Mats or matting systems can be used to traverse over and within the lake, pond, or wetland without sinking in the mud. 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.
or large silt pumps to floating excavators and suction dredging equipment. Often the excavator can load or dispose of material without having to reposition. De-Silting a Pond or Lake, Dredging Lakes and Rivers, Aquatic Consultancy. 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 mechanical approach to dredging will involve some form of equipment such as a clamshell bucket and crane, a dragline, which uses a bucket with holes in it which is dragged across the bottom, or excavator dredging that uses something like a backhoe device. 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.
