JERGENS
Frequently asked questions
Common questions about JERGENS from 3G Electric.
What types of hoist rings does JERGENS offer?
JERGENS offers pivot/swivel hoist rings in center-pull and side-pull configurations. These include force-indicating models that show when the ring is overloaded. Capacities range from 1,800 lb to 17,200 lb, with thread sizes from 1/2"-13 to 1 1/2"-6, plus metric sizes like M36-4.00. Materials include nickel-plated steel and black oxide-coated steel. Side-pull rings are designed for angled lifting, while center-pull rings are for vertical lifts.
What are JERGENS ball lock receiver plugs used for?
JERGENS ball lock receiver plugs are components in quick-change tooling systems. They are installed in fixture plates or subplates to accept ball lock shanks, enabling rapid and repeatable positioning of workpieces. The blue anodized aluminum plug (MPN 49232) has a 16 mm outside diameter and 8 mm overall height, with an M4-0.7 thread and an O-ring for sealing. They are used in machining and assembly operations to reduce setup time.
How do JERGENS force-indicating hoist rings work?
JERGENS force-indicating hoist rings have a visual indicator that activates when the ring is subjected to a load exceeding its rated capacity. For example, model 23520LC has a 3/4"-10 thread and a maximum capacity of 7,000 lb. The indicator provides a clear signal of overload, helping to prevent equipment damage or safety incidents. These rings are used in lifting and pulling applications where load monitoring is critical.
What materials and finishes are available for JERGENS ball lock liners?
JERGENS ball lock primary liners, such as model 49708, are made from steel with a black oxide finish. They have a 16 mm shank diameter and 0.75 in overall height. The black oxide coating provides corrosion resistance and reduces friction during insertion. These liners are used in ball lock systems to guide and retain the locking mechanism, ensuring consistent clamping force in workholding fixtures.
Are JERGENS hoist ring bolt kits available separately?
Yes, JERGENS offers replacement bolt kits for their hoist rings. For example, the Lift-Check bolt kit (MPN 23679LC) is compatible with center-pull hoist ring model 23479LC and has an M30 thread size. The kit includes a bolt and is designed to maintain the original load rating and safety factor. Using manufacturer-specified bolt kits ensures proper fit and performance during lifting operations.
What is the maximum capacity of JERGENS side-pull hoist rings?
JERGENS side-pull hoist rings are rated for specific maximum capacities depending on the model. For instance, model 47318-E has a 1 1/2"-6 thread and a maximum capacity of 17,200 lb for side-pulling. Smaller models like 47313-E with a 1/2"-13 thread are rated for 1,800 lb. These ratings apply when the ring is used in side-pull orientation, and derating may apply for angular lifts.
