Wetland Digging Arm

12 m Amphibious Boom for Pontoon Mounted Excavators

When the ground cannot carry a machine, the arm goes on water. This 12 m boom is built for our amphibious pontoon sets: 11.6 m of reach, 8.5 m of depth and a 0.5 m³ bucket, with the boom foot reinforced where it meets the pontoon turret.

We build the boom and the pontoon in the same workshop, so the mounting pattern, buoyancy calculation and hose routing are matched before either part leaves the factory.

Talk to our factory engineer on WhatsApp: +86 180 2625 4557 — send your machine model, stick length and working depth, and we return a drawing and quotation within one working day.
