Swaged Cable

Showing all 7 results


The Swaged Cable is 7 x 19 strand aircraft cable. Factor pre-cut & swaged. Moderate corrosion resistance & remains ductile over long periods running over sheaves.  The most commonly used cable for boat lifts.

BH-USA recommends 7 x 19 aircraft cables for boat lift applications. 7 x 19 means the rope has seven strands and there are nineteen wires in each strand. Always consider at least a 5:1 safety factor when figuring working loads. A test certificate for all cables sold by BH-USA is available upon request.

7 x 19 aircraft cable is not suitable for use in aircraft controls.

Aircraft Cable

Aircraft cable is specified by the number of strands in the rope times the number of wires in each strand. “7 x 19” means the rope has seven (7) strands, with 19 wires in each strand. 7×19 is the most flexible aircraft cable construction.

Swaging

Swaging is a method of securing wire rope or aircraft cable with a permanently applied fitting or sleeve. The swaged connection will exceed the rated breaking strength of the wire rope or cable when properly applied.

How much will my cable hold?

Stainless Cable

Galvanized Cable

Cable Size Cable Type Lifting Capacity
3/16 in. Stainless 1,050 lbs. / Drop
1/4 in. Stainless 1,750 lbs. / Drop
5/16 in. Stainless 2,450 lbs. / Drop
3/8 in. Stainless 3,600 lbs. / Drop
Cable Size Cable Type Lifting Capacity
3/16 in. Galvanized 925 lbs. / Drop
1/4 in. Galvanized 1,600 lbs. / Drop
5/16 in. Galvanized 2,250 lbs. / Drop
3/8 in. Galvanized 3,000 lbs. / Drop

The drop is the individual piece of cable from the boat lift to the sling or cradle. Boat lifts have a minimum of 4 drops straight line and 8 drops compounded. The cable must be 7 x 19 aircraft-grade and less than 2 years old. These ratings drop after 2 years and all cables should be replaced after 2 years. What size boat lift cable do I need to lift my boat? Any boat heavier than 6,000 lbs. needs the boat lift cable to be compounded. We use the ASME (American Society for Mechanical Engineers) recommended safety factor and rating system, which is the same used in the overhead crane industry. Never use “Breaking Strength” for rating a cable.
