DO NOT EXCEED RATED CAPACITY
Warning: Sling can fail if damaged, misused or overloaded. Inspect before use. Damaged sling shall not be used. Use only if trained. Do not exceed rated capacity. Protect sling from being cut by load edges, corners, protrusions and abrasive surfaces. Avoid exposure to acid, alkali and temperatures over 300°F. DEATH or INJURY can occur from improper use or maintenance.
Slingmax® Check-Fast® Inspection System
Also known as the
Fast® System
Patent #7,661,737 Foreign Patents Pending
The Check-Fast® System is designed to improve job-site safety. The
Fast® Tag and External Warning Indicator (EWI) on a round sling product provides for a pass/fail inspection of the internal load bearing core yarn. Damage to the core yarn from ultraviolet (UV) light degradation, fiber on fiber abrasion, fatigue, and severe overload can be detected. If the sling is mistakenly overloaded beyond rated capacity, the EWI is designed to disappear before the sling fails. The sling inspector now has a GO/NO-GO inspection device rather than relying on a subjective hand-over-hand inspection to make an educated guess if the load bearing core yarns are in good condition. This safety system is available for High Performance K-Spec® Fiber Round Slings or polyester round slings fabricated by authorized Slingmax® Dealers.
