hazardous to work in . In addition to increasing safety , LiReCon also boosts driver comfort and productivity . But it is the ability of the system to work in dangerous environments that the force found most impressive .

Equipped with cameras with real-time video transmission , the Liebherr system displays the work area with different views from varying angles . Microphones track the machine noises , and radio receivers and transmitters ensure a seamless connection to the remote driver . The main monitor uses a high-resolution video signal to provide a comprehensive view of the entire operational environment of the machine . The active person detection system , fitted as an option , identifies persons or obstacles in the work area , further increasing safety , to avoid accidents and prevent damage .
“ LiReCon offers an advanced solution for all Crawler Dozer operations . It ensures complete integration of the machine and visualisation of all relevant machine data . This includes the teleoperation stand , which is a state-of-the-art operator station equipped with all the necessary controls and system information ,” explains Hansjörg Nocker , sales manager at the Liebherr Telfs plant .
Based on their positive experience with the Liebherr PR 726 Crawler Dozers supplied in 2018 , the Austrian Armed Forces collaborated with Liebherr Product Development to come up with a new operational design tailored to their needs . “ The military training ground in Allentsteig is a zone with multiple unexploded munitions , and these have to be removed after military exercises . Up to now , clearing equipment with splinter protection and bulletproof glass have been used . Nevertheless , there was always a risk that the driver could be injured ,” explains Lieutenant Colonel Dirk Wurth from the Office for Armaments and Defence Technology , Engineer Technology Department .
For this reason , the machine design was developed for teleoperation along with a container fully equipped for remote radio control of the machine . “ Using this new design , we can effectively deploy equipment both for dangerous operations on the military training ground and difficult environments in disaster recovery . This also includes driverless support operations over the most difficult terrain , such as landslides or for road clearance with the army corps of engineers ,” noted Wurth .
LiReCon supports a range of remote control configurations . The on-site solution enables remote control of machines without visual contact , while relay stations are available as an option for extended operational range . The system can also be operated via an internet connection . Full integration into the machine control system , ensures that all current and future assistance functions can be used . LiReCon is therefore a foundation element for future device automation .
" LiReCon is notable for its modular design . With the latest upgrade , the control station is even more compact and transportable , enabling seamless integration into a range of plant infrastructures ,” explains Hansjörg Nocker from the Liebherr Telfs plant . LiReCon is a universal cross-sector product . The intuitive user interface allows it to be readily integrated into different Liebherr machines , making it easy to switch between a wide variety of operating units .
In terms of safety , the system has an integrated emergency stop control to stop the machine dead in dangerous situations , as well as special safety functions for LiReCon machines . Data security for
LiReCon is ensured by encrypted data transmission and monitored data packets . It also offers operator certification with various authorisation levels .
With the benefit of Liebherr ' s standard Operator Assistance Systems and increased blade capacities , the Liebherr PR 726 G8 is suitable for both grading with millimetre-precision and for operations demanding pushing performance , for example in road clearance operations .
The electronically controlled operating hydraulics can be precisely tailored to the operating conditions and the driver ' s needs . As a result , the Liebherr development team have been able to integrate intelligent assistance functions and machine control systems . Liebherr Indicate provides the driver with detailed information about the absolute longitudinal grade and cross slope of the machine , together with all the parameters for the Liebherr Assistance Systems . The parameters for the desired terrain can be entered directly into the touch display as target specifications , which then flow in real time into the active blade control . In the case of the Austrian Armed Forces , this can also be carried out from the external LiReCon control station . All Liebherr Assistance Systems have been developed as open systems with a focus on the future requirements of modern digital operations management . •
