During Bauma, the managing directors of Prangenberg & Zaum GmbH (P&Z) – a family-run German company specialising in demolition and restoration – were handed the keys to their first Liebherr crawler excavator, an R 998 SME. At P&Z’s request, the 100-tonne-plus machine was specially modified in several ways, in particular for optimal use with an 11-tonne shear.
The implementation of custom specifications is made possible by the Liebherr Application Center at Liebherr France SAS, which implements customers’ individual requirements. This R 998 SME is used for selective demolition work during deconstruction.
P&Z requested a variety of custom specifications for its new crawler excavator, to enable higher productivity along with more comfort and safety during demolition work. Equipment installed at the company’s request included, among other items, improved hydraulics for the shear, a dust filter to clean cab air, and a sprinkler system to prevent dust formation. In addition, the gooseneck boom and special stick allow recovery of demolition material on the ground. P&Z has already ordered, in addition, an R 972 Liebherr crawler excavator with a similar custom configuration. A key role in needs identification and project implementation was also played by Liebherr dealer WBI Bau- und Industriemaschinen GmbH, based in Dormagen (Germany).
“We were very happy with the advice from the dealer, WBI, and with the implementation of the technical details directly by Liebherr,” said Tobias Prangenberg.
The Liebherr Application Center fulfils the growing customer demand for specially modified crawler excavators. This team of specialists within Liebherr France SAS processes customer requests forwarded to them by the sales team. The Liebherr Application Center’s goal is to find the best solution for the customer’s requirements.
Custom solutions offer customers numerous benefits, for example reduced fuel consumption through optimised hydraulics, compliance with transport requirements right from the development stage, and high availability of spare parts. The design features and adaptability of the standard product ranges enable guaranteed CE marking and custom modifications in original manufacturer quality.
