Q:What is the difference between a cutter suction dredger and a trailing suction dredger?
Extend the straw to the bottom of the water, turn on the mixer, and stir up the mud at the bottom of the water. Then suck the mud out of the pipe and send it to the site by the pipe.
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:Advantages and disadvantages of trailing suction dredger for trailing suction dredger
The drag suction dredger is often equipped with a lateral thruster in the bow, which has better handling performance. The anchor is not anchored or anchored by the cable during construction, so it has little interference to navigation
Q:The famous type of cutter suction dredger
MAN provides engines for the world's largest suction hopper dredger.
Q:What are the crew members on the dredge?
The dredge work generally is not very tired, after all, the mechanization of things, the need for artificial little ~ ~ for one is general and maintenance of turbine operation, as well as the ship fuel supply etc..
Q:Who knows what's the name of the biggest dredger in China?
Shanghai Waterway Bureau trailingsuction ship strength slightly, most of its name to "Xinhai" at the beginning, the Phoenix as the representative of the Xinhai tank volume is about 16000m the ship should be fand the largest and most advanced tshd. To say that the largest is the new sea lion, but the head is large, inefficient, difficult to enter the stream.
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 content of dredger dredging is generally 15 - 25%, 4000 way water flow you can count themselves, can use Baidu Search Xintuo heavy machinery, specializing in the production of dredger, dredging, pumping sand and other equipment, gold rush ship products exported to Africa and South Asia and other countries and regions
Q:Does dredging dredger need relevant qualification?
This should be based on the requirements of your local department, which is not required in general
Q:3800m3 cutter suction dredger
The 3800m3 cutter suction dredger says 3800m3 of sediment can be dug per hour!I designed the dredge pump, the ship is generally named after dredging flow, but also by the flow of water named
