Successful cases

In June 2018, we got the inquiry from Fiji customer for river dredging. The customer just came to the dredging business, as a trial order, he wanted to use small invest to get high output of the sand dredger.

Fiji is a very beautiful place where many people go for holiday, so if the customer carries out sand dredging, he will be required to get the license in the local government . In the dredging place, in order to protect the clean water area from sand-water mixture of sand dredging site, the customer also needs the silt curtain to meet the rules of environment.

After communicated with the customer, we knew the working conditions as following:

  1. Dredge Depth: Max 5m
  2. Water depthL 3m
  3. Sand output: 50-60m³/h
  4. Sand material: Fine sand without big particle, gravel or rubbish
  5. Discharge distance: 300m

Generally speaking, dredging machines are equipped with small sand pump. But the discharge distance our customer require is 300m, it exceeds the discharge distance range of small sand pump, so we equip gravel sand pump on the dredging machines, this kind of gravel sand pump dredger not only reduces customers cost, but also meets the requirement of discharge distance.small sand dredger

The customer was worried about the balance of the dredging machines. Our engineers also considered of the possible things. So We designed the dredging machines according to the customized requests. We made extra pontoons and mounted on the dredging machines to ensure safety.
