About 18 Inch Inboard Pump Dredger 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 Inboard Pump 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 Inboard Pump 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.
2. About Leader Dredger Inboard Pump Dredger:
1. The dredging pump is driven by the main diesel engine through a
reduction gear box
2. The alternator, driven by an auxiliary diesel engine, provides
power and lighting for the entire dredger. The generator set
supplies power for lighting and emergency situations when not
working
3. The hydraulic oil pump is driven by an auxiliary diesel engine
4. Variable speed winches, winches and hoisting winches are driven
by hydraulic motors
5. The cutting head is driven by a hydraulic motor; the bearing of
the cutting machine has a lubricating and sealing device
6. The dredger is moved by rotating the pendulum alternately and
lifted by hydraulic cylinders
