Abstract

1333394 Suction dredgers INDUSTRIEELE HANDELSCOMBINATIE HOLLAND NV 12 July 1971 [22 July 1970] 32577/71 Heading E1F In a dredger having a cutter at the lower end of a cutter and suction pipe-carrying ladder 2 pivotally mounted at the forward end of a pontoon 1 anchorable by a spud 10 vertically and rotatably mounted on the stern of the pontoon by a guide element 9 pivotally secured to the stern at 8 maintainence of the cutter in a desired operating position on the sea bed without disturbance by the movement of the hull due to wave conditions is facilitated by connecting the ladder to the spud by a parallelogram linkage 1, 4, 6, 7. The strut 4 is pivoted on the pontoon, is connected to the ladder by a strut of fixed or adjustable length and is connected by a strut or a cable 6 to either a second strut 7 secured to the guide element 9 or to the upper part of the spud. A jack can be provided for yieldingly applying a constant force 11 against the strut 7 to keep the element 6 in tension.
