Trailing suction hopper dredgers are equipped with one or two suction pipes ending in drag heads. Boskalis deploys trailing suction hoppers dredgers for the construction and maintenance of ports and waterways as well as land reclamation and coastal defense and riverbank protection. Mats or matting systems can be used to traverse over and within the lake, pond, or wetland without sinking in the mud.The trailing suction hopper dredgers (TSHDs) of Boskalis are oceangoing vessels that can collect sand and silt from the seabed and transport it over large distances. Long reach excavators are not as efficient or stable with grading projects and standard earth moving so they are a specialized piece that you typically see within a certain type of project. Furthermore, the excavator can place wet, sloppy sediment away from the machine so that you can continue to work while sediment dewaters off to the side. Often the excavator can load or dispose of material without having to reposition. The advantage is that you can move sediment over 100’ in distance in one rotation, which is impressive. It also allows you to relay or place material the same distance from the machine. The extended boom allows the operator to remove sediment from the stable shoreline up to 70’ out into the lake. Larger excavators are the most commonly types and extend a standard range boom from 20-30’ to 50-70’. Typically, small mini and midi excavators can extend the reach along the ground from 12-15’ to 15-25’. The reach of a standard excavator is doubled or tripled with a long reach boom. Long reach excavators are fitted with a longer boom and smaller bucket to enable it to reach a further distance. The most common type is the long reach excavator. River Sand incorporates the use of several types of specialized excavators for its mechanical dredging projects.
