A set of BK-Barge with LRA excavator is available for the narrow and muddy dredging area where the excavator can't work.
Also, even in the dredging area where the distance between discharge area is too far to use HDPE Pipe but still need excavator for dredging, a set of BK-Barge with LRA excavator can be applicable.
Though the LRA excavator is mounted on the BK-barge, it still can move in the dredging area by sliding
the whole set by controlling its arm.
