About 26 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 26 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 26 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.
