Products Description
Lifting Ring Expansion Screws are multifunctional fasteners that combine an expansion anchor structure with a circular lifting ring, integrating two core functions: permanent mechanical expansion anchoring in concrete and masonry substrates, and reliable load lifting and hoisting via the integral lifting ring at the top. Once installed, the expansion sleeve expands tightly within the pre-drilled hole, providing high pull-out resistance; meanwhile, the closed-end lifting eye serves as a stable attachment point for slings, ropes, and lifting tools, functioning as a fixed lifting anchor for equipment hoisting, temporary suspension, and the positioning of heavy components.

Working Principle
- Drill hole with matched diameter and depth on solid wall base, clean dust and residues thoroughly;
- Insert the whole lifting ring expansion screw assembly into the drilled hole completely;
- Tighten the nut to pull the tapered cone toward the inner side, squeeze the slotted expansion sleeve to expand outward and closely lock with hole wall, forming firm mechanical friction interlock;
- After full expansion locking, the exposed integrated circular ring becomes reliable load-bearing point for hoisting, hanging and fixing.
