Lifting Ring

Wholesale high quality lifting ring from BaiYi factory.The core design of lifting rings is to safely transmit vertical lifting force to the lifted equipment or structure through their threaded parts.According to the different directions of force, lifting rings are mainly divided into two types: vertical lifting rings and inclined lifting rings. Proper selection and use of lifting rings are crucial for preventing lifting accidents.

Specification：

When selecting the lifting ring, it is necessary to confirm the following key parameters engraved on the lifting ring。

1 Thread specifications: nominal diameter (such as M10, M20, 1/2 "-13, 3/4" -10, etc.) and pitch. It must be perfectly matched with the threaded holes on the work piece.

2 Safe working load: The maximum load allowed under specified conditions, usually measured in tons or kilonewtons. SWL is the most important parameter of the lifting ring.

3 Material grades: Common ones include carbon steel (such as Grade 4.8, 8.8), alloy steel (such as Grade G80/8), and stainless steel (such as 304, 316). The grade determines its strength and corrosion resistance.

4 Type of lifting ring: Vertical force bearing type (with load-bearing plane on the shoulder) or diagonal tension type (can withstand force from multiple angles, commonly 45 °).

Features

1 High strength design: Made of high-quality alloy steel forging and heat-treated, it has extremely high tensile strength and durability.

2 Standardization: Standardization of size and load capacity facilitates selection, procurement, and interchangeability.

3 Easy to install: Simply screw into the pre made threaded hole to use.

4 Diverse types: In addition to the standard type, there are also various variants such as rotating lifting rings (360 ° rotation), adjustable lifting rings, welded lifting rings, and plate lifting rings to adapt to different application scenarios.

FAQ

Q1: Can vertical lifting rings and diagonal lifting rings be mixed?

A: Absolutely not allowed. Vertical lifting rings can only withstand axial tension, and lateral forces can cause them to bend or even break, which is extremely dangerous. The cable-stayed lifting ring is specially designed and reinforced to safely withstand forces within a certain angle.

Q2: Can the lifting ring be reused?

A: Sure, but the prerequisite is that it has undergone strict inspection to ensure that there is no damage or deformation, and that it has not exceeded its design working limit.

Q3: How to calculate the required size of SWL lifting ring?

A: SWL should be greater than or equal to the maximum total weight of the lifted object。

Q4: Does the lifting ring need to lubricate the threads?

A: It is usually recommended to apply a small amount of lubricating oil (such as butter) on the threads to facilitate installation and ensure that the specified pre tightening force is achieved, while also preventing thread corrosion and biting.
