2. About Leader Dredger Dredge Machine Features:
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.
