amphibious excavator pontoon undercarriage

Product Description

This pontoon undercarriage is built around the CAT 320D 20 ton class machine and is used where the ground will not carry a standard tracked excavator. The two floats spread the machine weight over a wide waterline area, so the excavator keeps digging in swamp, peat and soft silt instead of sinking to the track frames.

The floats are fabricated from Q355B manganese steel plate with internal bulkheads. Sealed chain boxes keep water and mud away from the chain, and the chain plates are a high strength wear resistant grade so the undercarriage still drives when the bottom is abrasive sand.

On Site Performance

On swamp dredging work the pontoon keeps a stable working platform while the boom reaches out for silt and vegetation. The wide floats limit roll when the bucket swings to the side, and the low draft lets the machine work in shallow marsh channels that a barge cannot enter.

Factory Production

Pontoons are cut, formed, welded and tested in our own workshop. Every float is checked for weld penetration and water tightness before painting, and the completed undercarriage is assembled with the chain and driven under power before it is loaded.
