Grab Systems

Due to its robust design and its numerous extensions and equipment options, the DHG/V hydraulic diaphragm wall grab covers a wide range of applications. Equipped with a hydraulically or mechanically operated hose reel system, it can either be deployed with an MC duty-cycle crane or a special GB grab carrier. With the help of an assistant system, deviations can be detected and corrected by the rig operator.

 

The trench cutters and grabs can be mounted on different carrier systems. A wide range of base carriers allows an optimum configuration of the complete system to be achieved in line with the requirements and site-specific conditions. An MC base carrier can also be used for other specialist foundation engineering works or as lifting equipment, whilst a BG base carrier can also easily be converted into a hydraulic pile drilling rig.
