Web Slings

DO’s

 – Use only properly identified slings
 – When lifting in a choker hitch, the angle of the choke should form naturally and not be forced
 – The lifting device engaged by a soft eye should be smooth and of such a size that it does not stretch or tear the
sewn joint at the throat
 – Carry out the lift in such a way that the load is stable when several slings are needed. Distribute the load evenly
among the slings and in such a way that the slings hang nearly vertical
 – Store slings away from sunlight and other sources of ultraviolet radiation
 – Inspect the sling before each lift. Look for surface chafe, cuts in the webbing, damage to the edges or chemical
 – attack indicated by softening of the material and deterioration of the seams

DO NOT’S

 – Do not use damaged slings
 – Do not use nylon slings in acid conditions
 – Do not use polyester slings in alkaline conditions
 – Do not expose nylon or polyester slings to temperatures above 80° celsius
 – Do not make knots in sling
 – Do not lift with a twisted sling
 – Do not use web slings for loads with sharp edges

 – Sling angle is the angle measured between a horizontal line and the sling leg or body. The angle is very important and can have a dramatic effect on the rated capacity of the sling – when this angle decreases, the load on each leg increases. This principle applies whether in a basket hitch or for multi-legged bridle slings. When possible, the sling angle should be more than 45o. At any sling angle under 30o a spreader beam should be used. To determine the slings reduced rating according to a specific sling angle, multiply the sling rating by the appropriate loss factor.

 – All Hercules SLR slings are marked to show Working Load Limit (WLL) in vertical, choker and basket hitch. All slings have the largest load capacity when used in the basket hitch. Capacity in the vertical hitch is 50% of that in the basket hitch. Capacity in the choker hitch of single leg slings is a maximum of 80% of the vertical rated load.

 – Always measure slings pull to pull when flat. Approximate stretch at rated sling capacity is 10% for nylon and 5% for polyester. Hercules SLR manufactures slings to a tolerance of ±2% for one and two ply sling and ±4% for three and four ply slings. Please specify when ordering if you require matched pairs of slings.
