Abstract

1359828 Dredgers C E McKAY and G P BARKER 20 July 1971 [11 Aug 1970] 34047/71 Heading E1F Pivotally supported from the hull of a dredger is a ladder comprising a plurality of sections that are pivoted together for relative swinging movement in a vertical plane and are supported from the hull by winch-controlled block and tackle systems, and such a ladder provides support af its lower end for excavating means and for a suction pipe of rigid sections secured to the ladder sections and coupled to one another in the vicinity of the pivotal connections of the ladder sections by flexible couplings. The excavating means may be a rotary cutter powered by a motor also mounted on the lowermost ladder section and the suction for the pipe may be provided by a hullmounted suction pump that may be aided by booster pumps located on some of the ladder sections. The block and tackle systems may be such as to allow of vertical location of the upper part of the ladder and the winches of such systems may be controlled by the swellcompensating system of Specification 1359829 to maintain a constant relationship between the cutting head and material being excavated thereby irrespective of movement of the hull due to swell conditions.
