With so many types of shackles available in the market, choosing the right one for the job can be confusing. They are available in different configurations and designs.
Likewise, lifting shackles come in various forms. To help you with your research, here are some basic differences between the most common types of these shackles.
Different Shackles for Lifting in Load Handling
Shackles are U-shaped connecting devices ideal for a number of rigging and load securement applications. They help connect different types of chains, wire ropes, and lifting slings to an object or to each other. Here are some commonly used shackling devices.
Anchor shackle
Also known as bow shackles, this connecting device features an O-shaped design that has a more defined bow area. It allows you to move loads from many directions without worrying about sideload damage.
Chain shackle
Commonly referred to as D-shackles, this connecting device is narrower and thinner in form. It features a threaded pin, although there are many options available. It’s ideal for handling sideloads since it has a smaller loop.
Stainless Steel versus Galvanized Steel
To ensure durability, lifting shackles are either made from galvanized metal or stainless steel to prevent rust and corrosion. Perfect for industrial applications, both fabrications offer unique benefits, such as:
- Galvanized shackles best suit environments where moisture levels are low. The material features a zinc oxide coating that protects the steel from the elements. It has a corrosion-resistant body that enhances strength and durability.
- Heavy-duty shackles made from stainless steel are ideal for marine operations. This is because the material contains molybdenum, a chemical that’s resistant to salt water or spray. The material can also withstand extreme environments.
Types of Lifting Shackles
Though shackles provide fastening for a range of industrial jobs, it’s not always easy to find a fitting that suits the application. Here are some commonly used lifting shackles:
- Swivel eye snap shackles feature a spring-activated mechanism that is easy to use and quick to assemble. Such shackles are ideal for jobs where speed is necessary so you can connect and disconnect with efficiency.
- Pin-type shackles include captive, round, bolt-type, loose, and captive pins. They are ideal for permanent and temporary applications. For instance, captive pin shackles in marine applications.
- Bolt-type shackles are popularly used for heavy-duty securement. They come in a variety of colors and weight limits, making them perfect for live event rigging. Ankle shackles are an excellent option for securing multi-leg slings.
- D-shaped shackles are ideal for single-leg slings, often resembling the loop of a chain. Also known as chain shackles, this connecting device does not support sideloading. Engineered to withstand in-line stress, it joins objects rated for in-line tension.
