Liebherr Targets Urban Sites With New Carrier Machine For Slurry Wall Construction
Liebherr has launched a new carrier machine for slurry wall construction, the LBX 600, aimed at meeting the requirements of jobsites in urban areas.
The electrically driven machine can be fitted with mechanical or hydraulic grabs and features a modular system with three different booms: the standard version of the machine has a total height of 17.8m. For applications with restricted height, such as working under bridges, the Low Head with 11 m or Ultra Low Head with 5.8 m can be used.
The machine also has a telescopic undercarriage that allows track width to be reduced to 3m.
The carrier machine is not only designed for work using a hydraulic grab but also with a mechanical grab or chisel, thanks to the two free-fall winches with a line pull of 300 kN each.
The hydraulic slurry wall grab is modularly designed and as the names of the grabs imply, HSG 5-18 C and HSG 5-18 L, slurry walls with thicknesses between 500mm and 1800mm 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.
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 4.4t or 6.5t. 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.
The maximum permissible grab weight is 30 tonnes.
The LBX 600 is available in both conventional and battery-powered versions, the LBX 600 unplugged. Both versions have identical performance data.
The unplugged version can be charged using a conventional jobsite electric supply. Operation can continue as normal while charging.
Liebherr offers the LBX 600 and the LBX 600 unplugged as a complete package with hydraulic slurry wall grab HSG 5-18.
