An industrial D shackle, also known as a chain shackle or simply a shackle, is a type of load-bearing connector commonly used in industrial settings for lifting and rigging applications. It consists of a U-shaped metal loop (the bow) secured by a removable pin or bolt, with a straight piece (the pin) that passes through the bow to create a secure, load-bearing connection. The D shackle is so named because of the shape of the bow, which resembles the letter "D". It is designed to be used with chains, ropes, or straps, and is commonly used to connect these components to a lifting or rigging point. D shackles come in a variety of sizes and load capacities, and are typically made from high-strength materials such as carbon steel, alloy steel, or stainless steel to provide maximum strength and durability.
D shackles are commonly used in industrial settings such as construction sites, shipyards, and manufacturing plants, and are an essential component of many lifting and rigging systems. They are typically used in conjunction with other hardware such as hoists, cranes, and slings to provide a safe and secure means of lifting and moving heavy loads. It is important to select the appropriate size and load capacity of D shackle for the specific application to ensure safe and effective operation.
