Alloy Chain Slings (Grade 100, 80 & 120)

Holloway Manufactured Chain Slings for Heavy Lifting

Holloway Houston Inc. (HHI) is a premier manufacturer of high-performance chain slings, engineered to meet the most demanding lifting requirements in the world’s toughest industries. Operating out of the nation's largest single-location sling shop and testing facility in Houston, Texas, we don't just sell equipment—we build it.

Every Holloway chain sling is fabricated in-house using Grade 100 alloy steel, providing a 25% higher strength-to-weight ratio than traditional Grade 80. Our inventory supports chain diameters from 1/4" to 1-1/2", available in single, double, triple, and quad-leg configurations.

Safety is our non-negotiable standard. Every sling we manufacture is proof-tested to 2x its vertical working load limit (WLL) in our NRTL-accredited laboratory before it leaves our facility. Whether you need a standard assembly or a custom-engineered lifting solution, our slings are fully compliant with OSHA 1910.184, ASME B30.9, and NACM standards .

Chain Sling Configurations

Choosing the right configuration is essential for load stability and rigger safety. Holloway provides the following standard builds:

Single-Leg Chain Slings

The single-leg chain sling is the most common tool for direct vertical lifts. Ideal for loads with a single, centered attachment point, these slings are lightweight and easy to handle. They are frequently used in construction for pipe handling and small machinery moves.

Double-Leg Chain Slings

Featuring two legs attached to a single master link, these 2 leg chain slings provide the lateral stability required for balanced, symmetrical loads. By distributing weight across two points, they allow for higher capacities and safer control during transit.

Triple-Leg and Quad-Leg Chain Slings

Designed for heavy, irregular, or asymmetrical loads, our 3-leg and 4-leg (bridle) slings provide maximum stability. These configurations are the "workhorses" of the oilfield and heavy manufacturing sectors, capable of lifting massive modules and large-scale equipment.

Adjustable Chain Slings

For loads with uneven centers of gravity, our adjustable chain slings feature integrated shortening clutches. This allows the rigger to adjust the reach of each leg independently, ensuring the load remains level even when attachment points are at different heights.

Chain Sling Capacity Chart — Grade 100

Below are the rated capacities for our most common Grade 100 chain sizes.

Note: Capacities shown are at rated sling angles. Reduce rated capacity by 20% for choker hitch applications. Never use chain slings at angles less than 30 degrees from horizontal.

Grade 80 vs Grade 100 Chain Slings

While both grades are approved by ASME B30.9 for overhead lifting, Holloway has moved to Grade 100 as our manufacturing standard. Grade 100 chain offers a significant ergonomic advantage: it provides 25% more lifting capacity for the same chain diameter as Grade 80. This means your rigging team can use a lighter, smaller chain to do the same job, reducing fatigue and the risk of onsite injuries. Grade 80 remains a reliable choice for specific legacy applications, but Grade 100 is the industry-leading choice for modern safety and efficiency.

Industries and Applications

Chain slings are the preferred rigging choice when environmental factors would destroy synthetic or wire rope alternatives. They excel in:

• Steel Erection: Handling abrasive beams and plates.
• Foundries: Operating in high-heat environments where synthetic webbing would melt.
• Marine & Shipbuilding: Resisting the rigors of heavy dockside and offshore lifts.
• Oil & Gas: Surviving the rough handling of drill site operations.
