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.

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.  

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 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.
