Anchors with crossbars are rod anchors. The characteristic of this type of anchor is that a claw engages in the soil, and when the anchor is dragged on the seabed, the crossbar can prevent the claw from tipping over, playing a stabilizing role. There are naval anchors, Layman anchors, single claw anchors, and Japanese anchors among the pole anchors.

Navy anchor: It is the most commonly used typical pole anchor, also known as a regular anchor. This type of anchor has a large gripping force and can firmly grasp various soil, but it is inconvenient to retract and release. It is no longer used as a main anchor on modern large ships, but only on sailboats and small inland vessels. It can be used as a positioning anchor for operations on navy lifeboats and engineering ships.

Layermen anchor: It is a naval anchor that can rotate its claws. In use, when one claw enters the soil, the other claw can turn to the anchor handle and stick tightly. This type of anchor is more convenient to use than naval anchors, but its grip is smaller than naval anchors, and only one bolt is used to connect the anchor handle, resulting in poor safety. Therefore, it can only be used on sailboats and inland vessels, and the anchor weight generally does not exceed one ton.

Single claw anchor: Similar to naval anchors, with only one claw, but with a larger size. This type of anchor has a greater claw force than naval anchors. Positioning anchors for various engineering ships, commonly used by dredgers, can ensure that the ship does not move during dredging operations.

Japanese anchor: It is a double claw anchor used on Japanese fishing boats, with a crossbar fixed below the anchor crown. This not only maintains the advantage of high grip, but also facilitates storage
