The Check-Fast™ System
is an independent sacrificial element in
the roundsling and is not a part of the
actual load bearing structure of the sling.
If the Check-Fast™ System
indicates internal damage is does so without
further weakening of the bearing core.
|
Fast® Tag and External Warning Indicator (EWI) on a roundsling product provides for a pass/fail inspection of the internal load bearing core yarn. Damage to the core yarn from 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 inspector no longer has to feel and squeeze around the entire sling to guess if the core has been severely overloaded. This safety system is available for polyester or High Performance K-Spec® Fiber Roundslings fabricated by authorized SLINGMAX® Dealers.
