How to make the dredging ship complete left and right lateral movement during work

Do you know how to make a dredging ship move laterally when working underwater? To allow the dredging vessel to move laterally, a lateral device system needs to be installed. The function of the lateral movement device is to make the dredger swing left and right during construction. The lateral movement device is composed of the following parts: Do you know how to make the dredging ship move horizontally when working underwater?

To allow the dredging vessel to move laterally, a lateral device system needs to be installed. The function of the lateral movement device is to make the dredger swing left and right during construction. The lateral movement device is composed of the following parts:

1. Horizontal winch: operated by the driver of the dredging ship, the horizontal winch produces forward and reverse rotation, which plays a retracting and releasing role on the horizontal winch. When the dredging ship needs to swing to one side, tighten the lateral cable on that side and loosen the cable on the other side; The reverse is also true.

2. Horizontal cable: It is a steel wire rope, with one end connected to the horizontal winch through an underwater guide pulley and the other end connected to the horizontal anchor. The length is about three times the length of the ship's hull and must be a complete piece to facilitate passage through underwater pulleys and access to the transverse winch.

3. Guide pulley: connected to the cutter bridge, it plays a directional role in the lateral movement of the cable.

4. Horizontal anchor: thrown outside the excavation section as a fixed support point for the horizontal anchor. If the length allows, it can be thrown further to control the migration distance of the dredger. The lateral anchor is projected through an anchor boat or anchor rod. When the dredger is too shallow on both sides to anchor, ground anchors can be buried on the shore to fix the support points.

5. Anchor lifting rod: commonly used on new suction dredgers and installed on both sides of the bow. The driver completes the work of throwing the lateral anchor through operations on the bridge, reducing the workload of the anchor boat and the labor intensity of the crew.
