Product Description

1. General

Self propelled amphibious multi function dredger Watermaster, Multifunctional pontoons mounted machine. It is a combination of  a dredging machine with backhoe bucket and a suction dredger. It can do dredging, reclamation, vegetation removing, piling work in very shallow waters, wetland or even dry land, like costal, reservoir,swamp,lake, inland river, ponds,etc.  It can cruise at about 4 knots speed by using its own propulsion system and move on dry land by using its excavator arm and tilting back stabilizers.


 

2. Advantages

1) Easy for dispatch, transportable on public roads on a standard size trailer, transport as a complete unit-no need assembling times, move in and out of water independently without crane assistance.

2) Cruises on the site with it's own propulsion system,

3) Use front and rear stabilizers to anchor and balance itself, make the machine in efficient working.

4) High efficiency, combination of submersible pump and cutter make it have a high concentration even can reach 30%.

5) One person operating, operating principle is similar with excavator.

6) Can work very shallow and narrow locations-where most other machines cannot, like closed river, channel, sedimentation tank, reservoir, pond, etc.

7) Install lighting system for continuously working and improve efficiency.
