There are many different types and sizes of hand swaging tools.

Bench-Mounted vs. Hand-Type Swaging Tools

Bench-mounted swaging tools and hand-type swaging tools serve the same purpose of permanently connecting ferrules to cables using compression. However, they differ in their design and how they are operated:

Bench Type Swaging Tool

Hand Type Swaging Tool

Bench-Mounted Swaging Tools:	Hand-Type Swaging Tools:
Fixed in place on a workbench or sturdy surface Typically larger and more heavy-duty compared to hand swaging tools Often used for high-volume or industrial applications where precision and consistency are crucial Operated by pulling a lever to apply force to compress the swage fittings onto the cable	Portable and operated by hand Generally smaller and more lightweight compared to bench-mounted tools Suitable for smaller-scale projects or fieldwork where mobility is important Requires more manual effort to compress the swage fittings onto the cable Some tools can swage multiple sizes of cable ferrules (called a multi-cavity) while others can can only swage one size of ferrule (called a single cavity).

Bench-Mounted Swaging Tools:

Typically larger and more heavy-duty compared to hand swaging tools

Portable and operated by hand
Generally smaller and more lightweight compared to bench-mounted tools
Suitable for smaller-scale projects or fieldwork where mobility is important
Requires more manual effort to compress the swage fittings onto the cable
Some tools can swage multiple sizes of cable ferrules (called a multi-cavity) while others can can only swage one size of ferrule (called a single cavity).

Advantage Sales carries a wide selection of Hand Swaging Tools. Many are fitted with multiple cavities to cover a range of cable sizes. Download the Advantage Sales Catalog page on Swage Fittings and Hand Swaging Tools(opens in a new tab) below.

Cable Sleeves

Shaped like an hourglass, Cable Sleeves are generally used to make an eye by feeding the cable end through one side of the sleeve and then back through the other side. The Sleeve is then crimped with a hand swaging tool.

How to Apply Cable Sleeves

These instructions are for hand swaging small cable assemblies in the field. Hand swaged cables are for light duty applications and are NOT approved for overhead lifting. For this example we will be building a Thimbled Eye with 3/16″ Cable.

STEP 1

Refer to the Advantage Sales Catalog

Refer to the Advantage Sales Catalog for size, stock number, and number of crimps per sleeve for use with your application.

STEP 2

Gather Materials

The Advantage Sales Catalog
3/16″ Cable at your desired length
3/16″ Wire Rope Thimble
3/16″ Aluminum Sleeve
A Hand Swager and the Swage Gauge included with the Swager (for this guide, we will be using a Bench Mounted Swager – Stock # HSC-600BENCH)

STEP 3

Find the Number of Crimps, and Sequence in the Advantage Sales Catalog

For each sleeve size, there is a specific number of crimps required. Refer to the Advantage Sales Catalog for crimp requirements. For 3/16″ cable, four crimps are required.

When applying ferrules using a hand swager, always make the first swage in the middle of the ferrule. Next, swage the unswaged portion closest to the termination end. Finally, swage the portion closest to the tail end of the cable. For larger cables with more than 3 crimps, use this image as your guide for

STEP 4

Insert Cable into Sleeve

Insert the cable into one side of the hourglass shaped sleeve. Note that mechanically cut cable may begin to fray at the cut end. Feed the cable through the sleeve gently to prevent stands from fraying.

STEP 5

Form the Eye

Turn the cable back and feed it through the other side of the sleeve to form an eye.

STEP 6

Place the Thimble into the Eye

Place the wire rope thimble into the eye, and manuever the cable tightly against the thimble. To prevent the thimble from falling out, push the sleeve tightly up against the base of the thimble.

STEP 7

Note: Keep a Tail at the Dead End of the Eye

Note that properly installed sleeves have a remaining tail formed from the cut end of the cable sticking out at the base of the sleeve. This allows for full contact of the sleeve with the cable, as the sleeve expands during swaging. The length of this remaining tail should be equal to the cable’s diameter.

Now that our thimble eye is created, it’s time to swage the sleeve onto the cable by crimping it with the swaging tool.

STEP 8

Optional: Mark the Sleeve with the Crimping Order

It can be helpful to mark the sleeve in the order you are crimping, shown here.

STEP 9

Select the Right Cavity for your Sleeve

Using the provided Swage Gauge that is included with your Hand Swaging tool, confirm the proper cavity to use for your sleeve size. Sleeves should stand vertically in one cavity and fit uniformly.

STEP 10

Crimp The Sleeve

Position the Sleeve into the proper cavity of the Hand Swager, standing the sleeve VERTICALLY. Align the sleeve to first crimp mark. Compress the sleeve fully. Move the assembly to the next position and repeat the compression, leaving a space between each crimp. Repeat until the sleeve is fully crimped.

Summary

Hand Swaged Ferrules must be properly installed using the correct size fittings and tools, using the proper crimping technique, and the correct number of crimps.

WARNING

Sleeves are NOT for overhead lifting. Do not use assemblies made with sleeves for overhead lifting purposes.
Failure to carefully read and adhere to these guidelines could result in severe injuries or death.
Prior to installing sleeves, thoroughly review and comprehend these instructions.
Ensure that sleeves are paired with cable of the same size.
Follow the sleeves end termination procedures precisely as directed.
DO NOT install cable sleeves on top of the coating. Instead, remove the coating where sleeves will be swaged.
Before usage, apply an initial load test to the assembly. This load should match or exceed anticipated operating loads.

General Info

8 General Facts about Stops & Sleeves

FACT 1

Aluminum is most commonly used on Galvanized Aircraft Cable. It is the most cost-effective type of Ferrule.

FACT 2

Sleeves and stops made from Stainless Steel, Plain Copper and Zinc Plated Copper materials are the only ferrules approved for use with Stainless Steel Aircraft Cable.

FACT 3

Due to being dissimilar metals, do not use Aluminum ferrules and Stainless Steel cable together. The use of Aluminum Sleeves on Stainless Cable is NOT safe.

FACT 4

Copper and Zinc Plated Copper Ferrules ARE able to be used with Galvanized Aircraft Cable. Some people prefer Copper Sleeves because they say that the Copper flows better into the cable. Our testing shows that if applied properly, both Aluminum and Copper Sleeves are safe.

FACT 5

When applying an Aluminum or Copper ferrule using a hand swager, always follow the guide picture above for hand swaging sequence.

FACT 6

Zinc Plated Copper is used in applications where the end user doesn’t want to see the Copper Ferrule turn green. Zinc plating doesn’t last forever, but it does offer some corrosion resistance.

FACT 7

Because Aluminum and Copper are both very soft metals, they can be applied in the field using a Hand Swaging Tool. There are several tools that are used to cover the entire size range.

FACT 8

Although Stainless Steel Sleeves are rarely used, they are still available from Advantage Sales. They need to be applied by a qualified sling making professional who has the proper hydraulic equipment and swaging dies. Please call an Advantage Sales team member for more information.
