Rigging Supplies For Lifting and Transporting Heavy Objects

Rigging supplies are used to help lift and transport heavy objects. They should be inspected on a regular basis to ensure that they are safe to use.

These rigging hardware accessories include hooks, eye bolts, wire rope clips and stainless steel nuts. They can be shouldered or non-shouldered and come in different sizes based on the weight of the load.


Eye bolts are essential rigging supplies that provide connection points for lifting, anchoring, pulling and hoisting applications. These devices come in a variety of materials, fabrications, fastening types and shoulder designs. It’s important to choose the right eye bolt for your specific application so you don’t put your equipment, materials or personnel at risk of injury.

The most important measurement for an eye bolt is its rated load capacity. SPEP’s selection of eye bolts carries devices with a rated capacity ranging from 460 pounds to 38,000 pounds per bolt for our most heavy-duty options. It’s also vital to consider the load angle of the eye bolt. Eye bolts without shoulders can only be used for vertical loads, while forged eye bolts with shoulders can handle angular loading as well.

Forged eye bolts are stronger than non-forged varieties and can support up to the tensile strength of the material they’re made from. They’re hammered or pressed to change the composition of the top part of the bolt and are often used in lifting and rigging applications. Non-forged varieties, also known as turned eye, wire eye or bent eye bolts, have a simple loop formed by bending the top unthreaded section of the bolt into its signature shape without creating an endless loop.

Galvanized and stainless steel eye bolts offer protection against corrosion and oxidization. Stainless is ideal for rigging and marine applications because it can withstand harsh environments with saltwater and ocean spray. The galvanization process adds a protective zinc coating to the metal material.


A hook is a piece of metal hardware with a curved or bent back and a deep indentation on one Silicone Utensils end that serves to grab, latch, or in any way attach itself to another object. They are commonly used as rigging equipment for lifting and moving heavy objects in the construction, engineering, and event staging industries.

Blocks and pulleys are also essential rigging supplies that help lessen the amount of force needed to lift weightier items. Blocks, which are available in snatch, swivel, and square varieties, and pulleys, which come in single and double varieties, tend to be combined with rigging ropes in order to hook onto the objects being lifted. They are easy to deploy and available in multiple sizes that range up to 30 tons in capacity.

Rigging shackles, or screw pin and safety shackles, are the connecting links in rigging systems that allow various types of rigging hardware to be quickly connected to and disconnected from one another. They have a hole at one end that can accept screw pins or safety pins to secure the shackle to a chain, wire rope, cable, or other rigging hardware. These shackles are essential for making sure that all components of a rigging system are working together to distribute the load safely and evenly. Like all rigging equipment, these shackles have a specific working load limit (WLL) that should be carefully checked and maintained throughout the lifetime of the product.

Wire Rope

Inexpensive, easy to obtain, and durable, wire ropes are a valuable resource for the rigging industry. They are used to lift, keep secure, pull, and establish tension in a variety of applications, including cranes and hoists. They can also be attached to winches and slings to move heavy loads over long distances.

When using wire rope, it is important to know the different classes that are available. This information can help you determine the best wire rope for your particular application. The class of a wire rope is determined by how many and what type of strands are placed around a core.

The most common type of wire rope, known as general purpose, consists of six strands of 31 wires that are wrapped around a fiber core. This variety is the most versatile and offers high strength and elasticity. Other types of wire rope are designed with a steel core, which resists crushing and is better suited for sheaves and winding drums.

The strands of wire rope are constructed in a specific way to meet the demands of their applications. There are three primary methods for constructing a strand: regular lay, lang lay, and alternate lay. silicone manufacturer Regular lay is used for strands that must be flexible, while lang lay is more rigid and is used in applications where flexing will not be required. Alternate lay consists of alternating regular and lang lay strands, which is useful for special applications.

Steel Nuts

Steel nuts are used in conjunction with eye bolts and come in various sizes. They are typically made of stainless steel or galvanized and can be found with either RH (right-hand) or LH threads. These fasteners can be used with hex bolts, screws, studs and threaded rod to connect metal and wood components. They are also suitable for use in rigging applications where the load will be lifted vertically.

Stainless steel nuts are usually designed to be weldable. They are made up of chromium, nickel alloys that contain manganese, phosphorus, sulfur and silicon. They are available in a wide range of sizes, including hex nuts, dome nuts, wing nuts and lifting eye nuts. The size of the nut required for an application will depend on the weight of the load.

Whether they are being used in a construction project or simply assembling furniture at home, steel nuts and bolts help to make sure that the objects being held together won’t give way. These fasteners are available in a wide variety of shapes and sizes to suit different needs, and they can even be customized with different coatings to make them more durable or more resistant to corrosion. Regardless of the type of nut or bolt, users must exercise great caution when using rigging equipment and always follow manufacturer’s guidelines.
