Hydraulic Slurry Wall Grab

HSG 5-18 EN

Characteristics Basic machine HS 8130 HD with hydraulic slurry wall grab HSG 5-18

The grab convinces with its robust design and high clos-ing force. These properties provide a decisive advantage especially for hard soil conditions.

Thanks to the synchronisation of the hoisting winches high grab weights are viable and the lifting capacity of the basic machine is optimally utilized. As a standard the free-fall winches are also synchronised and can be con-trolled using a pedal.

The modular design of the grab promises a high level of flexibility and enables the optimum adaptation to jobsite requirements.

The hydraulic slurry wall grab package is based on the proven HS series. It unites precision, power and econo-my. At the same time the multifunctionality of the carrier machine is maintained 100 %.

* Admissible boom lengths for HSG 5-18

Lifting a load which exceeds the line pull of one winch is only allowed if it can be ensured that each individual winch is not overloaded. When working with a mechanical 2-rope grab the total load to be lifted is limited by the line pull of one winch. Rigging and ropes are part of the load. Max. capacities in metric tonnes do not exceed 75 % of tipping load.

Capacities in slurry wall operation are for reference only and are not pro-grammed in the LML system. All loads and counterweight configurations are max. values and must not be exceeded. Weight of additional equipment on boom (e.g. walkways, semi-Kelly guide, hose drums etc.) must be de-ducted to obtain the net capacity.

The weight of the lifting device (full grab, hoist ropes, shackle, etc.) must be deducted to obtain a net lifting value.

The grab extension increases weight and length of the grab and therefore enhances the verticality of the trench. It is recommended for depths exceeding 40 m.

Grab closing mechanism

Opening and closing of the grab is actuated by two direct-acting cylinders. These are installed with the piston rods at the top, which means they are protected inside the grab body. The robust cylinder barrels are positioned downwards.

Synchronised opening or closing of the grab jaws is mechanically ensured via push rods. This mechanism is reliable and easy to maintain.

Semi-Kelly guide (option)

With semi-Kelly guide (optional)

The optional semi-Kelly guide provides for steady guidance of the grab outside the trench. This makes rotation and alignment of the grab easier for the operator and accelerates the process.

Without semi-Kelly guide Operating the grab without the optional semi-Kelly guide increases the basic machine’s flexibility. Quick conversion for operation with mechanical grab, as a lifting crane, or for chisel application is possible. Another advantage compared to the semi-Kelly version is the lower weight on the boom.

Hydraulic rotating device with radio remote control

The rotating device allows for rotation and alignment of the grab after each grab cycle. In combination with the semi-Kelly guide the rotating movement can be even better controlled and the assistance of an employee on the ground is no longer required.

Advantages of the rotating device: • Alignment of the grab in slurry wall direction, rotation range +90° to -90° • Storing of the grab position • Rotation from 0° to 180° after each grab cycle • Radio remote control • No electric cable to the basic machine

Hydraulically adjustable guide bars (option)

Lower guide bar extensions (option)

During excavation work the grab direction can be corrected using the guide bars and so higher verticality of the slurry wall is achieved. The system is driven hydraulically and remote-controlled from the cabin. The grab must be equipped with a hydraulic rotating device.

Additionally available guide bar extensions allow for the grab to be aligned in the trench more quickly. These extensions are mounted on the existing guide bars.

Stop-end guide (option)

The slurry wall grab is guided vertically along the stop-end element via the stop-end guide. Furthermore, this guide serves to scrape off and loosen the excess/seeping concrete from the stop-end element.

Additional weight (option)

Additional weights are available in various sizes up to 7 t.

The Liebherr Verticality Assistant for hydraulic and mechanical slurry wall grabs is fully integrated in the Liebherr machine’s control system for monitoring and recording the slurry wall installation process. With the help of the Verticality Assistant the deviations between the slurry wall and the grab along the X and Y axes, as well as the rotation round the Z axis are measured. Additionally the productivity data is recorded for the complete slurry wall process. The measurement is carried out using a sensor, which is positioned on the grab.

An innovative graphically displayed host system guides through the various stages of the measurement operation. The success of the measurement is ensured through the automatic reduction in the lowering speed. Data is transferred from the grab to the machine via Bluetooth technology (cable transfer is optional).

The data is clearly displayed on the PDE® monitor in the operator’s cabin. On the one hand, the measured values serve as a guideline for completing the trench, and on the other hand, the recordings of the measurement operation can be exported for evaluation to the process data reporting system PDR2, where they can be extensively analysed.

LiDAT® enables the mobile communication of measured data from the machine to the reporting software PDR2. The reports generated in PDR2 enable the traceability of the trench and can also be used as proof of quality.

The Verticality Assistant is fully incorporated in the existing mod-ularly structured concept of digital solutions from Liebherr.
