Side‑Load Swivel Lifting Point Used For Molds, Wind Power, Construction Machinery, And Heavy Equipment Lifting And Transportation.

Our side‑load swivel lifting point is high‑performance threaded lifting hardware purpose‑built for multi‑angle, side‑pull hoisting scenarios, widely adopted for mold handling, heavy equipment lifting and export machinery packaging. Different from ordinary oval‑link swivel hoist rings, this U‑shaped side‑load lifting point is structurally optimized to bear heavy lateral pulling force, delivering far better performance when lifting at sharp inclined angles, which makes it the preferred lifting point for global mold manufacturers.

This lifting point is hot‑forged from premium 35CrMo or 42CrMo alloy steel, followed by full quenching and tempering heat‑treatment to achieve excellent mechanical strength. Every finished piece undergoes 100% magnetic particle non‑destructive crack inspection to eliminate forging flaws, surface cracks and subsurface defects. All production strictly complies with EN 1677‑1 European lifting component standard. The design safety factor reaches 4:1, minimum breaking load equals four times marked WLL. Each production batch passes proof‑load testing at 2.5× working load limit and fatigue cycle test under repeated lifting stress.

The unit integrates heavy‑duty U‑shaped forged lifting link, dual anti‑friction bearing washers, high‑strength 10.9 grade bolt and locking hex nut. The U‑form main link is stamped with "LIFTING‑POINT" marking for product traceability. Thanks to internal bearing washer structure, the lifting link achieves free 360‑degree horizontal swivel and full 180‑degree tilting movement. During lifting operations, the link can freely orient itself to match sling pulling direction and avoid sling twisting and dangerous torsional stress. The supporting lock nut is a critical design feature: after screwing the bolt fully into workpiece threaded hole, operators must tighten the lock nut firmly against the top washer, so as to prevent bolt loosening caused by vibration and rotation during lifting transit. Multiple thread options are supported: metric thread sizes cover M8‑M64, UNC imperial thread versions are available upon special request for North‑American market. Bolt length can be custom‑extended for thick workpiece installation requirements.

For surface treatment, the U‑shaped link and main body adopt high‑visibility orange paint coating, supporting quick visual inspection for cracks, chipping paint and deformation during daily pre‑lift check. The bolt shank is black‑oxide finished for thread wear resistance, while intermediate bearing washers receive zinc‑plated anti‑corrosion treatment.

Typical application scope includes injection molds, die‑cast molds, stamping dies, heavy gear boxes, generator housings, engineering machinery assemblies and large‑size pressure vessels. It works great for in‑plant workshop handling, machine‑tool mounting, container loading and heavy‑rigging service projects. We are capable of supplying full set of supporting documents including mill test reports, NDT inspection records, batch proof‑load test certificates and CE conformity documentation for import customs clearance and local safety audits.

Strict operation rules must be observed for safe usage. Never exceed the stamped Working Load Limit. Make sure the lock nut is fully tightened against washer after installation. Working load must be properly derated when lifting at inclined side‑pull angles. Mount onto flat, clean machined workpiece surface. Shock loading, impact lifting are strictly forbidden. Do not weld, grind, cut or modify any load‑bearing components of this lifting point. Visual inspection shall be completed before every lifting task. Immediately retire the lifting point if you spot cracks, permanent bending, heavy coating damage or rotational jamming. Periodic re‑inspection is strongly recommended for lifting points operating under high‑frequency or corrosive working environments.
