D shackles, also known as chain shackles or dee shackles, are a type of rigging hardware commonly used in the lifting and rigging industry. They are designed with a U-shaped body that has a threaded pin or bolt that can be inserted through the two ends of the shackle to secure a load or connect rigging hardware.
D shackles come in various sizes and materials, including stainless steel, galvanized steel, and alloy steel, to match the load capacity and environmental conditions in which they will be used. They are commonly used in construction, manufacturing, and industrial applications to connect chains, slings, and other rigging hardware, or to secure loads to a crane or other lifting equipment.
To ensure safe and efficient use of D shackles, it is important to select the right size and material for the load and environmental conditions. It is also essential to properly inspect the shackles before each use for any signs of wear or damage, such as cracks or deformations, that could compromise their strength and integrity. Additionally, users must follow proper rigging techniques and safety protocols to prevent accidents and ensure the safety of themselves and others.
