Human powered lifting mechanism for the hook, at 1.5 times the rated load as the test load test. The hook lifting mechanism for power driven, with 2 times the rated load as test load test. Remove the hook load test, should not have any obvious defects and increase the degree of deformation, the opening should not exceed 0.25% of the original size.

As the name suggests, a bolt-type shackle comes with a bolt, nut, and a cotter pin, making it a secure rigging tool. With a bolt and nut securing the shackle pin, they remain closed even when subject to rotation. These shackles come in different sizes and designs, including Dee and Bow shackles.They are also made from various materials, including stainless steel, carbon steel, and alloy steel. You can find them in construction, shipping, and oil and gas, for securing heavy loads during lifting, towing, and other operations.At Holloway, we offer a wide range of bolt-type shackles. Whatever your rigging needs may be, we've got you covered. Just give us a call!

When rigging and lifting a load, it is important the hook is correctly positioned where the weight of the object listed is applied in the bowl or saddle of the hook. Side, back and or tip loading are conditions that reduce the hook's lifting capacity and can cause damage to the hook (see illustration below).

In 1992 the National Transportation Safety Board (NTSB) commissioned a report to study the causes of wheel separations from medium and heavy duty trucks. The report showed that on average between 750 and 1050 wheel separations were reported in the United States each year. Remarkably the report went on to conclude that “… the leading causes of wheel separations from medium and heavy duty trucks are improper tightening of wheel fasteners…” This is merely one, poignant example of many, illustrating the importance of getting the fastener tightened properly. In fact, one can make the claim that “properly tightened joints seldom come loose”.

The term “Lifting” refers to the activity of moving heavy loads, usually above ground level, using any type of equipment, including manpower and lifting devices such as cranes, derricks, hoists, and other similar devices to support the weight being moved. The term “Rigging” refers to the method or methods of attaching a load to lifting equipment (rope lines, tie-downs, etc.) or the process of attaching a load to a crane for lifting. The rigging process also includes preparing the load (or rig) for movement, typically by securing the load to the hook of the lift line, or to some form of rigging structure that provides support and positioning while the load is lifted into position and during transportation to its destination, where it may be released or unloaded from the rigging system and placed on another piece of equipment, vehicle, container, or storage unit to move to its new location or destination after having been lifted by the rigging system.When the loading is done on land, in a port or dock, the load will usually have to travel a distance from the place where the load was loaded onto a truck or other vehicle to the place where the load will be removed from the truck or vehicle, usually at another dock or warehouse facility.

Many companies consider lifting and rigging work tasks to be high hazard. There are a lot of hazards that accompany lifting any loads with cranes or equipment. It is important to not only understand proper rigging techniques, but also the hazards that accompany this type of work task.Annually about 50 riggers are killed when loads have slipped from the rigging or when the rigging has failed. To protect workers against accident, OSHA has a series of strict rigging requirements. These requirements call for you to maintain rigging equipment, properly train employees, and more.Rigging and slinging should be considered a system, as each component (hook, shackle, cable or chain) makes up the system. Riggers should take care when using rigging and slings. The rating of the shackles utilized should be equal to or greater than the rating of the slings. Each shackle and sling should be individually load-stamped and certified. Only shackles and sling hooks that are load rated by their manufacturer, with a rating appropriate for the load, should be used.

Eye bolts are versatile fasteners commonly used in various industries for lifting, riggin

Used as a lifting or securement point, eye bolts are one of the most popular types of rigging hardware. Just like slings, sling hooks, and shackles, eye bolts come in a number of different designs and configurations. Eye bolts can be used as a connection point for rigging, anchoring, pulling, pushing, or hoisting applications.Although eye bolts are commonly used in industrial applications, they’re also commonly misunderstood or used incorrectly. It can be confusing to understand what type of eye bolt to use for your application in conjunction with your other rigging gear.We get questions all the time about the different types of eye bolts and how or when they can be used—which is why we wrote this article. We don’t want you to guess or choose incorrectly—that could result in a rigging failure that could cause significant damage or injury!

Rope Services Direct is able to supply lifting eye nuts (often called “eyes” in the industry). Eye nuts are suitable for a variety of applications and provide a circular fixture with multiple purposes for lifting operations. Please find below all the product information that you’ll need to know about this type of product. You can also find out more about Rope Services Direct on our About us page.

When using eye bolts, it’s crucial to consider load capacities, material compatibility with the environment, and proper installation techniques to ensure safety and reliability in each specific application. Always follow manufacturer guidelines and industry standards for the correct use of eye bolts.

Selecting the right tool for the job can make a huge difference in productivity and quality of work. There are certain tools whose proper selection and use go beyond making your job faster and easier and actually affect workplace safety.Eye bolts are such tools. For this reason, selecting and using eye bolts correctly can make the difference between a safe work environment and one that puts people’s lives at risk.

Eye bolts are a robust and easy‑to‑install attachment point for other rigging hardware, including slings and shackles. They are among the most widely used lifting and rigging products and play a key role in industrial lifting, hoisting, towing, and anchoring. Used correctly, eye bolts are a safe and durable component in rigging assemblies.  Here, we introduce the various types of eye bolts that are available, what they're used for, and - just as important - what they should not be used for. We'll also explore how to install eye bolts to maximize safety and effectiveness. But first, we’ll provide a high-level introduction to this lifting and rigging hardware.  

The primary differentiation in eye bolt construction is whether they are forged or formed-and-bent. Forged Eye Bolts: These are created by hammering or pressing the formable metal into the loop form of the eye. Forged eye bolts are a stronger and more durable construction capable of withstanding loads up to the tensile strength of the material used. The working load capacity (WLL) of all eye bolts decreases significantly depending on the angle of pull, up to 70% at 45°. 

Machinery eye bolts are one of the most common types of rigging hardware used for lifting or securing machinery and equipment. Like slings, sling hooks, and shackles, eye bolts also come in various designs and configurations, made of different materials, like 304 stainless steel and zinc-plated high-carbon steel.While they're widely utilized in industrial applications, eye bolts are also one of the most frequently misinterpreted and misused pieces of hardware. Their misuse and overuse are unfortunately widespread, and given their importance in overhead lifting, abusing them raises the danger of failure, equipment damage, and injury.In this article, we'll list the do's and don'ts of hoisting a load with eye bolts and some common activities that make their use dangerous.

Eye bolts are one of the simplest and yet most often misused pieces of rigging equipment. There are several factors that must be considered when choosing and installing eye bolts. When eye bolts are used improperly, they can be damaged or broken leading to catastrophic accidents and injuries even when performing fairly basic lifts. 

An eye bolt is a very common and fundamental piece of rigging hardware used to create secure anchor points in various lifting and rigging applications. Their signature design provides easy accessibility for rope and rigging hooks to either loop through or attach to without compromising under serious tension forces. Knowing how to secure these devices, however, is imperative to ensure it functions properly and safely while reducing the risk of breaking, bending, or damaging its surroundings.Read on to know more about eye bolts and their different types, as well as how to use them effectively in the safest ways possible.

The eye bolt (otherwise known as a lifting eye bolt or eyelet) is a type of bolt with a loop at one end. They are used for a wide variety of material lifting applications and may either pivot or swivel. The securing eye must be securely attached to the structure before ropes or cables are tied for lifting. In some instances, there will be a purpose-made hole for the eye bolt. The load may also have to be attached to a hole designed for alternative use, such as the stud.

An eye nut is an exceptional pole line hardware and fastener used for pole line and overhead line construction.When you make a decision to purchase this fastener, always search for one that is very easy to install.You should always search for one that is reliable.As you read this guide, you will be able to learn about installation and application, eye nut manufacturing process, why you need it, types, specifications, and other aspects that are very important.For more details, read on.

The eye bolt is a type of screw that is held securely in place with a corresponding nut. Amazingly, the first type of bolt was made back in 400 BC – and the general design has changed very little over time. An eye bolt is characterized primarily by its rounded opening on one end – known as its “eye.”The “eye” is offered in a variety of diameters and may be welded, forged, or bent into shape. Beneath the eye is the “shoulder” or “skirt”, which is a slightly widened area between the screw and the eye. This slightly thicker design helps to prevent the entire bolt from bending or warping.
