Extremely strong, especially in the heavy-duty range
Liebherr-Hydraulikbagger GmbH has expanded its production area at its founding site in Kirchdorf an der Iller (Baden-Württemberg) to more than 23,000 square metres. For effective drainage of the extensive site, where many heavy-duty vehicles travel, the HYDROblock® heavy-duty drainage channel system, specially developed for these high requirements, was installed.
Involved in trend-setting projects
The small construction company developed into a globally successful manufacturer of construction machinery and many other technically sophisticated products and is involved in countless trend-setting major projects with its machines. These include the Elbe Philharmonic Hall in Hamburg, the Lakhta Tower in St. Petersburg and trams in the US metropolis of San Francisco.
The company produces about 2,500 machines a year and develops and manufactures an extensive range of high-quality hydraulic excavators, material handlers and articulated dump trucks in Kirchdorf. The company is the world market leader in the mobile excavator segment. In the newly built logistics centre of Liebherr Hydraulikbagger GmbH, among other things, a new goods receiving area with high-bay warehouses including a truck lock with a 20t crane system has been created.
Effective drainage on the heavy-duty site
Drainage channels of the HYDROblock® type, here in the DN 200 version with an inlet cross-section of 780 cm²/m, already offer significant advantages in terms of logistics on the construction site and during transport.
The channel elements with an overall length of 1,000 mm, a height of 295 mm and a component weight of 66.1 kg can be installed quickly and easily. The installation of this linear drainage system is also advantageous with regard to the monolithic construction, which ensures rattle-free operation by dispensing with loose parts.
Due to the material EN-GJS-500 (ductile cast iron), the channel system also has significant advantages over other materials in terms of material fatigue, especially in the heavy load range. The monolithic channel bodies are predestined for high loads, even with transverse overtravel. The robust system can be used up to load class F 900 according to DIN EN 1433. Matching inspection elements allow for easy maintenance and cleaning.
Another advantage of the elements is their easy installation. Thanks to the push-fit socket system, the drainage channel can be connected like a pipe by spigot end and socket. This allows full compatibility with commercially available KG pipes. The integrated NBR socket seal at the channel joint ensures the tightness of the channel system even in the event of possible settlements. Thanks to the sophisticated design, the HYDROblock® drainage channel can be paved, concreted or asphalted directly, regardless of the load class.
