The YOKE Yellow Point (YP) swivel eye‑bolt product series delivers reliable solutions for industrial lifting and mold‑making applications, thanks to its outstanding safety performance and versatile multi‑directional capability. The series comprises four core models—8‑271, 8‑211, 8‑231, and 8‑291K—all manufactured from forged alloy steel that has undergone quenching and tempering, ensuring exceptional structural strength and durability.
The following are the key features and introductions of each model:
8-271 Universal Swivel Lifting Ring : The most distinctive feature of this model is its unique ball-bearing design, which not only supports 360° horizontal rotation but also enables a wide 230° tilting lift—far exceeding the conventional 180° tilt range. With a design safety factor of 4, it is particularly well-suited for lifting operations that require multi‑angle positioning and complex load‑bearing conditions.
8-211 Lateral Rotating Hoist Ring : Specifically designed for high-angle lateral pull and overturning applications, it features 360° rotation and 180° pivot‑axis rotation. Its most significant technical highlight is its support for 100% vertical flip However, the maximum working angle is limited to 90 degrees, making it ideally suited for lateral flipping and positioning operations in mold applications.
8-231 Lifting Rotary Eye Bolt As a versatile swivel lifting ring, it offers 360° rotation and 180° flipping, enabling lifting from any direction. Installation is simple and quick—simply machine a threaded hole in the workpiece to complete assembly—making it ideal for general-purpose handling of machinery and equipment.
8-291K Eye-Type Swivel Hoist Ring with Stop Plate This model builds on the eye‑shaped lifting ring by incorporating a locking tab, enabling 360° rotation and 180° flipping. The locking tab effectively prevents the ring from unintentional rotation under vibration or impact, enhancing the stability of the connection point—making it especially well suited for mold‑handling applications that require frequent repositioning and mold changes.
In terms of safety and quality, the entire product line has undergone 100% magnetic particle inspection , ensuring there are no surface cracks. Each product is subjected to a proof load equal to 2.5 times its working limit load and has successfully passed a fatigue‑limit test consisting of 20,000 cycles at 1.5 times the working limit load, fully meeting or exceeding the requirements of the ASME B30.26 international standard. These rigorous tests and certifications have enabled the YOKE YP series to be widely employed in mold handling, wind‑energy installation, port terminals, and the assembly and maintenance of various heavy‑duty machines.
