chain shackle vs anchor shackle (bow shackle vs d shackle)

Anchor Shackles / Bow Shackles

The terms anchor shackles and bow shackles are both used interchangeably, feature a large rounded shape that increased area on the inside of the shackle body and allows them to take loads from many directions without developing significant side load. That makes them ideal for use with multiple-leg slings, connecting slings to load rings, and accommodating a wider strap.

Chain Shackles / D Shackles

Chain shackle is referred to as D shackle/Dee shackle, due to the “D” shape design body. “D” (chain) shackles are generally used to join two pieces rated for in-line tension, while bow (anchor) shackles are typically employed where more than one attachment has to be made to the body, for side and racking loads may twist or bend the chain shackle.

Shackle Pin Types: Screw pin shackles vs Bolt type shackles

The shackle pin types are the deciding factors on which shackle will work best for your application.

Screw pin shackles are suitable for quick-to-assemble to connect or disconnect the two-component items, for you can easily and quickly thread the pin insert through the ears and tighten it down. They can be used with little risk of the pin becoming unscrewed during the lifting operation and are not recommended for permanent or long-term installations.

Bolt-type shackles are also referred to as safety pin shackles, for the combination of a bolt/nut/cotter pin and the split retaining pin cannot unscrew in service, it is a more secure choice than screw pin shackle, and can be used in any application especially in lifting purposes that use a round pin or a screw pin.
