The red rotating hook is positioned with "high strength, high flexibility, and high safety" as its core, and is made of high-quality alloy steel. The standard model uses G80 grade high-strength steel, which can be upgraded to G100 grade according to heavy load requirements. Through precision machining using forging and heat treatment processes, the hook has a tensile strength of ≥ 1000MPa (minimum tensile strength of G80 grade ≥ 800N/mm ²) and can easily handle rated loads ranging from 1 ton to over 50 tons, providing solid support for heavy lifting operations. ​
The 360 ° free rotation structure is its iconic design, which achieves seamless rotation through built-in rotating bearings, completely solving the problem of load shaking caused by rope twisting during the lifting process. It keeps the goods stable throughout the lifting, translation, and landing process, greatly reducing the risk of equipment loss caused by angle deviation. The opening size of the hook covers the standard range of 20mm-80mm, with an overall length of 150mm-500mm+. Non standard sizes can be customized according to special working conditions to meet diverse lifting needs.

FAQ

Q1: What is the maximum load capacity of the crane swivel hook?

A1: The rated load capacity ranges from 1 ton to 50+ tons, depending on the model. Each hook is clearly marked with its maximum load to prevent overloading. For custom heavy-duty requirements, G100 grade alloy steel options are available.


Q2: Can the hook rotate 360 degrees continuously?

A2: Yes, the hook is designed for 360° free rotation, which helps eliminate rope twist and allows for smooth positioning in complex scenarios such as crane operations or tight-space lifting.


Q3: Is the safety latch mandatory, and how does it work?

A3: Yes, the safety latch is a standard feature on all models. It automatically rebounds to lock the hook mouth after loading, preventing accidental detachment of loads during lifting and movement.


Q4: What materials are used in the construction, and is it corrosion-resistant?

A4: The hook is made from high-strength G80 alloy steel, and its surface is coated with red anti-corrosion paint. This protective coating resists moisture, dust, and minor chemical corrosion, making it ideal for outdoor and industrial environments.
