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.
