The Watermaster amphibious dredger is a multi purpose floating machine designed for sediment removal in water bodies with limited access. Unlike conventional dredgers that require deep water or launch ramps, the Watermaster amphibious dredger operates in shallow waters, swamps, canals, and ponds with water depths as low as 0.5 meters. This machine combines an excavator arm, a cutter pump system, and a pontoon based undercarriage that moves on tracks in swampy terrain.
The Watermaster amphibious dredger uses a hydraulic cutter head to loosen compacted sediments. The cutter head diameter ranges from 600 mm to 900 mm depending on the model. The slurry is then pumped through a discharge pipe with diameters of 200 mm to 300 mm. Maximum pumping distance for the Watermaster amphibious dredger reaches 1500 meters horizontally with a 10 meter lift. Production rates vary from 80 cubic meters per hour for sandy silt to 200 cubic meters per hour for loose organic material.
The amphibious design allows the Watermaster amphibious dredger to walk on soft ground using steel track pads with ground pressure below 0.3 kg per square centimeter. This feature enables operation in marshlands where wheeled or conventional floating equipment cannot go. The machine can transition from land to water without assistance. In water, the pontoons provide buoyancy with a draft of only 0.8 meters when fully equipped.
ITECH Co.,Ltd. supplies the Watermaster amphibious dredger to clients in lake restoration, port maintenance, and mining tailings management. Typical applications include removing silt from irrigation canals with widths of 4 to 10 meters. The machine rotates 360 degrees on its turntable, allowing it to work around obstacles like bridge piers and submerged pipes. The cutter pump operates at speeds of 600 to 1000 rpm, generating a slurry density of 20 to 30 percent solids by weight.
Operational data from projects show that a Watermaster amphibious dredger removes 1200 cubic meters of sediment in an 8 hour shift when working in non cohesive materials. For cohesive clay, production drops to 70 cubic meters per hour due to higher cutter torque requirements. Fuel consumption averages 25 liters per hour for the main engine at 1800 rpm. The hydraulic system pressure is set at 300 bar.
Maintenance intervals for the Watermaster amphibious dredger are based on engine hours. The cutter head teeth require replacement every 150 to 200 hours when working in abrasive sand. The pump casing wear life is 800 hours in silty conditions. The amphibious tracks use sealed bearings that require greasing every 50 hours. ITECH Co.,Ltd. provides a maintenance schedule that includes daily checks of hydraulic oil levels and weekly inspections of the suction screen.
Transporting the Watermaster amphibious dredger between sites requires a low bed trailer due to its width of 3.1 meters and length of 8.5 meters when the boom is folded. Operating weight ranges from 16 to 24 metric tons depending on the model. The machine meets European emission standards Stage V for diesel engines. Noise levels at the operator station are 78 decibels.
The Watermaster amphibious dredger includes a telescopic boom with a reach of 7 meters from the turntable center. This reach allows cleaning of bank slopes without repositioning the machine. The boom angle ranges from minus 30 degrees to plus 45 degrees. A depth indicator shows the cutter head position relative to water level. The operator cabin has heating and air conditioning for year round operation.
For projects requiring long distance slurry transport, the Watermaster amphibious dredger can be equipped with a booster pump station. The booster pump increases discharge pressure by 4 bar, extending pumping range to 2500 meters. ITECH Co.,Ltd. offers this as an optional package. The machine also supports remote monitoring of pump pressure, engine load, and hydraulic oil temperature through a telemetry system.
In summary, the Watermaster amphibious dredger provides a practical solution for sediment removal in shallow or swampy environments. Its combination of tracked mobility and floating capability allows access to sites that other dredgers cannot enter. With documented production rates and maintenance requirements, this machine suits contractors and government agencies managing waterway siltation.
