Single part body mechanically spliced wire rope slings.

Eyes are typically formed using a flemish eye splice. The ends are secured by pressing a metal sleeve over the ends of the strands of the splice. Pull follows a direct line along the center of the rope and eye. Single part body mechanical splice slings have a higher rated capacity than hand-spliced slings.

Flemish Eye Splice

In the standard flemish eye mechanical splice, wire rope is separated into two parts: three adjacent strands to one part and three adjacent strands along with the core to the other part. The two parts are then re-laid back in opposite directions to form an eye and ends are secured with a pressed metal sleeve.

Swaging provides a good grip.

This photo shows a cutaway of a metal sleeve that’s been swaged onto a splice. Notice how metal flows into the valleys between strands to positively prevent ends from unlaying when the sling is used within its rated capacity.

Socket Assemblies

Spelter Socket.

Molten zinc is the standard socketing material, however, an epoxy socketing material can be specified. Both have the same Rated Capacity. Steel forgings are used on rope sizes 1/2” through 1 – 1/2” and cast steel fittings are used for larger sizes. Rope sizes larger than 4” are available on special order. The assembly lengths are measured from the centerline point of the pin for open sockets and the bearing point for closed sockets.

110 Spelter Socket

Swaged Socket.

In mechanically swaged fittings, high pressure presses and precision dies cause the metal of the socket to flow around the wires and strands to result in the ultimate compactness and strength with minimum weight. The material is weldless, drop -forged steel. Normally, only regular lay rope is used in the swaged sockets. The swaged assemblies are inter- changeable with poured sockets up through 2” rope diameters. Assembly length is measured from the centerline of pins for both open and closed swaged sockets

How To Order

All slings are fabricated to customer specifications. Therefore, your purchase order should contain the following specific details.

  1. Sling model number
  2. Sling length as indicated on schematics alongside tables
  3. Component rope diameter
  4. Eye treatments
  5. Any special fittings, such as sliding choker hooks
  6. Any other special requirements

Bridles will be fabricated with
oblong alloy steel links unless
otherwise specified

To minimize the chance for error in
transmitting orders, use the model
numbers given for each sling type,
followed by the letter codes in the
illustrations for indicating eye or
end treatments.

For example, a type 110-ST-TH-HT choker would be a single-part, hand- spliced sling with a slip-through thimble (ST) in one eye, a sliding hook (TH) and a heavy-duty thimble (HT) in the other eye.

Standard sling eye designations are as indicated on the drawings at left for both mechanically and hand- spliced slings. Other combinations or other types of hooks or fittings can be specified.

The sling body length is the length of wire rope between splices, sleeves, or fittings. The standard minimum body length is ten times the sling body diameter. The standard minimum body length for multi-part slings between splices is equal to forty times the component rope diameter.

Metal tags are available upon request.

Eye treatments

Sling eyes may be protected by thimbles, rubberized coating, wire serving, or other special treatments which you may specify. Rubberized coating is standard where indicated on schematics accompanying tables for certain multi-part slings.

Otherwise, rubberized coating must be specified as an extra.

If serving is desired on splices of single-part, hand-spliced slings larger than 1-1/2” rope diameter, it must be specified and is an extra.

Four types of thimbles are offered:

Heavy-duty thimbles (HT) are placed in eyes when formed. Slip-thru (ST) thimbles, which may pass through one another, are placed in eyes during forming, and held in place by bend- down tabs. Slip-on thimbles are of two types: crescent (CT) and formed (OT). Both are inserted after eyes are formed. Crescent type thimbles (CT) are held in place by bend-down tabs.

WARNINGS

In the real world, accidents do happen, and that’s why you need to take special precautions. Before installing wire rope in your applications, always read and follow the warning label attached to each product.
