WHAT IS A DIPPER DREDGER? ITS TYPES AND WHO TO CONTACT FOR HIRING ONE
Introduction The dipper dredger is typically a barge-straddling power shovel. It comes equipped with an energy-driven ladder structure and operates from a barge-type hull. This system is used to accurately remove the required seabed material. In order to maximize the digging power, the dipper dredger is secured on motorized spuds that transmit the weight of the of the dredger down to the seabed. Dipper dredgers typically hold a bucket capacity of 8-12 CU YD, and operating depth of upto 50ft. While, there’s a significant variability between the production rates, 30-60 cycle/Hr. is usually attained.
There are multiple uses of dipper dredgers, but the best uses of all are for the excavation of compacted, hard materials, rocks and other solid items. This can be used for the removal of most bottom residues; the operation of this equipment may lead to a considerable sediment turmoil and buildup during the excavation of fine-grained material. The dipper dredgers are effective around docks, bridges, pipeline, wharves, breakwater structures or piers because they do not require much area to maneuver. There is little or no danger of inadvertently causing unwanted damage to the seabed as modern dredgers utilize GPS technology and are possible to control to a high degree of accuracy. Dredgers must operate in conjunction with barges for the containment and transport of dredged materials. A suitable and approved area will also need to be identified for the disposal of such material.
