Temperature Considerations for Sling Use
Slings are critical for keeping loads on overhead cranes attached, steady and balanced. But when you operate your cranes in high temperatures, you must be careful to ensure that your equipment remains in good working order.
Certain temperatures are simply too hot for equipment to remain stable and intact—and care should be taken to replace rigging equipment that has been exposed extreme temperatures.
Inspections: Safe operating temperatures
Employers must permanently remove an alloy steel-chain slings from service if it is heated above 1000 degrees F. When exposed to service temperatures in excess of 600 degrees F, employers must reduce the maximum working-load limits permitted by the chain manufacturer in accordance with the chain or sling manufacturer's recommendations.
