For slings and elementsexposed to material fatigue due to frictionand load variation the following ratiosmust be met; 5:1 for steel clable slings;4:1 for steel chain slings and 7:1 forpolyester slings. Thus, an element with abreaking load limit of 1000 kg may bestatically loaded with 200 kg (5:1 safetyfactor) and dynamically loaded with 142kg (7:1 safety factor).When a system is flying, the workingload must be lower than the resistance ofeach individual flying point in theenclosure, as well as each box. Hanginghardware should be regularly inspectedand suspect units replaced if in doubt.This is important to avoid injury andabsolutely no risks should be taken in thisrespect. It is highly recommended thatyou implement an inspection andmaintenance program on flying elements,including reports to be filled out by thepersonnel that will carry out theinspections.
