Product Details
A bucket dredger is equipped with a bucket dredge, which is a device that picks up sediment by mechanical means, often with many circulating buckets attached to a wheel or chain. Some bucket dredgers and grab dredgers are powerful enough to rip out coral to make a shipping channel through coral reefs. Area of application Bucket dredgers are only used in new or maintenance dredging projects when the initial depth of the area to be dredged is too shallow for trailing suction hopper dredgers and the distances involved are too long for hydraulic transport. For environmental projects, which require the dredging of `in situ densities`, the bucket dredger is suitable peace of equipment. When dredging for construction materials such as sand and gravel, or for minerals such as gold and tin ores, bucket dredgers are still frequently used. Bucket dredgers also come in a variety of types. For example: Dredgers with or without the means of propulsion (Figure 6- 3) Dredgers with a conveyor belt system (Figure 6- 4) Dredgers with equipped with pumps The maximum dredging depth is highly dependent on the size of the dredger. There are dredgers with a maximum dredging depth of more than 30 metres. Such large dredgers the minimum dredging depth is often 8 metres. Dredging in shallow water is certainly not the strongest point of the bucket dredger. Bucket dredgers can be used in almost every type of soil, from mud to soft rock. When rock has been fragmented by blasting, bucket dredgers are often used, because of their relative lack of sensitivity to variations in the size of the stones. Bucket dredgers cannot be used in areas with waves and swell. Furthermore, because of the amount of noise they produce, in urban areas they are often subject to restrictions in relation to the working time or the permitted number of decibels measured at a specific distance from them.
