How to Measure and Specify Wire Rope Slings The standard eye/eye wire rope sling is illustrated below. Two dimensions are required to specify this wire rope sling:

1. Wire rope diameter.

2. Sling length. Wire Rope Slings Wire The length of a wire rope sling is measured from the bearing surface of one eye to the to bearing surface of the opposite eye, as shown in the following diagram.

The size of standard eyes for wire rope slings are shown in the following table. These dimensions should be considered approximate as they will vary slightly depending on the splicing technique used by the individual who actually fabricates the sling.

The drawback of this type of splice which affect the overall strength of the sling. is that the lifting capacity of the sling depends These other factors include: entirely upon the integrity of the pressed or swaged metal sleeve. Return loop splices are • Efficiency of the eye splice or end termination used almost exclusively on small diameter attachment. aircraft cable, in sizes below 3/8 inch diameter. • Number of parts of rope in the sling (applies to The Flemish eye splice is fabricated by braided slings only). opening or unlaying the rope body into two • Type of hitch with which the sling is attached parts, one having three strands and the other to the load (straight pull, choker hitch, basket having the remaining three strands and the hitch, etc.).

• Diameter around which the body of the sling is bent (D/d ratio).

• Diameter of the pin or hook that attaches the sling to the lifting or pulling apparatus.

The wire rope sling capacity tables presented later in this section take these and other factors—including design factor—into account when presenting wire rope sling capacity.

Wire Rope Sling Splices There are three basic splice types: hand tucked, return loop mechanical, and Flemish eye mechanical.

This is because sling will have a capacity of approximately 74% each leg of the sling carries half of the load. of its straight pull rating. Sling capacity is unaffected with a straight D/d Ratio pull or attachment. D/d ratio is the ratio of the diameter of an

This ratio has an effect on the rated the opposite sling eye, thus “choking” the sling capacity of the sling when the body of a sling is around the load. The load is then suspended or bent around an object. Tests have shown that pulled from the free sling eye. The choker hitch whenever wire rope is bent around a diameter, reduces the capacity of the sling. The contact the strength of the rope is decreased due to of the sling body with the choking eye causes bending stress in the wires that make up the a reduction in sling efficiency at the point of rope. Minimal strength reduction occurs with contact.

Single-part Flemish eye mechanical splice A Grommet is a unique type of wire rope sling slings are fabricated with a single length which forms a continuous loop. There are two of wire rope, typically EIPS grade, and with basic types of grommets: cable laid and strand laid. Flemish mechanical splices.

Multi-part slings achieve capacities spliced and care must be taken to ensure that greater than that of single-part slings of the same the splice does not come into contact with the diameter wire rope or cable. And, in the case of load or the lifting or pulling attachment. Since 9-part slings, the capacity increase is significant. the grommet is made up of many smaller wire Multi-part slings are significantly more flexible ropes or cables, the grommet can bend around than single-part slings of like capacity. Because a smaller diameters without taking a permanent multi-part sling is made up of many smaller wire set or kink.
