Q: What is the difference between Lifting Pin Anchors and Eye Anchors? How to choose between them?
A: 1)Structural differences: Lifting Pin Anchors connect to external lifting devices via their head, while Eye Anchors allow direct hooking of slings. 2)Applicable scenarios: Lifting Pin Anchors: Suitable for lifting requiring high precision, concealment, or frequent disassembly (e.g., formwork support, equipment installation). Eye Anchors: Ideal for simple hooking needs or one-time lifting (e.g., prefabricated wall panels). Selection advice: Base your choice on lifting frequency, force direction (whether multi-angle adjustment is needed), and aesthetic requirements.
Q: Can Lifting Pin Anchors withstand lateral tension?
A: Limitations: Lifting Pin Anchors have weak resistance to lateral forces, as they are designed to primarily bear axial tension. Solutions: If lateral forces exist, add shear-resistant reinforcement bars or switch to lateral force-resistant structures like Eye Anchors.
Q: During lifting, if the head of a lifting anchor fractures, what are the possible causes?
A: Common causes: 1)Overloading or insufficient safety factor. 2)Material defects (e.g., internal cracks, corrosion). 3)Size mismatch between the lifting device and the anchor head, causing stress concentration.
