Dredge Cutter Features

We Offer Best Features

  • HIGH TORQUE

    Electric torque/ring motors are used. High number of poles. Permanent magnets rotor. Different speed and torque is possible. Low maintenance required.

  • HIGH EFFICIENCY

    The cutter head is using direct electric ring motors mounted on the cutter special hollow shaft. The design eliminates the use of long shafts, intermediate bearing blocks, gearboxes, and couplings. Due to the direct drive, the efficiency is higher than the long shaft system and higher than the hydraulic drive.

  • EASY INSTALLATION AND MAINTENANCE

    Fewer parts to assemble. Composite bearings. No friction in the motor. Cutter hub threaded assembly. No oils and seals

REDUCTION OF SPILLAGE

Significantly less spillage is achieved during the dredging process in both over-cut and under-cut due to the unique cutter head design with the principles:

  • The Cutter blades are based on Archimedes screw pump and aerofoil design which creates axial pumping and prevents the cut material from falling.
  • Material flow toward the suction pipe
  • Due to Archimedes design no centrifugal forces in the cutter head
  • The cutter head and suction pipe are aligned
  • The aerofoil shape of the blades leads the material to the suction pipe

Steps Forward

Navigating With Cutter

More Production

Low Turbidity

Accurate Cut

High Moment of Inertia

A unique feature of the electric drive cutter head is the high moment of inertia. Utilizing the center axis of rotation as a suction system, most of the weights are placed far from the axis of rotation. With this, the arrangement is much simpler and eliminates the use of expensive long shaft arrangements.

Improves Dredge Pump Performance

Since the Drill Cutter is utilizing the center axis of rotation as a suction system, it eliminates the use of suction mouth which results in a much more fluent suction piping arrangement.
