Use Case
This structure is used for heavy rigging training, occupational safety (HSE) presentations, forging vs. machining comparisons, and angular load capacity reduction analysis.
Working Load Limit (WLL)
Explains the maximum load the eye bolt can carry in a straight pull (0°) versus the drastic capacity reduction during 45° angular lifts.
Forging Process (Grain Flow)
Demonstrates how forging aligns the metal grain flow with the part's contour, making it far superior to machined counterparts that are prone to snapping.
Assembly & Flush Seating
Highlights the critical importance of the bolt's shoulder making full contact with the mating surface to prevent dangerous bending moments.

Lifting Eye Bolt
Rigging and Lifting Element
A ringed bolt calibrated to international norms that provides a secure attachment point for crane hooks to lift heavy machinery.
In lifting equipment, machining from solid billet is strictly prohibited! If this ring were machined (CNC), the metal grain flow would be severed, leading to catastrophic failure under load. Drop forging bends the grains without breaking them, ensuring maximum toughness. Furthermore, if the ring is pulled at a 45-degree angle, its Working Load Limit (WLL) drops by up to 70%. Occupational safety standards mandate that the shoulder must seat perfectly flush against the machine surface to prevent bending stress.
