Types of Rigging and Lifting Supplies
If you are working in the rigging and lifting industry, it is important to choose equipment that is rated for your load weight. This will ensure that your workers are safe and that the equipment does not fail.
There are a variety of different types of rigging equipment. Some examples include slings, hooks, and shackles.
Eye bolts
Eye bolts are used in a variety of rigging scenarios and provide an attachment point for slings and cables. They are commonly made from forged steel and consist of a circular eye at one end and a threaded shank that can be screwed into a structure or object. Some types of eye bolts, such as shoulder bolts, have an additional shoulder lifting and rigging supplies or collar to reduce bending forces during use. They are typically used in applications where angular loading is expected.
Rigging professionals should use the right type of eye bolt to ensure the safety of their workers and equipment. They should also follow manufacturer guidelines and industry best practices when using these tools. It is important to inspect eye bolts before and after each use for signs of wear or damage. Incorrectly sized or installed eye bolts can result in serious accidents.
When selecting an eye bolt for a particular application, it is important to consider the load capacity and the environment where it will be used. The working load limit (WLL) of the bolt must be sufficient to support the expected load and any accompanying rigging components. In addition, the eye and shank must be free of bends and distortions. It is also important to check that the bolt has not been altered in any way, including grinding, machining, stamping, or burning.
Rigging hooks
Rigging hooks are used to secure a load and eliminate the risk of slippage. They come in many different designs and sizes for lifting various types of loads. They are categorized by the size of the hook opening, also called throat, and are rated for different capacities. Some examples of rigging hooks include C-hooks, ramshorn hooks, and claw hooks. In addition, it is important to note that a hook’s working load limit (WLL) is reduced if the hook is subjected to side, back, or tip loading. To prevent this, it is important to inspect a rigging hook regularly and replace it when necessary.
Positioning swivel hooks are designed to swivel to allow the rigger to align the hook with the load, but they cannot swivel while under load. This type of hook can help to reduce the chances of the sling twisting and should be used in applications where it is not necessary for the rigging equipment to swivel while under load.
Self-locking hooks have a spring release trigger that closes when it is under load. They are ideal for top loading and applications with chain slings, as they provide extra security when attaching and detaching a load. Foundry hooks have wide and deep throat openings that can fit trunnions and handles on castings and molds in foundries. These hooks are typically used without a safety latch, as it would be unsafe for workers to reach up and connect or disconnect a load in these high heat environments.
Stainless steel nuts
Stainless steel nuts are a crucial part of many construction projects. They are durable, resistant to high temperatures, and able to hold heavy loads. They also resist corrosion and are highly versatile. This makes them a great choice for use in projects that involve harsh environments or in areas that are exposed to chemicals and salt water. Stainless steel nuts are available in a wide range of sizes, types, and finishes. Some are coated with a black oxide finish or zinc chromate, while others are non-magnetic.
The most common type of stainless steel nut is the hex nut, which has a hexagonal head and a threaded shaft. It is used to connect metal and wood components in industrial machinery, and it can be found in many different sizes. Other types of stainless steel nuts include shoulder bolts and socket cap screws. These fasteners are used in a variety of applications, including machine building and automotive work.
There are also a number of specialty types of stainless steel nuts, such as screw eyes and threaded eyebolts. Screw eyes have a head shaped like an eye, and they are commonly used for lifting and rigging applications. They can also be used to guide wire or cable. Threaded eyebolts have a threaded shank that is installed flush with the head, and they are often used in applications where a high load capacity is required.
Safety equipment
Safety equipment is a must for workers who use lifting and rigging supplies. It prevents sprains and other serious injuries while on the job. It can also help prevent damage to the load and equipment. Employers are responsible for providing all the necessary safety equipment to their employees and making sure they know how to use it correctly.
Rigging equipment is used to move heavy loads and secure them during transport. It includes different types of ropes, chains, shackles, and turnbuckles. It is essential to make sure all the rigging gear can support the weight of the load and is regularly inspected.
When choosing rigging hardware, be sure to consider its working lifting and rigging supplies load limit (WLL). The WLL of each product should not be exceeded. If you are looking for a specific product, be sure to contact a product expert to find out its rated capacity. Avoid using shackles with elongated pin holes, surface blemishes, or distortion in the eye or shackle pin. Also, choose double clevises for use with proof coil chain and avoid angle loading on non-shoulder bolts.
Rigging is a process of attaching and securing a load to cranes and other lifting equipment for transport. It is a complex task that requires proper training and experience to complete safely. Using improper equipment can lead to injury and property damage, so it is important to hire qualified personnel for this type of work.
