OEM diaphragm wall grab equipment

Diaphragm wall construction is widely used in civil engineering projects such as deep excavations, retaining structures, and foundation systems. These operations typically involve grab machines (Schlitzwandgreifer), operating under high static loads combined with frequent load cycles.

Our Tiefbau Wedge Socket is incorporated in diaphragm wall grab equipment manufactured by OEM Sennebogen. The socket provides a secure termination of the hoisting rope to the grab and ensures reliable load transfer during operation. The design is specifically tailored to this application, with particular attention to fatigue behaviour and long-term performance under repeated loading.
