Modern
anchors are made of cast or forged steel, and there are four main types.
①Anchor with rod: The anchor claw and the anchor shaft are usually integrated, and there is a cross bar perpendicular to the plane of the
anchor claw. Rod anchors are mostly double-claw, and some are single-claw. When in use, one claw bites deeply into the soil and has a strong grip, but due to the cross bar, it is inconvenient to store, so it is mostly used for small ships. The main types of rod anchors are naval anchors, single-claw anchors, Foshan anchors, Japanese anchors, etc.
②Rodless anchor: The anchor claw and the anchor rod can rotate at a certain angle relative to each other, and there is no cross bar. When in use, the two anchor claws are engaged in the soil at the same time, which is convenient for anchor lifting and storage, and is the most widely used. The representative rodless anchors are Hall anchors and their modified Speck anchors.
③ Large-holding anchor: the anchor claw is wide and can be rotated at a certain angle, and the anchor head or the middle of the anchor claw has a protruding rod body, which plays a stabilizing role. Due to the large area of the anchor claw to bite the soil and the strong grip, it is suitable for the sandy or soft soil bottom. The main types of high-holding anchors are Danforth anchors, Martens large-claw anchors, and speedboat
anchors.
④Special anchor: The shape is different from the general anchor, such as the mushroom-shaped anchor, the anchor head is in the shape of a mushroom or an umbrella, and it bites deeply into the soil, with a large grip, and is not easy to move. It is mostly used for long-term anchoring and positioning, such as light boats and buoys. , fixed anchors for barges, etc.
