They also have relatively high noise levels. They are less frequently used because they have relatively low production rates and need to have anchor lines, which often interfere with navigation traffic. ![]() Limitationsīucket ladder dredgers have been almost entirely replaced by backhoe dredgers or trailing suction hopper dredgers and cutter suction dredgers. This includes certain specific tasks, such as removing stiff clays and weak rock layers, trench dredging and maintenance in some ports. Types of materialīucket-ladder dredgers can be effectively used for dredging a wide variety of materials up to and including soft rock. The bucket-ladder dredger is usually stationary but some are self-propelled and can travel on their own to the dredging site. Rock bucket dredgers may have a double set of buckets: a small rock bucket and a bigger soft soil bucket. As with other mechanical dredgers, barges or scows are used to transport the dredged material to the placement or relocation sites.īucket sizes vary from 30 liters to 1200 liters. ![]() The material is then sent through the chute to barges or scows alongside the dredger. At the top the buckets rotate into an upside down position and their contents falls into a chute. ![]() The loop of the bucket-ladder dredger is powered causing the buckets to travel downwards in such a way as to scoop the material from the bottom, and then carry the material in the upright buckets up the ladder to the top.
