09/13/2022 Active personnel detection for Liebherr wheel loaders receives 2022 VDBUM Award
- Active personnel detection: Assistance system for wheel loaders to prevent accidents
- Assistance system awarded in the “Developments from Industry” category
- Liebherr had its own stand and gave technical presentations at the VDBUM grand seminar
The German Association of Construction, Environmental and Mechanical Engineering (VDBUM) awarded active personnel detection with the 2022 VDBUM Award. Active personnel detection is an intelligent assistance system developed by Liebherr for the Group’s wheel loaders. Dr.-Ing.
In July, the expert jury awarded active personnel detection in the category “Developments from Industry”. Active personnel detection uses sensors and artificial intelligence to automatically distinguish between persons and objects in order to specifically warn the machine operator of an accident that may result in personal injury. If a person moves into the rear area of the wheel loader, the system alerts the operator at a greater distance than for static objects such as walls or columns. This intelligent classification reduces the number of unnecessary warning signals to make the machine operator’s work easier.
Brake assistant and incident map as important functions of active personnel detection
In addition to the targeted warning signals, the brake assistant and the incident map are further functions of the active personnel detection system that help to prevent accidents. As soon as the sensors detect a potential danger, the brake assistant automatically slows down the wheel loader. This eliminates the human reaction time required for conventional braking. This shortens the stopping distance by potentially crucial metres, further reducing the frequency and severity of accidents.
With each warning signal, the assistance system transmits a GPS signal to Liebherr’s LiDAT data transmission and positioning system. Based on this, Liebherr provides the incident map, a visualisation of risk zones and potential accident sources on the plant site, for every operator of a wheel loader with active personnel detection in LiDAT. This allows the plant operator to take action to prevent accidents and thus increase safety.
Liebherr participates with various technical presentations at the VDBUM grand seminar
In addition, Liebherr presented three interesting technical lectures as part of the 50th VDBUM grand seminar. “Strong partnership between the building contractor and the manufacturer”, was the title of one of them, a joint presentation by Rudolf Arnold (Liebherr-Hydraulikbagger GmbH), Thorsten Hesselbein (Liebherr-Werk Biberach GmbH) and Martin Philipp (STRABAG BMTI GmbH & Co. KG). The speakers gave an insight into the decades of successful cooperation between STRABAG, a leading European technology partner for construction services, and Liebherr based on projects they have implemented together, as well as an outlook on how foundations for the future are built together with customers. The public was also able to learn about current topics of the Liebherr Group at the Liebherr stand.
The German Association of Construction, Environmental and Mechanical Engineering (VDBUM) is a professional interest group that represents its members in all matters of everyday work and provides a forum for construction professionals. The membership includes both users and manufacturers of construction machinery with their sales and service partners. In 2013, the VDBUM launched its award to drive innovation and technical progress in the construction industry.
