- Q:What is the difference between a cutter suction dredger and a trailing suction dredger?
- The work of a cutter suction dredger works through an agitator in the head of a straw and straw.
- Q:How much dredging can the 4000 side /h suction dredge dredge in one day? Soft silt
- The pump in the cabin and the underwater pump are full load. The length of the pipeline is within 3 kilometers, and the depth is about -16 meters. According to the rate of 18 hours per day, the production rate is 61200 according to 3400.The actual amount should be between 45000 and 55000.
- Q:3800m3 cutter suction dredger
- Should be the hour efficiency of 3800 cubic meters, 3800 cubic meters of water or flow, I feel your problems are wrong, some 3800 type dredger, Holland IHC company, but refers to the total installed power. So I think it is type 3800, not 3800M3.
- Q:Does dredging dredger need relevant qualification?
- I can do it for you or not! No, oh, no!
- 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27 party round clam.Most of the ships I've seen before, as well as a dredge called a chain bucket dredger, are now out of date.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: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:What are the crew members on the dredge?
- But in general, the dredger crew responsible for the work can be divided into: navigation, communication and work positioning on the ship, electrician, turbine, maintenance, and operation personnel (dredging) and special equipment (such as grab dredger crane and grab operation, cutter suction, suction dredger winch, water pump operation etc.).
- Q:What is the working principle of a cutter suction dredger?
- The working principle of cutter suction dredger: to locate the pile as the center, swing to dredge, forward, like walk, another piece of steel columns alternately changing piles, cutter dredging process fanned forward. The operation of the cutter suction dredger can be completed continuously, such as dredging, transporting mud and unloading mud. It is a kind of dredger with high efficiency and low cost.
- 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: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.
