Get A QuoteOverview
SANY hydraulic grabs build deep concrete diaphragm walls for basement, cut-off and retaining structures in urban foundation works. The range pairs diaphragm wall grabs with a Kelly guided grab for efficient, smart trenching.
The SH500 and SH700 are the diaphragm wall grabs, and the SR235-S-DW Kelly guided grab extends the offering to narrower panels. Groove widths span 500–1500 mm — the SH700 reaching up to 1500 mm — with depths to 80 m and operating weight up to 130 t for reliable slurry-wall trenching in difficult ground.
Diaphragm wall work depends on trench accuracy and grab reliability. SANY supports tooling selection, operator training and wear-parts supply through its piling equipment network. Share your panel width, depth and ground conditions for a grab recommendation and quote.
