Main Engine & Auxiliary Engine
CUMMINS ENGINE is our standard configuration of dredgers. As we all know, Cummins engine, which is
from America, also is famous of its long using time, lower oil consumption and small noisy. Its performance is
very high. In addition, it works more steadily and frequently. We choose Cummins for our dredger, it makes our
dredger more efficient.
Dredging 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 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.
Cutter Head
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.
Swing Hydraulic Winches
For ladder side pull two winches are provided on the front of the main pontoon mounted on a stiffened foundation.The winch is hydraulically driven through a reduction gearbox build in the winch structure.The
winch has a disc brake that is automatically activated in case of pressure drop.The winch is operated from
the control cabin and has variable speed.
