About 18 Inch Dredger Ship Cutter Head
For one cutter head, there are 5 blade,6 or 7 teeth equipped on one blade. There is material Cr. for easy-wearing proof. Cutter head is driven by hydraulic motor; cutter bearing has lubrication seal-in units.
The cutter motor is hydraulic driven low speed and high torque heavy duty design. The cutter motor is mounted on the cutter front piece on the ladder end. A special cover is provided to protect the motor from damage due to sand, rocks and debris. The cover can be removed from easy inspection and maintenance.
About 18 Inch Dredger Ship Dredge Pump
The dredge pump is high efficiency made from wear resistant casting impeller and liners fitted on heavy duty shaft and high quality roller bearings.
The impeller is fitted on the shaft by trapezoid thread directly machine on the shaft end. The shaft sealing is a water cooled sealing that can be replaced after wear life. The impeller is a special type of double curved vanes high efficiency and wear life optimized tested in laboratory and onboard of dredgers. The impeller is fixed on the shaft
by trapezoid thread machined directly in the impeller hub.
The pump casing has a shape of a volute designed of a high efficiency and wear life optimized tested in laboratory and onboard of dredgers. The pump liners are made of high wear resistant materials and thick wall thickness to maximize the wear life. The casting covers are made from fabricated steel stiffened where necessary and
machining to fit the case and the liners.
About 18 Inch Dredger Ship Ladder
The ladder and cutter head for cutter suction dredger are mainly made of ladder steel structure, suction pipe, left and right traversing pulley, ladder lift and down pulley block, hydraulic pipe, cutter head, cutter head driving hydraulic motor, gear box etc.. The ladder is fixed on the main pontoon by two axle pins. Its main function is to install
suction pipe and make the cutter head descend to certain depth and cut sand.
2 . About 18 Inch Dredger Ship Application
1. The sand dredger for sale is used for cleaning river silt, sand production and mining projuct.
2. Suitable for heavy duty opetations in tripical climates and in sheltered waters.
3. Applied to dredging rivers, lakes and ponds, reclaiming land, cleaning ports and pumping sand.
4. Mainly service for the master dredger and transporter for delivering sand to land.
3. Dredger Ship Production Process
Material cutting.
The thickness of the steel plate is 6 mm, which is very strong and strong enough for this type of winch dredger. We carefully cut the material of the dredger with an automatic plasma cutter.
welding.
All our workers are senior welders with welding skills to ensure that the welding is beautiful and there is no gap.
painting.
After the dredger pontoon is completed, we will paint the small winch dredger with anti-rust paint and topcoat. The paint color of the dredger can be specified according to customer requirements.
The winch dredger is assembled for sale.
We assemble and connect sand pumps, water pumps, pump engines, winches, hand frames, sand suction rubber hoses and fuel tanks.
The dredger undergoes sales testing before delivery. We started the engine and checked the working condition of the pump and winch. After ensuring that all the dredgers for sale were in the design state, we delivered the dredgers for sale.
