The Extreema INFERNO® IF3 Heat Resistant Endless Round Sling (7,000 lbs WLL) is a specialty roundsling engineered for lifting operations in high-temperature environments. Where standard polyester and nylon slings degrade rapidly above 194°F, the INFERNO maintains its rated capacity at temperatures that would destroy conventional synthetic slings — making it essential for foundry, forge, and heat-treating operations.
Key Features
- 7,000 lbs working load limit
- Heat-resistant fiber construction maintains strength at elevated temperatures
- Far exceeds the temperature limits of standard polyester (194°F) and nylon (180°F) slings
- Endless roundsling configuration for uniform load distribution
- Color-coded for quick capacity identification
Common Applications
- Foundry and forge operations — handling hot castings and forgings
- Heat-treating facility material handling
- Steel mill operations near furnaces and hot processes
- Any lifting application where ambient or load temperatures exceed standard sling limits
Why INFERNO®?
Standard synthetic slings lose strength rapidly above their rated temperature limits. The INFERNO is purpose-built for heat — maintaining its rated capacity in environments where standard slings would melt, weaken, or fail. Essential protection for crews working near hot processes.

Governing Standards
- ASME B30.9 — slings (web, round, wire rope, chain) inspection and use
- ASME B30.26 — rigging hardware (shackles, eye bolts, links, turnbuckles)
- ASME B30.10 — hooks
- OSHA 1910.184 and 1926.251 — general industry and construction sling safety

Inspection & Safety
Before every use: visual check for cracks, corrosion, distortion, wear, and illegible markings. Annually (minimum): documented periodic inspection by a trained inspector. Remove from service at first sign of damage. Never repair rigging hardware by welding, heating, or bending.
WARNING: Improper use of rigging can cause death or serious injury. Never exceed the rated Working Load Limit. Apply derating for side-loading, elevated temperature, or chemical exposure. Final application decisions must be made by a Qualified Person per OSHA 1926.32(m).
