Liebherr’s new LBX 600 is responding to the unique challenges faced on urban slurry wall construction sites.
The compact size combined with the electric, zero-emission version enables work in confined spaces and noise-sensitive areas.
The LBX 600 can be flexibly equipped and customized 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 metres. For applications with restricted height, the low head with 11 metres or ultra low head with 5.8 metres can be used.
As well, the LBX 600 has a particularly slim design. The compact basic machine can be transported in one piece as the track width can be reduced to 3 metres, thanks to a telescopic undercarriage.
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.
In combination with the HSG 5-18 hydraulic slurry wall grab, the LBX 600 offers intuitive operation, which also enables hydraulic corrections to the grab alignment and a higher verticality of the trench.
The hydraulic slurry wall grab features a modular design. With the HSG 5-18 C and HSG 5-18 L, slurry walls with thicknesses between 500 and 1,800 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 metres longer. The resulting total height of the grab at 9.5 metres, and the high weight with low centre of gravity, provides better vertical positioning and are 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 tonnes or 6.5 tonnes. Bits with lengths of 2.5 metres to 3.4 metres and maximum depths of 80 metres 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-degree rotation after each grab cycle.
The high cylinder force of 1527 kN achieves impressive performance even under extreme conditions. The fill level indicator on the grab ensures high productivity throughout the entire application. The maximum permissible grab weight is 30 tonnes.
LBX 600 unplugged
The LBX 600 is also available in the battery-powered LBX 600 unplugged version. Both versions have identical performance data. One exceptional feature of the unplugged version is zero emissions. The machine does not produce any exhaust fumes and generates minimal noise, which is ideal in noise-sensitive regions and finds favour with jobsite personnel and residents.
The battery is charged using a conventional jobsite electric supply. Operation can continue as normal while charging.
Whether attached to the electric supply or not, the performance and range of application remains unchanged.
Digital solutions
All working processes for slurry wall construction can be electronically recorded and visualized using PDE, the process data recording system .
The system is operated and displayed on the PDE touchscreen in the cab. PDE records operating data from the Litronic control system, as well as data from external sensors.
Using the MyJobsite software solution all relevant process, machine and jobsite data can be recorded, displayed, analyzed, managed and evaluated in one central location.
The collected data can be accessed via a web browser when an internet connection is active. With the recorded PDE data, a working protocol is automatically generated as proof of quality directly after completion of a work process.
The parameters of the driving protocol can be defined and assigned in advance, which is an enormous time-saver.
The LiDAT data transmission and positioning system enables the fleet management of Liebherr machines. The system supplies information about localization as well as about the operation of the machines.
This includes position, operating and utilization times, fuel consumption and service interval information.
