What is rigging hardware

Rigging Hardware refers to the equipment used in conjunction with ropes, such as hooks, turnbuckles, cable clamps, loops, shackles, etc., collectively referred to as rigging, and ropes are also classified as rigging. Rigging mainly includes metal rigging and synthetic fiber rigging. A general term that includes each mast, mast (mast cross), girder (foot pole), slanting girder, and all cables, chains, and appliances used to operate these
 
The rigging hardware industry has developed rapidly in recent years, but the technical standards are very imperfect. Enterprises produce at will, and even lower the safety factor without authorization. Therefore, there are great hidden dangers in hoisting safety. For example, many countries do not have standards for the transportation of lashing belts. There are only promotion standards for slings, and there are no mandatory standards.

 
Classification of Rigging Hardware
 
Rigging mainly includes metal rigging and synthetic fiber rigging.
 
Metal slings mainly include: wire rope slings, chain slings, shackles, hooks, lifting (clamp) pliers, magnetic slings, etc.
Synthetic fiber rigging mainly includes: rope and belt rigging made of nylon, polypropylene, polyester, and high-strength and high-modulus polyethylene fibers.
 
Application of Rigging Hardware
 
Rigging includes: D-ring, safety hook, spring hook, tight rigging, link double-ring buckle, American ring bolt and other applications.
 
Rigging is widely used in ports, electric power, steel, shipbuilding, petrochemicals, mining, railways, construction, metallurgy and chemicals, automobile manufacturing, engineering machinery, paper machinery, industrial control, logistics, large-scale transportation, pipeline auxiliary equipment, maritime rescue, Important industries such as marine engineering, airport construction, bridges, aviation, aerospace, venues, etc.
 
Common rigging
 
The Shackle Of Rigging Hardware
 
Shackles are detachable circular metal components used to connect various rope eye loops, chain links and other rigging. The shackle is composed of a body and a horizontal bolt. Some horizontal bolts are threaded, some are pinned, and the common ones are straight shackles and round shackles. Shackles are often named according to the parts used, such as anchor shackles used on anchor rods; chain shackles used on anchor chains; and rope head shackles used on rope ends. Shackles are generally made by die casting process.
 
The hook Of Rigging Hardware
 
A hook is a tool used to hang goods or equipment and is made of steel. The hook is divided into three parts: the hook handle, the hook back and the hook tip.
According to the direction of the upper eye loop of the hook, it is divided into front hook and side hook. The hook tip of the front hook is perpendicular to the plane of the upper eye loop of the hook, and the hook tip of the side hook is on the same plane as the upper eye loop of the hook. . Ordinary cargo hooks mostly use side hooks that have turned bad.
 
Precautions for the use of the hook: When using the hook, keep the force on the central part of the back of the hook to avoid breaking the hook; the strength of the hook is less than that of the shackle of the same diameter. When hanging heavy objects with heavier weight, use it instead. Shackle to avoid straightening and breaking the hook. The customized version of the chain hook needs to be manufactured by an experienced cnc operator.
 
The Chain cable Of Rigging Hardware
 
The chain cable is a chain composed of a gearless chain link. It is often used as a rudder chain, a short cargo chain, a jack chain, and an adjustment chain link for a safety cable. It is also used for pulling and lashing. The size of the chain is expressed in terms of the diameter of the chain link, in millimeters (mm). Its weight can be calculated by the weight per meter length.
When using a chain cable, the chain links should be adjusted first to avoid lateral force, and to avoid sudden force, to prevent the chain from breaking. The chain cable should be checked and maintained frequently to maintain good technical condition. The contact part between the chain link and the chain link, the chain link and the shackle is easy to wear and rust. Pay attention to the degree of wear and rust. If it exceeds 1/10 of the original diameter, it cannot be used. Attention should also be paid to check whether the chain is broken for cracks. During the inspection, you should not only check from the appearance, but use a hammer to hit the chain links one by one, and listen to whether the sound is crisp and loud.
 
The fire impact method should be used to eliminate the rust of the chain. The chain links will expand after heating to make the rust crisp, and then the chain links will collide with each other through the impact, which can eliminate the rust more thoroughly and also eliminate the small cracks on the chain links. The chains after rust removal should be oiled for maintenance to prevent rust and reduce ru.
