Shackles Information & Use Limitations

Shackles are one of the most used rigging fittings. Because the removable pins, they are used to make connections to wire rope, chain and other fittings.

They have a wide variety of styles and types, and with so many different options, choosing the right shackle for the job can be confusing. Therefore, we summarized some of the basics below.


Shackles Information & Use Limitations


Bow vs. D shackle


Shackles Information & Use Limitations


Bow shackle and anchor shackle are usually used interchangeably, it refers to a shackle with a larger, rounded ''O'' shape look. The rounded design of bow shackles allows them to take loads from many directions without developing significant side load. The larger loop shape of the bow shackle does reduce its overall strength, but it is also able to handle a larger strap.


Shackles Information & Use Limitations


D shackles are also known as chain shackles or dee shackles. Both refer to the letter “D” shape design. A d shackle is narrower than a bow shackle and generally has a threaded pin or pin close. The smaller loop is designed to take high loads primarily in line. Side and racking loads may twist or bend a D shackle.

Both bow and d shackles come with different pin options as well.


Galvanized shackles vs. stainless steel shackles

Galvanized metal and stainless steel both offer excellent protection from rust and corrosion, making either a great choice.


Shackles Information & Use Limitations


In general, galvanized shackles are ideal for industrial applications where moisture is not a major issue. Galvanized steel has a thin coating of zinc oxide to protect the steel from elements that lead to corrosion and oxidation. Galvanized is also a great choice as it tends to be less expensive than stainless steel, but still maintains the shackle’s strength and durability.


Shackles Information & Use Limitations


Stainless steel shackles are more corrosive-resistant and, therefore ideal for marine applications. Our stainless steel shackles are made of 304 or 316 stainless steel. AISI 316 stainless steel is also considered ''marine grade.'' It contains molybdenum, which makes it resistant to ocean water mist or spray, so it's especially useful in extreme conditions or moisture or in a high chloride environment.


Pin types

The pin that locks a shackle can be a deciding factor on which shackle will work best for your job. We carry shackles with round pins, square head pins, screw pins, and bolt-type pins.


Shackles Information & Use Limitations


Round Pin Shackles can be used in tie-down, towing, suspension or lifting applications where the load is strictly applied in-line. Round pin shackles should never be used in rigging applications to gather multiple sling legs or where side-loading conditions may occur.


Shackles Information & Use Limitations


Square Head Pin Shackle also called a Trawling Shackle. These trawling shackles are commonly used in the marine industry for trawling purposes during fishing expeditions.


Shackles Information & Use Limitations


Screw Pin Shackles are popular because they offer a pin that is easy to connect and disconnect. Screw Pin Shackles are used in Pick and Place* applications. Screw pin shackles can be used for applications involving side-loading circumstances. Reduced Work Load Limits are required for side-loading applications. While in service, do not allow the screw pin to be rotated by a live line, such as in a choker application.


Shackles Information & Use Limitations


Bolt-Type Pin Shackles can be used in any application where round pin or screw pin shackles are used. In addition, they are recommended for permanent or long-term installations where the load may slide on the shackle pin causing the pin to rotate. The bolt-type shackle’s secondary securement system, utilizing a nut and cotter, eliminates the requirement to tighten the pin before each lift or movement of the load.

With a variety of dee shackles for straight pulling, bow shackles for multi-dimensional pulls, and many more stainless steel shackles, we have the equipment you need to get the job done.


Shackle Loading

The Working Load Limit on a shackle varies according to the angle of the load.


Shackles Information & Use Limitations


The pre-use check for shackles should ensure that:


Shackles Information & Use Limitations


  1. The body of the shackle and pin are both compatible and are of the same grade and material.

  2. All markings are clearly legible.

  3. The pin is the correct type for the shackle body.

  4. The threads of the pin and the shackle body are in good order and function correctly.

  5. The body and pin are not damaged in any way and are free from distortion, nicks, gouges, cracks and excessive wear and corrosion. (Recommended maximum wear allowance is 10%).

  6. For 'Safety pin' shackles ensure that the nuts and split pins are fitted and in good condition.


Warning:

  • Incorrect shackle use could result in a dangerous situation that could cause property damage, serious injury or death.

  • When using shackles in multi-leg slings, due consideration should be given to the effect of the angle between the legs. As the included angle increases so too do the load in the sling leg and the shackle.

  • Shackles should never be used on a sling with an included angle in excess of 120˚.
