What is the maximum excavation depth and soil hardness?

The grab ensures verticality and prevents deviation at extreme depths of 30m+. It is suitable for excavating diaphragm walls in all soil conditions up to a hardness of 70 MPa.

Is it possible to increase the grab's weight for harder soil conditions?

Yes, the grab is available with extra ballast to reach a total weight of up to 35 tons for even the most demanding projects.

Product Q&A

Q:What is the operating principle of this mechanical diaphragm wall grab?

It relies on deadweight gravitational impact and mechanical wire-rope reeving rather than onboard hydraulics, using a two-line mechanical rope system for holding and closing.

Q:What crane capacity is required for operation?

A friction-clutch crawler crane or dedicated duty-cycle crane rated for at least 35 to 50 tons is typically required to handle the dead weight and dynamic payload.

Q:Can the jaw width be customized for different wall thicknesses?

Yes, the grab features modular jaw sets. The main body can be fitted with 400 mm, 500 mm, or 600 mm jaws depending on project structural wall thickness requirements.

Q:What materials are used for the cutting edges and jaws?

The cutting edges are made of steel 450 (NM450) and are especially hardened for high abrasion resistance. Jaws can be angular, round, rectangular, or round shaped.

Q:How are maintenance and wear parts handled?

All grab teeth, wire rope pulleys, and jaws are quickly exchangeable as ready-to-use components. Pulleys have maintenance-free bearings filled with grease or oil.
