Abstract

PURPOSE: To facilitate dredging works even in narrow waters, by fitting a dredging ladder through a swivel board on the front edge of a dredger hull so that the ladder swing is independent from the hull.
CONSTITUTION: A swivel board 21 having a segmental gear 21a is driven by a hydraulic motor through gears 25, 26. The base of a dredging ladder 31 is fitted below the swivel board 21 through a horizontal shaft 32 to horizontally turn the ladder together with the swivel board 21. A cutter head 33 at the tip of the dredging ladder 31 is driven by a cutter motor 34. The number 35 in the figure represents a hydraulic cylinder for elevating the ladder.
