About 18 Inch Lake Suction Dredger 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 Lake Suction Dredger 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.
About 18 Inch Lake Suction Dredger 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.

4. Lake Suction Dredger 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.
