GENERAL NOTES:
(a) The rated loads are based on stuffer weave construction webbing with a minimum certified tensile strength of 9,800 pounds per inch of width of the webbing.
(b) Rated loads for Types III and IV slings apply to both tapered and nontapered eye constructions. Rated loads for Type V slings are based on nontapered webbing.
(c) For Type VI slings, consult the manufacturer for rated loads.
(d) For choker hitch, the angle of choke is 120 deg or greater.

GENERAL NOTES:
(a) Roundslings are identified by the vertical rated load shown on the sling identification. The size numbers in the first column have been adopted by the Web Sling & Tie Down Association to describe certain polyester roundslings. They are included for references only. Other polyester roundslings may have different vertical rated loads.
(b) Color guidelines for polyester roundsling covers are widely used to indicate the vertical rated load of roundslings; however, this is not followed by some manufacturers. Always select and use roundslings by the rated load as shown on the sling identification; never by color.
(c) For choker hitch, the angle of choke is 120 deg or greater.

Fig. 5 Hitch Types for Synthetic Rope Slings
The symbols below represent load or support surfaces in contact with the rope sling. The contact surface diameter divided by the rope diameter is designated D/d ratio as described in Fig. 6. Tables 18, 19, and 20 are based on the D/d ratios indicated below.


illustration Represents a contact surface which has a diameter of curvature at least double the diameter of the rope from which the sling is made.
illustration Represents a contact surface which has a diameter of curvature at least 8 times the diameter of the rope.
illustration Represents a load in choker hitch and illustrates the rotary force on the load and/or the slippage of the rope in contact with the load. Diameter of curvature of load surface is at least double the diameter of the rope.
General Note: Legs 5 deg or less from vertical may be considered vertical. For slings more than 5 deg vertical, the actual angle shall be used.

Fig 7 Synthetic Webbing Slings-Type I

Sling made with a triangle fitting on one end and a slotted triangle choker fitting on the other end. It can be used in a vertical, basket, or choker hitch.

Type I

Fig 7 Synthetic Webbing Slings-Type II

Sling made with a triangle fitting on both ends. It can be used in a vertical or basket hitch only.

Type II

Fig 7 Synthetic Webbing Slings-Type III

Sling made with flat loop eye on each end with loop eye opening on same plane as sling body. This type of sling is sometimes called a flat eye-and-eye, eye-and-eye, or double-eye sling.

Type III

Fig 7 Synthetic Webbing Slings-Type IV

Sling made with both loop eyes formed as in Type III, except that the loop eyes are turned to form a loop eye which is at a right angle to the plane of the sling body. This type of sling is commonly referred to as a twisted-eye sling.

Type IV

Fig 7 Synthetic Webbing Slings-Type V

Endless sling, sometimes referred to as a grommet. It is a continuous loop formed by joining the ends of the webbing together.

Type V

Fig 7 Synthetic Webbing Slings-Type VI

Return-eye (reversed-eye) sling is formed by using multiple widths of webbing held edge-to-edge. A wear pad is attached on one or both sides of the sling body and on one or both sides of the loop eyes to form a loop eye at each end which is at a right angle to the plane of the sling body.
