A new piling and drilling rig from Liebherr, the LRB 355, was recently put to work close to its manufacturing site in Austria. The rig was used by an Austrian construction company, Hilti & Jehle GmbH, to carry out sheet piling work in Frastanz.
Rondo Ganahl AG, a company that specializes in the production of paper and packaging, is building a new high bay warehouse and extension for logistics, as well as carrying out modifications to existing facilities. Parts of the deep foundation work were subcontracted to Hilti & Jehle GmbH by the joint venture I + R Schertler / Tomaselli.
Sheet piling work had to be carried out on an area of 7,500 square meters in order to lower the groundwater level by approximately 3 meters and to secure the foundation pit. The LRB 355 piling and drilling rig installed U profile sheet piles with lengths of 11-12 meters in the ground.
The LRB has a robust undercarriage as well as long crawlers that are designed ensure a high level of stability. Parallel kinematics give the rig a large working radius. The assembly of all winches directly on the leader is another feature included in the design of the LRb 355. On the one hand, this enables a clear view of the main winch from the operator’s cab and, on the other hand, ensures that the ropes do not move when the leader is adjusted.
In addition to sheet pile installation using a vibrator, the LRB 355 is suitable for other common drilling methods including drilling with Kelly equipment, full displacement tool or continuous flight auger as well as for soil mixing and operation with hydraulic hammer.
“With the LRB 355 from Liebherr we have a modern, top-line machine at our disposal. Thanks to its multi-functionality the quality of foundation work is improved and, at the same time, we are more flexible and can work more efficiently,” says Markus Maehr from Hilti & Jehle.
Liebherr’s product range includes earthmoving and material handling machinery, mining equipment, mobile cranes, construction cranes, machine tools and automation systems as well as high-performance components for mechanical, hydraulic and electrical drive and control technology.
