Every Lift Uses 1 of 3 Basic Hitches
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.

Effect of Angle Increases
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.

Example:
Assume sling capacity is 2 000 lbs in vertical hitch and 4 000 lbs. in a 90o basket hitch
If the sling angle is 50o, then the loss factor is 0.766
Multiply 4 000 lbs. x 0.766 = 3 100 lbs
3,100 lbs. is the rated capacity in the basket hitch at a sling angle of 50o

Design factor
All working load limits are based on a factor of 5:1

Length of Web Sling
Always measure slings pull to pull when flat as shown. 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 slings and ±4% for three and four ply slings. Please specify when ordering if you require matched pairs of slings.

Sling Capacity Decreases as the
Angle from Horizontal Decreases

A sling capable of lifting 1 000 lbs in a 90 vertical basket hitch can only lift 866 lbs at a 60 angle, 707 lbs at a 45 angle and 500 lbs at a 30angle.

for Use AND Maintenance of 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

OS&H mandates that:

“ Each day before being used, the sling and all fastenings and attachments shall be inspected for damage or defects by a competent person designated by the employer. Additional inspections shall be performed during sling
use, where service conditions warrant.”

The rated loads are based on stuffer weave construction webbing with a minimum certified tensile strength of 9 800 lbs per inch of width of webbing. Rated loads for types 3 and 4 slings apply to both tapered and non-tapered eye constructions. Rated loads for type 5 slings are based on non-tapered webbing. For choker hitch, the angle of choke shall be 120° or greater. Design Factor 5 : 1. For type 5 and 6 slings, consult Hercules SLR for rated loads of choker and basket applications. ( As per ASME B30.9-2003 slings )
