Types of Rigging Hardware

Rigging hardware refers to a wide range of components used for lifting and supporting objects. They include pulleys, blocks, clevis hooks, spreader bars and shackles. These are commonly used in various industries, such as manufacturing, construction, transportation and utilities.

Eye hooks

Eye hooks are one of the most popular types of rigging hardware. They are typically used with tie down equipment, and they provide a safe way to attach your load to a rigging point. However, misuse and misapplication of eye bolts can increase the risk of injury or damage.

If you are looking to purchase eye hooks, it is important that you choose a good quality piece. Make sure you check the size, rated capacity, and condition of the item before buying. Never use an eye bolt that is worn or in poor condition. You must also consider the weight limit of the object. It is possible to exceed the rated capacity of an eye bolt, which can cause the rigging assembly to fail.

Eye bolts come in several different designs. There are nut eye bolts, screw eye bolts, and shoulder eye bolts. Regular eye bolts are commonly used in industrial applications.

Shoulder eye bolts are used for angular lifting. These eye bolts distribute the lifting force over the entire shank. This helps to prevent the shank from bending. When using eye bolts for angular lifts, it is important that the eye is seated properly.

If you are in need of eye hooks, look for a high-quality manufacturer. Crosby is a trusted name in the industry.

Before purchasing an eye bolt, it is recommended that you consult with your Product Advisor. He or she will help you find the perfect eye bolt for your application.

Clevis hooks

Clevis hooks are a heavy-duty rigging accessory used to attach a chain or sling to a load. They can support loads up to 6,000 pounds. While they may not be as flexible as an eye hook, they provide a number of benefits, including ease of installation and quick replacement.

These sling hooks are a great choice for towing, transporting, and oil & gas pulling. Their self-locking design prevents the hook from opening or accidentally dislodging, which would allow it to fall off. Despite their flexibility, they do not rotate under load like an eye hook.

There are two primary types of clevis hooks: swivel and snap-lock. The latter is a locking mechanism that adds an extra level of security to lifting. In the swivel category, the pin that connects the hook to the chain can move from side to side. This is the same principle behind the snap-lock, but the locking mechanism is only capable of working in one direction.

While they have a long list of functions, the best clevis hooks have a few things in common. First, they offer a wide throat that allows the rope to pass through without slack. Second, they have a U-shaped opening, which is ideal for attaching the chain to a rigging attachment. Lastly, they have a clevis pin that locks the chain to the rigging attachment.

All in all, clevis hooks are an excellent choice for many businesses. Whether you’re looking for a swivel or a snap-lock, you can find them in the right size and style.

Shackles

In order to secure rigging setups, it is important to use the right kind of shackles. Choosing the wrong type of shackle could lead to serious injuries. However, by understanding the different types of shackles and their uses, you can find the perfect one for your specific rigging application.

There are two main shackle types – bolt and screw. Bolt shackles are ideal for long-term installations. They are very strong and are very stable. These shackles are ideal for offshore applications, and for marine lifting. Screw shackles are used for quick connections and disconnects.

When choosing a shackle, it is important to look at the rated load. This will allow you to compare the shackle’s capacity to other rigging hardware. It is also useful to look at the working load limit. The working load limit is the maximum load the shackle can bear without compromising its safety.

In addition, it is important to ensure the shackle has sufficient ductility to deform without losing its ability to support the load at specified temperatures. Also, Rigging Hardware the strength of a shackle can be affected by chemically active environments. You may want to consult with your shackle manufacturer.

A shackle should be checked before each use. Check for threads, and make sure the shoulder is in contact with the shackle body. If the pin cannot be fully threaded, it should be removed.

To make a permanent connection, you will need to install the shackle’s pin. There are several types of pins. Some are suitable for overhead lifting, while others are for pick and lift applications.

Blocks

Blocks are assemblies of parts that have a specific purpose. They can be either fixed or moving, and are often suspended by hoist ropes. There are several types of blocks, and each has its own unique features.

A block and tackle system consists of two pulleys and rope, and is commonly used on boats and cranes. It is also used on drill rigs. The mechanical advantage of a block and tackle system is determined by the number of supporting rope sections. For instance, in a double tackle system, a single rope supports four ropes, which provide a total of 100 N.

Another type of block is the snatch block. It is a heavy-duty pulley designed to lift loads. Snatch blocks have an opening feature, which allows for the sheave to be inserted anywhere along the wire rope. Also, snatch blocks have grease zerks, which help to eliminate friction.

In general, the ball bearings in a block are ideal for fine tuning under load. Ball bearings are constructed of multiple small diameter spherical balls. When spun by hand, a whizzing sound can be heard.

Another feature of a snatch block is its swivels, which prevent side loading. These blocks are a good solution to many line routing problems. However, they are not suitable for constant service.

All blocks should be inspected before and after use to ensure they are in compliance with ASME B30. To verify that they are the correct size, make and model, each block should be marked with its rated load and manufacturer.

Pulleys

A pulley is one of the most important pieces of hardware in your rigging kit. It provides the necessary support to a rope and ensures a good grip on the climbing surface.

One of the most important uses of a pulley is the ability to reduce the force needed to Rigging Hardware lift heavy objects. For instance, when lifting a chain or wire rope, a pulley will loop through it, thus reducing the amount of force required.

Another notable feature of a pulley is its ability to redirect a winch line. This is particularly useful in a pinch as it allows rigging professionals to off-set an anchor point. These are also a handy way to direct a sling or chain to a specific point.

Pulleys can be found in a wide variety of designs and capacities. The best option for you depends on your particular rigging need. Some of the most popular options include the snatch block and the omni block.

A snatch block is a forged steel casing that features a sheave. Sheave is usually a slat, but sometimes the sheave is made of metal. This type of pulley is most likely to be used in conjunction with a winch.

There are a number of other types of rigging hardware, including the snatch block, the snatch sling, and the snatch block sling. These can be used to lift heavy loads, and are usually manufactured from stainless steel or aluminum.

Spreader bars

Spreader bars are used to lift heavy loads without damaging machinery or people. They are manufactured to withstand the stress of heavy loads and to distribute load weight evenly.

In order to operate spreader bar safely, it is important to follow the manufacturer’s instructions. The instructions should include safety procedures, rigging requirements, and other operating information. Also, visual inspections should be conducted during the process.

Before you start using a spreader bar, check the condition of all equipment. For example, check if there are missing bolts, worn attachment points, or loose chains. If you notice any of these problems, discontinue using the bar.

When rigging hardware, it is also a good idea to ensure the safety of your crew and the rigged load. Even load distribution is a key element to preventing tipping, spinning, and other accidents.

Using a spreader bar in your rigging projects is a great way to keep a load slings vertical. However, it is best to avoid using it for sliding or side pulls. This type of load may also lead to damage of property and injuries.

To properly use a spreader bar, you must attach it to a telehandler or crane. You can use two or four slings to suspend the bar. Use locking pins and safety chains to ensure that the bar is correctly attached to each fork.

Spreader bars are designed to not bend because of their large tension force. This makes them ideal for lifting long, narrow cargo that is held horizontally.
