About this product
Material: 42CrMoA Hardness: HRC38-42
Executive Standard: EN ISO 12100:2010; EN ISO 3266:2010/A1:2015; EN 1677-4:2000/A1:2008
Unlike normal eye bolts, these Hoist Rings will not yield to heavy side loads within their rated capacity and can pivot 180° and swivel 360° to compensate for pitch, roll and sway when lifting heavy, unbalanced loads.
- Grade 80
- CE CERTIFICATE
- 4 Times coefficient of safety
- Forge alloy steel

Inspection Procedure
- Overall dimensions inspection according to acceptance criteria. No crack and defect, the marks of specification , supporting capacity and material on the surface should be clear.
- Test with thread ring gauge. Precision grade 6g(0.21OZ)
- Thread axis vertical to bearing surface, rotating the gauge to the screw root, if it's of seamless joint with bearing surface, then vertical qualified.
- Qualified hoist ring must offer the certificate or detailed examining report in written form, and keep in the archives.

All are 4 times to the safety coefficient at all the lifting directions.
- Thread holes are deep enough to ensure that the bolt is fully screwed in
- bolt firmly fixed contact surface mount(with manual rotation, do not allow using tools to tighten)
- Equipment materials can withstand tension, will not deform.
