500kN Diaphragm Wall Machine

Generally there are two types of diaphragm wall grab, which are mechanical diaphragm wall grab and hydraulic diaphragm wall grab.

Our diaphragm wall equipment are a kind of hydraulic diaphragm wall grab.

Diaphragm walls are underground structural elements principally used for retention systems and permanent foundation walls. It is one of the most efficient and versatile construction machines on the market.Our TG series hydraulic diaphragm wall grabs are ideal for pit strutting, dam anti-seepage, excavation support, dock cofferdam and foundation element, and are also suitable for the construction of square piles.

The rectangular or semicircular jaw plate of diaphragm wall and its guide device are interchangeable in the actual grab body. Unloading is done by taking advantage of the grab body's weight. When released by the rope, the grab descends with considerable force, thus helping unload materials from the jaws.As a result of their undoubted strength, simplicity and low running cost, our TG series cable-operated grabs for diaphragm walls are widely used in the construction of foundations and trenches.
