Actek 2"-4-1/2 x 3.2" UNC Swivel Hoist Ring - 30000 lbs WLL

Actek Safety Swivel Hoist Rings – UNC Thread Series

Actek Safety Swivel Hoist Rings are high-strength, American-made lifting points engineered for safe, reliable overhead lifting. Built from certified alloy steel and proof-tested to 200% of rated capacity, these hoist rings deliver unmatched performance and traceable safety. Each unit swivels a full 360° and pivots 180°, ensuring proper load alignment and preventing side-loading stress.

Key Features

• Made in the USA — manufactured by Actek Manufacturing & Engineering, an industry leader in precision lifting hardware.
• 200% proof-load tested and serialized — each hoist ring is individually tested and marked for complete traceability.
• 360° swivel / 180° pivot — provides smooth load rotation and alignment without inducing bolt torque.
• Alloy steel construction — heat-treated, magnetic particle inspected, and certified for maximum strength and fatigue resistance.
• 5:1 design factor — meets or exceeds ASME B30.26 and CE requirements for safety and performance.
• Rated 100% from 0°–90° — maintains full working load limit even during angular lifts.
• Fatigue tested — proven through 20,000 cycles at 1½× the rated load.
• Durable finish — standard black oxide coating; optional cadmium, zinc, or electroless nickel plating available.
• Readily available — most popular sizes are in stock for quick shipment at competitive prices.

Capacity & Size Range

Available in standard UNC thread sizes from 1/4"-20 through 2-1/2"-8, with working load limits ranging from 600 lbs up to 50,000 lbs. Larger sizes—rated up to 250,000 lbs—are available by special order.

Typical Applications

• Machinery lifting and rigging points
• Tooling, die, and mold handling
• Construction and fabrication work
• Heavy equipment assembly and transport

Safety & Installation Guidelines

• Never exceed the rated load capacity. The 5:1 safety factor is designed to protect against accidental misuse and dynamic forces.
• Always tighten to the recommended torque values and check periodically—bolts can loosen over time under vibration or repeated use.
• Ensure full material strength. The parent material should have a tensile strength of at least 80,000 PSI. For softer materials, consider a through-hole mount with a backing nut and washer.
• Avoid shock loading. Always lift gradually; sudden or impact loads can cause serious damage and require reinspection before reuse.
• Verify free movement. Make sure the hoist ring can pivot and rotate freely in all directions before each lift.
• Understand load distribution. Load on each hoist ring may exceed total weight divided by the number of rings—especially at shallow lifting angles or uneven loads.

Note: Regular inspection and proper installation are critical to safe operation. If shock loading or deformation is suspected, discontinue use and perform magnetic particle (Magnaflux) testing before returning the hoist ring to service.
