Diaphragm Wall Grabs (mechanical)

Mechanical grabs are the best solution to excavate diaphragm walls in all soil conditions up to a soil hardness of 70 mPA as light chisseling work is possible. The SWG series of diaphragm wall grabs is available with grab extensions for a total length of 10 or 12 m and also with extra ballast to reach a total weight of up to 22550 kg for even the most demanding projects.

Jaws may be rectangular or round shape. Jaws, ropes, pulleys and different teeth can be quickly replaced on site without any problems. All rope and guide pulleys have adequately dimensioned, maintenance-free bearings filled with grease.

We also supply hydraulic diaphragm wall grabs with inclination measuring and monitoring systems to guarantee a verticality of the diaphragm wall of 1 : 800. The recorded data of the complete excavation procedure can be stored and printed out for further use.
