u The whole dredger is dismountable in road transportable sections.

u The engines and dredge pump are located in the center pontoon, the 2 side pontoons serve as fuel bunkers, ballast tanks and store.

u Engine room and pump section are accessible by watertight hatches

u Cutter shaft runs on roller type bearings in an enclosed shaft housing flooded with lubrication oil a lock oil tank to ensure a positive pressure inside the bearing housing is located on top of the wheelhouse.

u The spacious control cabin is ergonomically designed fitted on a raised platform with all around non obstructed view ,2 operators consoles containing engine instrumentation and controls for winches, dredge pump, suction and discharge pressure gauges, navigation light controls, airconditioned and well insulated .

u Below the control cabin is a changing room located with table, chairs and washbasin

Q:What is the difference between a cutter suction dredger and a trailing suction dredger?
TSHD is installed through the chain of dredge bucket will be dug out of the bottom mud, stored on a ship or barge dredger edges.
Q:Who has the construction plan of dredger dredger after dredger dredging and dredging with dredger barge?
Is it a filling scheme for dredger? How about a suction dredger on the side of Qingzhou? Customer feedback is also OK, you can come and have a lookSpecific contact, see user name, basic data
Q:The famous type of cutter suction dredger
The leading dredging expert, Jan De Nul, will further expand its fleet of ships, which will build a self propelled suction dredger, named JDN8069, at the Croatia shipyard UljanikBrodogradiliste. After completion, the ship will become the world's largest suction suction dredger, compared with Luxemburg, JDN dredging group currently has the world's largest suction suction dredger, "J.F.J. DeNul", power 50%. JDN8069 ship is expected to be delivered in early 2017, global operations.
Q:What is the working principle of a cutter suction dredger?
Construction principle of cutter suction dredger:The dredger is in place, the steel pile excavation construction method, horizontal positioning dredging and filling, it is with a fall in the channel center line of the main hull positioning pile as the center of the rotation, the role of the reamer for traversing on lateral swing in the channel width, the construction method of excavation section of soil layer cutting cutter.
Q:Who knows what's the name of the biggest dredger in China?
Guangzhou Waterway Bureau has the largest grab ship, the maximum bucket capacity of 50, but the efficiency is not as good as the Shanghai Waterway Bureau fighting capacity of Xinhai 27 party round clam.Most of the ships I've seen before, as well as a dredge called a chain bucket dredger, are now out of date.
Q:Classification of trailing suction dredgers for trailing suction dredger
Suction dredger is flexible, high efficiency, strong wind waves, suitable for coastal ports, the wide river and ship anchorage operation in large waves and without the cover of coastal and estuarine areas, should choose the self-propelled trailing suction dredger. Soil works suitable for loosening and less than clay hardness.
Q:How much dredging can the 4000 side /h suction dredge dredge in one day? Soft silt
The "4000 party" per hour he refers to is under design conditions. If you are digging soft mud, the hourly rate is higher than 4000, and I now ship according to Holland IHC, originally designed to be 3500 parties, we call the 4500 party. In fact, if the excavation of soft silt, pipelines in 5 kilometers or so, we can produce more than one hundred thousand per day. The instantaneous yield can reach 7000 square hours per hour. I wonder what the power of your so-called 4000 party pump is
Q:The working principle of a trailing suction dredger
Suction ships to show all sizes of the mud tank capacity, general cargo capacity is 500 ~ 1000m3. minimum drag suction dredger construction at a depth of about 3 conditions. The maximum drag suction dredger digging depth can reach 3 to 35. The suction ship belongs to the ships in waves, considerable sea dredging sailing, and mud.
Q:Does dredging dredger need relevant qualification?
I can do it for you or not! No, oh, no!
Q:3800m3 cutter suction dredger
3800m3 bucket wheel dredger is at the end of the last century according to the Ministry of transportation "based on domestic design and construction, the introduction of equipment key technology policy, the Yangtze River Waterway Bureau presided over the development of construction, Shanghai 708 Institute of design, Wuchang shipyard built China's first inland new dredger. The ship's key power equipment, dredging equipment, hydraulic systems were provided by German SKL company, United States Ellicotte (Aili, Kurt) company, the United States Dennison hydraulic company. This ship has been officially delivered to the Yichang Waterway Engineering Bureau of the Yangtze River. The name of vessel is No. 1.Bucket wheel cutting device in the river near the mouth of the soil suction, and by rotating the bucket wheel by cutting soil and water into high concentration mud, directly transported to the suction suction head of the top tube, rely on the suction centrifugal pump, the suction pipe has certain vacuum. The mud suction head, suction tube at the top end of the suction pipe, through the mud pump pressure after the mud through the mud discharging pipe into the mud barge or transported to the mud field. Through positioning piles, positioning piles, landing gear and traversing winch, the positioning of dredger, longitudinal forward movement and lateral swing of ship are achieved, and the purpose of continuous excavation of river bed soil is achieved.
