A New Dredger Ship Designed In Cooperation With China'S Famous Ship Design And Research Institute
1. Why Choose Leader Dredger Hydraulic Dredger Ship?
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.
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. 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 Hydraulic winch
To support the ladder, a hoisting winch is provided at the front of the main pontoon, which is installed on a solid foundation. The winch is hydraulically driven by the reduction gear box in the winch structure. The winch has a disc brake, which is automatically activated when the pressure drops. The winch is operated from the control room
and has a fixed speed.
For the lateral pull of the ladder, there are two winches at the front of the main pontoon, which are installed on a solid foundation. The winch is hydraulically driven by the reduction gear box in the winch structure. The winch has a disc brake, which is automatically activated when the pressure drops. The winch is operated from the control
room with variable speed.
About 18 Inch Dredger Ship Hydraulic system
The hydraulic system is the most important part of the river sand dredger and bucket wheel dredger. The hydraulic system is very demanding and strict; it is the main artery of the entire sand dredger. The side traction winch of the dredger, the lifting winch and the cutting head are driven by hydraulic motors.
We use hydraulic pressure to drive the entire dredger, including winches, cutting machines, hydraulic cylinders, etc. The valve is REXROTH, and the hydraulic control system is SIEMENS PLC.
