In the lifting industry, a large number of users are still using traditional DIN580 eyebolts, but this type of eyebolt has significant drawbacks: poor material, simple structure, and importantly, it cannot rotate at any angle, making it unusable in many cases. If we only look at the low price and continue to use this lifting point without stability, it will cause great lifting danger.
According to the connection method, the lifting points of the rotating ring can be divided into threaded connection and fixed connection. The lifting rings connected to the lifted object are rotatable and universal, that is, the rotating screw connected to the lifted object can rotate 360 ° around the lifting ring, while the chain link connected to the lifting hook and other slings can rotate 180 ° around the lifting ring. The threaded ring is commonly referred to as an eyebolt. According to the usage, the rotating eyebolt of the rotating eyebolt can be divided into ordinary universal rotating eyebolt and side pull universal rotating eyebolt. Universal rotating eyebolts can also be divided into several structures, each with its own advantages. There are two types of eyebolts for fixed connection to the suspended object: bolt fixation and welding fixation. Usually, rotating eyebolts are more practical, and common products are welded D-rings and welded hooks
