Sling Length Calculator vs RigThis

Sling Length Calculator has been designed to assist you in selecting slings with enough load carrying capacity for your lifting applications. It is your responsibility to assure that the slings you use are appropriate for your application. Factors you must consider include: • Type of hitch/method of rigging • Effect of angle on capacity • Chemically active environment • Protection from sharp edges • The temperature of load and lift environment • Condition of sling - passes all inspection criteria • The end fittings at the load will see the same force as the sling connected to it, and they must also be adequate for their intended use. • The optimal horizontal sling angle is 60 degrees. This is achieved by having a sling length equal to the distance between pick points.
