Cable-operated grabs for diaphragm Walls are versatile pieces of equipment widely used in the construction of foundations and trenches because of their undoubted strength, simplicity and low running cost, especially on hard ground. Rectangular or semi-circular jaws with their relative guides are interchangeable on the actual grab body. Unloading is done by taking advantage of the grab body's weight, which when released by the rope, descends with considerable force, thus helps detaching material from the jaws.
