Features

High construction efficiency, powerful shutting force and good perpendicularity for the diaphragm wall construction.

The diaphragm wall grab may also be installed with to maintain and repair the wall anytime during working.
The advanced electronic surveying system can accurately demonstrate the depth and the position direction of the grab on the screen, as accurate as to 0.01 degree.
Diaphragm Wall Grab
Diaphragm wall grab which is rope suspended and operated hydraulically. The 80~120 ton closing force and 8~9 second shovel opening/closing time are activated by a cylinder which is installed inside of base body. High closing forces in combination with the possibility of multiple grabbing at the trench bottom result in high excavation rates even in dense and very hard soil strata.
