The electric combined windlass is a key safety equipment for ships and marine engineering equipment. In order to ensure the high reliability and advanced nature of the windlass, the selection of the system is made of domestic or international high-quality brand-name components, and the windlass is installed on the main deck of the ship's fore and stern. It is used when the ship is used to lift the left and right anchors, drop anchors, and moorings on the left and right sides of the ship. Anchor windlasses are manpower, electric, hydraulic, diesel-powered, etc. according to the method of anchoring. According to the installation and layout methods, they are divided into three types: horizontal, vertical, and drop-in types. The technology is updated, the quality is better, and the service is better. Horizontal windlasses are generally used on commercial ships. Vertical windlasses are generally called anchor winches on commercial and official law enforcement boats or cruise ships and barges with small deck area.
