Rigging Supplies
Rigging supplies can play a crucial role in successfully moving and transporting heavy loads. The right tools can help to make the entire process much easier and more efficient.
For example, a snatch block is a necessary rigging component that helps to lessen the force needed to lift heavier objects. Other types of blocks include square and swivel blocks.
Eye Bolts
As the name suggests, eye bolts have a loop on one end, which riggers use to attach chains and ropes for lifting or tie-down purposes. They can be screwed into a threaded hole or fastened using a nut. These rigging supplies are typically made of steel or stainless steel for strength and durability. They may also be galvanized for added corrosion resistance in demanding applications, such as marine environments.
There are many different types of eye bolts available to meet the needs of a wide range of rigging jobs. For instance, shoulder eye bolts are designed for angular connections, while straight eye bolts work well with in-line lifts. The rated load limits for eye bolts vary by design, and they must be used in accordance with manufacturer specifications to avoid damage or failure.
Grainger’s selection of eye bolts includes plain, shoulder, and hex styles. The plain version has a plain loop and Silicone Spatulas a threaded shank, while the shoulder pattern has a defined shoulder between the eye and the shank that helps stabilize the bolt under load. Forged eye bolts are significantly stronger than cast or machine parts, and they’re often used in critical applications such as rigging. Stainless eye bolts are also available, which resist corrosion in harsh environments like marine applications and chemical processing plants. Moreover, they’re more economical than eye swivel hooks.
Steel Nuts
When it comes to rigging, there are many different kinds of equipment that are used. It is important to know what you are looking for in order to make sure that you are buying the right products for your job. There are several types of nuts and bolts that can be used as rigging supplies.
Hex nuts are the most commonly used type of nut. These nuts have six-sided threads and are normally tightened using a torque wrench. They are available in a range of sizes to suit different applications. They are also available in stainless steel, which makes them suitable for use in a variety of environments.
Another type of nut that is used as a rigging supply is the jam nut. These nuts are used to provide a secure grip on the hex of the bolt. They are usually made from forged alloy steel and can be used to support heavy loads without the risk of slipping or damage.
Riggers must ensure that their general rigging setup and individual components are not over-burdened, which can cause them to break or fail. This is why it is important to use only the highest quality rigging equipment, which has been tested and rated for specific applications. The rigging equipment should be regularly tried to determine its minimum breaking load (MBL), so that it is not overloaded and damaged.
Rigging Hooks
Rigging hooks are used as attachment points in a wide variety of lifting applications. They’re typically made of carbon or alloy steel and are available in a range of sizes, capacities, and designs. Columbus McKinnon offers a full line of hoist, slip, grab and clevis hooks in various styles to suit your needs.
General rigging hooks feature a U-shaped clevis top secured by a bolt or pin. They’re often used as nonpermanent alternatives to eye hooks by rigging shops and end users that aren’t certified to weld chain slings. Clevis hooks are ideal for a variety of lifting applications, from hoisting machinery to transporting cargo.
Swivel hooks rotate to make it easier for a rigger to position and connect a load. They’re usually designed to be swiveled before adding the load but cannot be swiveled while connected to the load. This type of rigging hook is often used to transport long or bulky loads such as pipe and tubes.
Foundry hooks have a large throat and notched or flattened tip. They’re typically used to handle heavy and bulky loads in foundries and steel Silicone Supplies Manufacturer mills. J-hooks have a narrower throat with a clevis attachment and are typically used in chain sling assemblies or for load binding in transportation applications. Some specialized hooks are able to handle a variety of materials such as plastic, metal or wood.
Chain Shackles
A shackle is a connection link used in rigging that features a loop of steel and a pin. It’s essential for connecting different pieces of rigging equipment and keeping heavy loads from slipping in the air. Shackles are available in a variety of sizes, but it’s important to select one that has a strong working load limit and is made from stainless steel.
Rigging equipment includes wire ropes, chains and other mechanical devices used to secure, move and lift heavy loads on construction or industrial sites. A team of riggers can use these tools to safely transport materials and large-scale fixtures using a crane or hoist.
It’s vital for riggers to prepare themselves for the rigors of their job. They must familiarize themselves with the site where they’re about to work, looking for any potential hazards that could affect their safety. Riggers should also understand the nature of the rigging operation they’re about to undertake.
Rigging involves a complex system of pulleys and ropes to make lifting heavy objects easier. This is often necessary in confined spaces where it’s not possible to get a crane or other lifting device close enough to the object. It’s also a necessity when moving loads in the presence of wind or other environmental factors that can cause problems with traditional lifting methods.
