Rigging hardware refers to the specialized equipment used to secure, lift, and move heavy loads. Whether you are working in construction, shipping, heavy manufacturing, or theater, utilizing the correct hardware is critical for operational safety and structural integrity. Below is a comprehensive breakdown of the essential components used in professional rigging systems.
These components act as the vital structural links between the load and the lifting device (such as a crane or hoist).
The primary connecting link in any rigging system. The two most common types are Anchor (Bow) shackles, which feature a generous loop to allow for side-loading and multi-leg slings, and Chain (D) shackles, designed strictly for straight-line pulls.
Threaded directly into a load to provide a secure permanent or temporary lifting point. Shoulder eye bolts are preferred for angular loads, while plain pattern eye bolts are restricted exclusively to vertical straight-line lifts.
Used to adjust the tension or exact length of ropes and cables. They feature two threaded end-fittings (hooks, eyes, or jaws) that move closer or further apart when the central body is rotated, providing precise tension control.
Slings are the flexible materials that wrap around or attach directly to the load being lifted.
Made of tightly braided high-strength steel wires. They are extremely durable, heat-resistant, and boast an excellent strength-to-weight ratio, making them a staple in heavy construction and marine environments.
Manufactured from high-tenacity nylon or polyester webbing/yarns. They are lightweight, highly flexible, and will not scratch, crush, or damage delicate or finished surfaces during a lift.
Constructed from high-grade alloy steel. They are utilized in the most rugged and demanding environments (like foundries or steel mills) because they are highly resistant to severe abrasion, sharp edges, and extreme heat.
These mechanical components manage the direction of the lifting force and form the final connection to the hoist or crane.
Feature a U-shaped attachment point equipped with a secure load pin, making them incredibly easy and fast to attach directly to alloy lifting chains without the need for additional connecting links.
Engineered with a bearing or bushing that allows the hook to rotate 360° smoothly while fully under load. This critical feature prevents the wire rope or chain from twisting, kinking, and accumulating dangerous internal stress.
A heavy-duty pulley block designed with a side plate that can open up. This allows a wire rope to be threaded over the sheave without removing the end fitting. They are used to change the direction of a pull or create a mechanical advantage.
