Embodiment Construction

[0018] figure 1 The shown suction dredger comprises a suction dredger having a hull 1 to which a dredging pipe, generally indicated at 3 , is connected to one side wall. The dredging pipe 3 is shown in solid line in its working position, wherein the suction head 4 is lowered onto the bottom 16 of the body of water 17 . The dredging pipe 3 is supported by suspension means 14 having cables 13 for switching the dredging pipe 3 alongside the suction dredger hull 1 between the working position and its substantially horizontal rest position, working location at figure 1 is shown as a solid line, and the rest position is shown as a dashed line. In this respect, the dredging pipe has an elbow 5 which is connected to an opening in the hull 1 of the suction dredger in such a way that the dredging pipe 3 is rotatable about a pivot axis 7 so that Said axis 7 extends transversely with respect to said side walls. Via the propulsion unit 29 the suction dredger and thus the suction head i...

Abstract

A suction dredger comprises a dredging tube (3) which at one end is connected to a suction head (4) and which at the other end is connected to the suction dredger hull (1) by means of a pivot connection (7) having a pivot axis which is horizontally and transversely oriented with respect to said hull (1), and a suspension device (13, 14) by means of which said dredging tube (3) is displaceable between a generally horizontal rest position and an inclined dredging position, said dredging tube (3) comprising a frame (21) and a tube device (20) supported by said frame (21). The dredging tube (3) has a variable length.

Description

technical field [0001] The invention relates to a suction dredger, comprising: a dredging pipe, one end of which is connected to a suction head, and the other end is connected to the hull of the dredger through a pivot connection, the pivot The connecting member has a pivot axis which is horizontally and transversely oriented relative to the hull; and suspension means by which the dredging pipe can be moved between a substantially horizontal rest position and an inclined dredging position The dredging pipe includes a frame and a pipeline device supported by the frame. Background technique [0002] Suction dredgers of this type are disclosed in GB-A-657.289. The dredging pipe of the prior art suction dredger comprises a plurality of sections providing a specific length. Depending on the length of the dredging pipe, a specific dredging depth can be obtained taking into account the maximum inclination of the dredging pipe. Considering that the dredging pipe in the rest posit...
