n the field of lifting and hoisting, the Eye Bolt is one of the most fundamental and critical connecting components, and its importance is self-evident. It is like the "heart" of a lifting system, connecting the carrying equipment and the lifted object, and its safety directly determines the success or failure of the entire operation.

Standard lifting ring/metric lifting ring
·Feature: The threaded rod is at a right angle to the annular body. This is the most common type.
·Force direction: limited to vertical force only!
·Applicable scenarios: vertical lifting, fixed equipment and other situations without lateral force.

Side pull lifting ring
·Feature: There is a noticeable bend or reinforced neck between the annular body and the threaded rod.
·Force direction: capable of withstanding vertical and lateral tensile forces within a maximum range of 90 °. The work load limit (WLL) will decrease with changes in angle, please refer to the product manual.
·Applicable scenarios: In situations where tilting and pulling are required, such as equipment turning over, tensioning cables, etc., the use is more extensive.

Bolt type lifting ring
·Features: Usually composed of a bolt and a rotatable lifting ring, with a bearing in the middle.
·Force direction: It can withstand loads in the 360 ° direction, but attention should also be paid to the influence of lateral forces on its rated load.
·Applicable scenarios: Heavy equipment that requires flexible lifting in multiple directions, such as molds, machine tools, etc.

Nut type lifting ring
·Feature: The rod is threaded and needs to be fixed with a nut on the connected part with a through-hole.
·Applicable scenario: In situations where it is not possible to drill holes on the workpiece, but it can be clamped with nuts.

Common Misunderstandings and Taboos of Lifting Rings ("Minefield" List)

It is strictly prohibited to use standard lifting rings for lateral pulling.
·Overloading is strictly prohibited.
·It is strictly prohibited to put the lifting ring screw into use before it is fully screwed in.
·It is strictly prohibited to modify the lifting ring in any form such as welding, heating, cutting, or hammering.
·It is strictly prohibited to use lifting rings with mismatched or damaged threads.
·It is strictly prohibited to use bolts or washers to compensate for the insufficient thread length.

The safe journey of a lifting ring begins with the furnace in the factory and ends with every standardized operation！
