselves to complete the job. Meanwhile, the semi-automatic machine control system provides active support with a semi-automated removal mode. The machine operator must only control the machine’s stick movements and speed via the joystick. The system automatically adjusts the correct movement of all the equipment to create the target profile.

Generation 8 machines with a passive machine control system can be retrofitted with a semi-automatic system by means of a corresponding software package at the customer’s request.

2D or 3D machine control systems from Leica Geosystems provide the machine operator with information about the height and inclination of the machine as well as the corresponding position via the display in the operator’s cab.

While a 2D machine control system is designed for working from flat and sloping surfaces, a 3D machine control system uses reference models and GNSS to guide the machine operator. Through 3D GNSS positioning in conjunction with 3D model data, all information on excavation and removal, as well as the machine’s position on the construction site, is visible in real time.

With the 2D ‘3D-ready’ variant, work can be done immediately in 2D, either passively or semi-automatically depending on the purchased option. A 2D control can be subsequently upgraded to a fully-fledged 3D machine control system at any time.
