The Watermaster amphibious multipurpose dredger is designed to perform seven distinct tasks using interchangeable attachments. Beyond standard dredging, this machine can cut vegetation, install pilings, clean trash racks, pump sludge, excavate trenches, and spread granular materials. The quick coupler system allows attachment changes in 15 minutes by one person. ITECH Co.,Ltd. supplies the Watermaster amphibious multipurpose dredger with all seven attachments for customers requiring flexibility.
The primary function of the Watermaster amphibious multipurpose dredger is sediment removal using the cutter pump attachment. The pump produces 200 cubic meters per hour of slurry at 20 percent density. The cutter head loosens material within a 3 meter wide swath. Operators can switch to the vegetation cutting attachment which uses dual reciprocating blades with 40 mm tooth spacing. The vegetation cutter clears reeds and water hyacinths at rates of 1.5 hectares per day.
The Watermaster amphibious multipurpose dredger with the piling hammer attachment installs wooden or steel piles up to 8 meters long. The hammer delivers 800 joules per blow at 500 blows per minute. A guide frame holds the pile vertical within 2 degrees. This attachment is used for bank protection and mooring installation. The machine holds the pile while advancing the hammer using the boom hydraulics. Piling rate is 20 piles per shift for 4 meter long sections.
The trash rack cleaning attachment for the Watermaster amphibious multipurpose dredger consists of a rotating rake with 50 mm tines. The rake reaches 4 meters below water surface to remove debris from intake structures. The tines rotate at 20 rpm and deposit debris into a hopper on the machine deck. Hydroelectric plants use this attachment to maintain cooling water intakes. One plant reported 30 percent reduced downtime after adopting this attachment.
The sludge pumping attachment turns the Watermaster amphibious multipurpose dredger into a transfer unit. This attachment uses a submersible pump with 150 mm discharge instead of the cutter head. The pump moves sludge from lagoons to dewatering bags or centrifuges. Maximum solids concentration for pumping is 15 percent by weight. Pumping distance reaches 200 meters without a booster. Flow rate is 80 cubic meters per hour for sludge with 90 percent water content.
The trenching attachment on the Watermaster amphibious multipurpose dredger cuts trenches in soft ground for cable or pipe installation. The trenching wheel has 300 mm width and cuts to 1.5 meters depth. A screw conveyor removes spoils from the trench. The machine walks along the trench line using GPS guidance for straight alignment. Trenching speed is 50 meters per hour in silty soil and 30 meters per hour in clay. This attachment is used for submarine cable projects in intertidal zones.
The granular material spreading attachment allows the Watermaster amphibious multipurpose dredger to place sand or gravel on banks or beaches. A belt conveyor with variable speed throws material 8 meters from the machine center. Spreading rate is 40 cubic meters per hour for coarse sand. The attachment includes a leveling blade for final grading. Beach nourishment projects use this attachment to distribute dredged sand evenly. One project in the Netherlands spread 12,000 cubic meters over 600 meters of shoreline.
Changeover between attachments on the Watermaster amphibious multipurpose dredger follows a standard procedure. The operator lowers the boom to a service stand. Two hydraulic hoses are disconnected using a pressure release valve. Four pins are removed from the attachment pivot. The quick coupler engages the new attachment after alignment using the boom controls. ITECH Co.,Ltd. provides a color coded chart showing hydraulic port connections for each attachment.
The Watermaster amphibious multipurpose dredger uses the same undercarriage and power unit for all attachments. Engine power is 250 kW for the Pro model which is recommended for multipurpose use. The Classic model with 210 kW can use the dredging and vegetation attachments but not the piling hammer due to hydraulic flow requirements. The Heavy model with 300 kW supports all attachments plus a rock ripper for hard material.
Training for the Watermaster amphibious multipurpose dredger includes 2 days on attachment changeover procedures. Operators learn to identify correct hydraulic pressure settings for each attachment. Vegetation cutting requires 150 bar pressure. Piling hammer requires 250 bar. Sludge pumping requires 120 bar. Using incorrect pressure reduces attachment life or causes failure. ITECH Co.,Ltd. includes a pressure setting guide on a placard inside the operator cabin.
Case studies of the Watermaster amphibious multipurpose dredger from three continents show return on investment within 18 months for contractors owning this machine. A contractor in Florida used the machine for canal dredging for 6 months, then vegetation clearing for 2 months, then piling for a dock project for 3 months. Total utilization was 85 percent versus 50 percent for a single purpose dredger. The contractor reported 40 percent higher annual revenue compared to previous single purpose equipment.
ITECH Co.,Ltd. sells the Watermaster amphibious multipurpose dredger as a complete package with all seven attachments for 520,000 USD for the Pro model. The package includes a shipping container with organized storage for each attachment. Individual attachments are also sold separately starting at 8,000 USD for the vegetation cutter to 28,000 USD for the piling hammer. Buyers who purchase the complete package receive a 10 percent discount on spare parts for 2 years.
In summary, the Watermaster amphibious multipurpose dredger transforms from a sediment removal machine into five other specialized tools. This versatility allows one machine to serve multiple project phases or seasonal tasks. Contractors who face varying job requirements benefit from the reduced capital cost of one machine versus several. ITECH Co.,Ltd. provides all attachments with full warranty and technical support.
