  • Commercial Grade 7 x 19 Aircraft Cable

5/16″ Galvanized Wire Rope Cable

The 5/16″ Galvanized Wire Rope Cable is a 7 x 19 strand aircraft cable. Moderate corrosion resistance & remains ductile over long periods running over sheaves.  Galvanized steel cable is stronger than stainless steel cable. The most commonly used cable for boat lifts. Made by BH-USA.

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.

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.

NOT FOR LIFTING HUMANS

No product can operate indefinitely at its rated capacity. Wire rope and Cable must be inspected regularly for any deterioration which may result in the loss of original strength. Users must determine whether further use of the rope would constitute a safety hazard to life or property. Lubricate operating ropes regularly. Keep out from under any raised loads and keep out of the line of force of any load. AVOID SHOCK LOADS. Due to the uncontrollable situations in which this cable is used after the purchase, BH-USA cannot warranty or be held liable for cable past the purchase date. It is the responsibility of the ultimate user to determine a working load limit for each application. Many factors should be considered: included among, but not limited to, loads applied, speed of operation, acceleration or deceleration, length of rope or cable, shock loads, abrasion, corrosion, number, size, condition and location of drums and sheaves, facilities for inspection, and the danger to life and property should a rope or cable break. Wire Ropes and Cables must be stored, used, lubricated, and maintained in accordance with normal safety standards; and must be properly designed, maintained, and operated. Inspect regularly. Do not kink, knot, or crush. Do not ever use wire rope sold by or made by BH-USA to lift humans in any way.
