Correct Use Of Anchor Shackles

Shackles are a very widely used connection tool. It can be used to connect various cables and chains, as well as anchors and anchor chains, and can also be used to fasten cables and chains to devices such as deck eye rings (plates). Anchor shackle is a type of marine rigging used to connect anchor chains and sinkers. Shackles are widely used because of their small size and large load-bearing capacity. According to type, it can be divided into G209 (BW), G210 (DW), G2130 (BX), G2150 (DX); according to type, it can be divided into bow type (Omega type) bow type with female shackle and D type (U type or straight type Type) D type with female shackle; according to the place of use, it can be divided into two types: marine and land use.

There are many kinds of anchor shackles, divided by shape, there are straight and round shackles; according to the scope of use, there are differences between anchor chain shackles and sail cable shackles; according to the type of horizontal pins, they can be divided into screw thread pins There are two kinds of shackles and light direct pin shackles. The light direct pin shackles are fixed with cotter pins. There are also special-purpose fiber ropes and special-purpose steel cables in the sail cable shackles. Shackles used for fiber ropes, the inner diameter of the ring is larger, usually round shackles are mostly used for fiber ropes.

The shackles used to connect anchors, anchor chains and buoys on large ships are mostly special shackles.

The anchor shackle is a shackle used to connect the anchor chain and the sinker. When using, the horizontal bolt should be upward (buoy direction). The cross-bolt is rounded so that it cannot rotate in the bolt hole and increases its strength. When using, first take out the horizontal bolt of the shackle, put the "U"-shaped buckle into the large anchor chain ring to be connected, and then connect the horizontal bolt in series with a large anchor chain ring above. In order to prevent the cross bolt from coming out, there is an inclined hole at the two ends of the cross bolt and the "U"-shaped buckle for driving the brake inclined pin. In order to prevent the oblique pin from coming out, a green lead seal should be punched into the hole left at the pin hole. Calcium-based grease should be applied before the inclined pin is inserted into the pin hole for rust prevention.
