хорошо ведро цепь земснаряда с высокой эффективностью

Bucket ladder dredgers are able to dredge almost any material up to the point where blasting is required, and if fitted with ripper teeth may even be directly able to dredge weak rock. A minimal amount of water is added to the dredged material during careful use of the buckets. This is advantageous to production and costs, especially when dredging in silt and mud. In operation, a bucket ladder dredger is held accurately in position by up to six moorings or anchors and the bucket ladder moved from side to side to excavate material. The mooring wires can obstruct other shipping, and high noise levels are a common problem if special steps are not taken to control sound emissions. Much of the power of a bucket dredger is used in turning the chain, but the high inertia of this can also assist in overcoming localized hard spots. The maximum weekly output of a bucket dredger can vary between 10.000 and 100.000 m3 (in-situ) depending upon size, location and material. Maximum dredging depths are normally around 20 m. Bucket ladder dredgers are complex and expensive machines to operate but can dredge to the required depth very accurately.
