American ADB (American Drill Bushing) lifting rings enjoy a strong reputation in the industrial lifting sector, renowned for their safety, reliability, and superior design. ADB offers a wide range of lifting ring series to meet diverse lifting requirements across various applications. Below, I’ll introduce some of the key series and their distinctive features. To help you quickly grasp the main ADB lifting ring product lines:

The content published on the U.S. ADB suspension ring product introduction website typically includes information such as product specifications, features, and application areas. Below are some specific examples:

Product Specifications:

Model 23600: The material is alloy steel, the mounting method is screw-in, the working load limit is 75,000 lbf, the thread size is 3"-4", the pivot angle is 180°, the rotation angle is 360°, the minimum installation torque is 4,300 ft-lb, the surface finish is black oxide, the minimum operating temperature is -20°F, and the maximum operating temperature is 400°F.

Model 23200: Also made of alloy steel, it features a screw-in installation, a working load limit of 30,000 pounds, a thread size of 2"-4-1/2, a pivot angle of 180°, and a rotation angle of 360°. The minimum installation torque is 1,100 ft-lbs, with a black oxide finish, and it operates within a temperature range of -20°F to 400°F.

Model 34040S: Rated load: 5,000 lbs; Size A: 3 inches; Size B: 2-5/8 inches; Size C: 1-1/2 inches; Size D: 1/2 inch; Size E: 3-7/8 inches; Size F: 1-1/8 inches; Size G: 1/2 inch (2 PLCS); installation torque: 20–25 ft-lbs; weight approximately 2.06 lbs (including screws).

Product Features:

High Security: The design safety factor is a minimum of 5:1, as in the ADB® Heavy Duty® Hoist Ring 33427, which is made from forged alloy steel with a minimum tensile strength of 180,000 psi and undergoes 100% magnetic particle inspection.

Flexible range of motion: Most eye bolts can rotate 360° and swivel 180°; for example, the ADB stainless steel safety‑grade swivel eye bolt maintains this range of motion even under load, helping to prevent chains, ropes, and slings from twisting or bunching during lifting operations.

High-quality surface treatment: Common surface treatments include black oxide coating to resist corrosion, with a variety of plating options available, such as cadmium, titanium‑cadmium, and nickel.

Product application areas: ADB lifting rings are widely used in industries such as aerospace, defense, manufacturing, stamping and injection molding, power generation (nuclear, hydro, wind), construction, mining, concrete, and precast.

Brand Advantages: ADB is the pioneer and industry-leading manufacturer of lifting eyebolts and safety lifting equipment. Its products are certified under the ISO 9001:2008 quality management system, ensuring that all processes are controlled and implemented in accordance with established procedures, and that 100% of its products are manufactured and assembled in the United States.
