Liebherr expands machine control to Gen 8 crawler excavators

Aug 25, 2023

Liebherr is extending its range of Leica Geosystems machine control options for its Generation 8 crawler excavators.

The R 922, R 924, R 926, R 928, R 930, R 934, R 938 and R 945 models are now available with 2D “3D-ready” and 3D semi-automatic machine control systems. The 2D “3D-ready” passive machine control system is also offered for these models.

All machine control components from Leica Geosystems are installed during the production process and the customer receives a pre-calibrated machine. This avoids the downtime required due to aftermarket installation.

Depending on the situation and requirements, Liebherr offers the right machine control system for every application. With a passive system, machine operators must follow the indications on the display in the cab and operate the machine themselves to complete the job.

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.

Productivity can be significantly increased by using a semi-automatic machine control system. Work can also be carried out much more precisely over a longer period, reducing time-consuming and cost-intensive reworking.

Generation 8 excavators with a passive machine control system can be retrofitted with a semi-automatic system via a corresponding software package at the customer’s request if they are equipped with a Master 5 Premium.

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, removal and 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.

The 2D control system can be upgraded to a full 3D machine control system at any time.

Machine control systems are increasing in importance across a variety of construction projects. They offer significant added value to operators, companies and the environment and enable the operators to use their machines even more productively and precisely.

The consistent use of sensors and software provides the operator with real-time information, which in turn optimizes work processes in terms of time and cost thanks to the ability to automate functions. Waiting times for surveyors are shortened and the need for control measurements on the construction site is reduced.

As well, machine control improves safety on site, as fewer people are needed in the direct vicinity of the machine. The operator’s workload is also reduced, which prevents driver fatigue and the associated susceptibility to errors.
