Liebherr launches a new carrier machine for slurry wall construction on the market. The LBX 600’s compact size, in particular, fulfils the requirements of jobsites in urban areas. The electrically driven unplugged version also impresses with its zero-emission advantages. The LBX 600 can be fitted with mechanical or hydraulic grabs. The modular boom system allows for three different versions of the machine and a high degree of flexibility.
With the LBX 600, the new carrier machine for slurry wall construction, Liebherr-Werk Nenzing GmbH is responding to the unique challenges faced on urban jobsites. The compact size combined with the unplugged version enables work in even the most confined and noise-sensitive areas. The LBX 600 can be flexibly equipped and customised to meet site requirements thanks to a modular system with three different booms. The standard version of the machine has a total height of 17.8 m. For applications with restricted height, e.g. working under bridges, the Low Head with 11 m or Ultra Low Head with 5.8 m can be used. The LBX 600 has an awe-inspiring slim design. The compact basic machine can be transported in one piece as, thanks to the telescopic undercarriage, the track width can be reduced to 3 m.
Powerful grip
The carrier machine is designed for work using a hydraulic grab and a mechanical grab or chisel, thanks to the two free-fall winches with a line pull of 300 kN each. In combination with the HSG 5-18 hydraulic slurry wall grab, the LBX 600 offers very intuitive operation. This also enables hydraulic corrections to the grab alignment and thus a higher verticality of the trench.
The hydraulic slurry wall grab is modularly designed and has a highly robust base body. As the names of the grabs imply, HSG 5-18 C and HSG 5-18 L, slurry walls with thicknesses between 500 and 1800 mm can be installed, depending on the composition. The term “C” (compact) stands for the compact standard design for the Low Head Version of the LBX 600, while the base body of the “L” (large) version is 2.5 m longer. The resulting total height of the grab at 9.5 m and the high weight with low centre of gravity provide for even better vertical positioning and are especially advantageous when installing larger dimensioned slurry walls.
When working in difficult ground conditions, the execution of the work can be improved through increasing the dead weight of the grab with an additional weight of 4.4 t or 6.5 t. Bites with lengths of 2500-3400 mm and maximum depths of 80 m can be excavated with the grab.
The slurry wall grab is fitted with a hydraulic rotating device, which allows the grab to be aligned in all directions and provides for quick and operator-friendly 180°-rotation after each grab cycle. The high cylinder force of 1527 kN attains an unbeatable performance even under extreme conditions. The fill level indicator on the grab ensures high productivity throughout the entire application. The maximum permissible grab weight – i.e. grab including filling capacity – is 30 tonnes.
