The 6x19 Classification of wire rope is the most widely used. With its good combination of flexibility and wear resistance, rope in this class can be suited to the specific needs of diverse kinds of machinery and equipment. The 6x19 Seale construction, with its large outer wires, provides great ruggedness and resistance to abrasion and crushing. However, its resistance to fatigue is somewhat less than that offered by a 6x25 construction. The 6x25 possesses the best combination of flexibility and wear resistance in the 6x19 Class due to the filler wires providing support and imparting stability to the strand. The 6x26 Warrington Seale construction has a high resistance to crushing. This construction is a good choice where the end user needs the wear resistance of a 6x19 Class Rope and the flexibility midway between a 6x19 Class and 6x37 Class rope.

The 6x36 Class of wire rope is characterized by the relatively large number of wires used in each strand. Ropes of this class are among the most flexible available due to the greater number of wires per strand, however their resistance to abrasion is less than ropes in the 6x19 Class. The designation 6x36 is only nominal, as in the case with the 6x19 Class. Improvements in wire rope design, as well as changing machine designs, have resulted in the use of strands with widely varying numbers of wires and a smaller number of available constructions. Typical 6x37 Class constructions include 6x33 for diameters under 1/2", 6x36 Warrington Seale (the most common 6x37 Class construction) offered in diameters 1/2" through 1-5/8", and 6x49 Filler Wire Seale over 1-3/4" diameter.

It"s no secret that it"s hard to find specialists to keep resorts running. From top-level electricians and IT specialists to first-rate lift and vehicle mechanics, resorts have a tough time keeping up. But there may be perhaps no greater impending shortage in the next 10 years than that for rope splicers and inspectors.

The rise of the independent splicer/ inspectors illustrates many of the changes that have occurred in the resort business as it has grown and evolved. Many began their careers working for wire rope manufacturers where they learned the art of splicing. When liability issues became large in the 1970s and 80s, wire rope companies looked to shed risk. At the same time, liftbuilding slowed. Faced with layoffs, many splicers became independent operators.

Inspector/splicers are essential because they ensure the viability of the wire ropes that carry riders uphill. Not that wire ropes are prone to problems; there"s not much wear on ropes. But eventually they weaken from the bending that occurs as they go around the bullwheels. Such wear takes place slowly, over many years. On fixed-grip lifts, the ropes can last 30 to 40 years. On gondolas and detachable chairs, which make round trips (and go around the bullwheel) twice as often, the ropes last 15 to 20 years. "Cables don"t fail catastrophically," says Richard Ryer, a splicer and inspector with 45 years of experience. "They give you plenty of warning."

There are less than a dozen inspector/splicers who service the several thousand lifts in the U.S., from Randy Blenis in New England to Ryer in Tahoe. This cadre is highly talented; many have been in the business for 25 years or more. But that"s also the problem. Most of these old hands are nearing retirement, if their 401ks ever recover. And there are few younger splicers coming along behind them.

That"s an issue, because the need for quality is higher than ever. A poor, rough or bumpy splice causes faster rope wear and a bumpier, slower ride for passengers-the bumps add shocks to the rope, which can trip the system.

Inspections consume most of the time of the inspector/splicers. Ski lift haul ropes are inspected yearly. Mostly, this involves visual inspections of the ropes, but codes now require some electromagnetic testing. In both cases, though, inspectors check out the condition of the splice and of the rope itself at random intervals.

takes a practiced eye to do a proper visual inspection; damage, primarily broken wires in the rope, often occurs on the inside. That makes visual inspection as much art as science. "I look for anything that"s abnormal," Ryer says. "It"s hard to describe."

What sorts of abnormalities might turn up? "Occasionally you find a lightning strike that requires a repair right away," says Randy Blenis, who"s been building lifts and splicing wire ropes since the mid-1970s. "In bad cases, you might have to replace the rope, but often you can replace the strand that"s broken. On two occasions, I found a rope hit by a bullet."

Inspectors also note how the rope wears over time. "We keep a track record of the rope," says Blenis. "You get broken wires, especially in the tucks. The crown and length of lay will change slowly." This last indicates stretching.

The splices themselves are important, too. First, when a rope is installed, the splice is what takes a single long wire rope and turns it into a continuous loop. A smooth and strong splice provides for a longer rope life, smoother ride, and thus fewer stops. In addition, over the course of time, as wire ropes stretch, it is often necessary to shorten them by resplicing. This might be done up to four or five times over a rope"s life.

Splicing has been, for many, a family business. Of the the current splicers, Richard Ryer, Danny O"Connor, and R.J. Knight learned from their fathers. Bill Alsup learned from another father-and-son team, Poma founder Jean Pomagalski and his son Bernie. Norm Duke learned from Bill Diener, a contemporary of those early splicers. Dale Walters learned the trade at Paulson, an American wire rope company, and later taught Randy Blenis.

Today, the family tradition has continued. Walters has trained his son-in-law, J.T. Anderson, to do both inspection and splicing, and his daughter Whitney to be a wire rope inspector. R.J. has trained his sons, Justin and Jason. Randy Blenis is teaching his son, Brandon. One exception: Bill Alsup has trained Terry Zakotnik, VP of operations for the Palm Springs Tramway, to replace him as the 71-year-old Alsup scales back.

Danny O"Connor"s story is typical. "I started working for my dad when I was 14, 16," he says. "I"m now 62. My father was one of the old timers in the ski business. He got involved when they brought the first T- and J-bars from Europe, in 1936. I always thought I would do something else, because this work is way too hard." Instead, he inherited O"Connor Ski-Lifts, which he still owns.

They all have their strategies for dealing with the traveling lifestyle. Blenis simply chooses to keep his travel to a minimum. He limits his splicing and inspections to the customers of his Ropeway Construction company, which focuses on building lifts.

With so few splicers and so many lifts to work on, there"s competition among splicers-but it"s a friendly competition. "R.J., his family and mine have been in competition for 60, 70 years," says Ryer. "Our dads started up the business right after World War II. But we"re good friends. We talk to each other whenever we have problems."

That might not be the case in six, eight, or 10 years. "The industry will be screwed," says Duke. "There are lots of ropes 30 to 40 years old, a lot of them will have to be replaced in the next 10 years," Walters adds. The consensus is that some of the work will be done by splicers from Europe, where many are still employed by the rope manufacturers. "But when crunch time comes, they will be busy in Europe," Walters says.

Splicing is a combination of art and craft. The length of the splice and of the “tuck tails,” where the ends of the individual strands of the splice are tucked (woven) into the rope, are determined by the diameter of the rope: splice length is equal to 1200 times the diameter, and tuck length is 30 times the diameter (or up to 100 times, in the case of rope manufacturer Fatzer’s own specs). For a typical detachable, with a 1 5/8-inch rope, the splice must be about 175 feet long. That takes a “crew of 12 to 15 people, who we recruit mostly from lift maintenance and ops,” says R.J. Knight. Where possible, they also bring in students from Colorado Mountain College’s resort management program. The crew helps handle and maneuver the rope while the splicers handle the critical work.

Haul ropes on ski lifts consist of six strands of wire wrapped around a core. Splicing involves overlapping the ends of the rope, then entwining three of the six strands from each of the ends to marry them.

Alsup says that the hardest part of the job to learn is making a smooth tuck. While it can take time to unlay a strand from one end and replace it with a strand from the second end, once that process gets started properly, it flows along. “The tucks are hard, that’s where the craftsmanship comes in,” he says. “Starting the marriage is like putting a nut on a bolt. If you get it started right, it goes easy.”

Consider a 1 1/2 inch rope. By code, the splice length must be 1200 x 1 1/2 inches, which comes out to 150 feet (splicers often add an extra margin, but let’s ignore that for the moment). From the marriage, the center point where the splicing begins, “you run your splice 75 feet in each direction,” says Alsup. Out toward the ends of the splice, each of the strands are cut and tucked into the rope, with the tuck points staggered to avoid creating a weak point. “To get that tail into the rope, you remove the core and put the strand in. Where the strands cross, that’s the tuck point. And that’s where the craftsmanship comes in.” With a 1 1/2-inch rope, the tuck is 45 inches long. The core is cut and removed, the strand is straightened and fit into the void, and the other strands are laid over it.

Sounds simple enough, but the wire strands are not easy to work with. The larger the ropes, the harder they are to shape. “You have to get it right,” Alsup says. “If you have a lumpy tuck, you can’t just beat it into submission.” And getting it just right is the trick.

“The quality of the tucks are better than they have ever been,” says Richard Ryer. “Due to detachables, they have to be.” That’s because the higher speeds of detachables magnify the effect of any flaws and cause the rope to wear faster, and also cause more vibration and therefore more stops.

It’s easy to overlook cable, but doing so is unenlightened in relation to the technological accomplishment. Utilized for supporting bridges and controlling elevators, cable cars, and aerial tramways (ski lifts, gondolas, etc.), the helical series of metal wires—whose tensile strength outperforms that of the fibrous counterpart (rope)—are a modern marvel.

So, what exactly is cable? Wire rope consists of three basic components: wires, strands, and a core. The core functions to provide proper support for the strands. Wires wound together concentrically in a helix to form the strands, which in turn also wrap around the core helically. The core does necessarily need to be composed of steel or other metals; instead, it can be a fiber core.

However, these characteristics are what we understand as wire rope. Cable is, in fact, different. Technically, cable is not the same thing as wire rope but a smaller version of the same material—3/8” or less, to be exact. Similarly, the common wire rope construction of 7 x 7, 7 x 19 is known as galvanized cable or aircraft cable.

Therefore, while cable actually does not include wire rope sizes greater than 3/8”, the term’s usage is generally a matter of preference for the industry or application.

The nomenclature for cable or wire rope is structured around describing the number of wires contained within the strands and their relationships to each other in the particular product. For example, 7 x 19 describes seven groups of nineteen wires, and 6 x 25 similarly indicates that the wire rope contains six strands with twenty-five individual wires on each. Wire rope is also classified by the core type, the lay of the strand, and the preforming (the forming of the individual wires of a strand into a helix to enable them to retain their shape as a uniform cylinder after being cut).

As for the attainable tension, it is dependent on numerous factors incorporated into the cable’s design, and certain cables should be used for their intended purposes. Of course, it is a necessity to assure that cables or wire ropes do not break during use. ANSI B77.1-2022 addresses this as the factor of safety, or “the ratio of the nominal breaking strength of the rope and the maximum static design tension of the rope.”

For example, the standard calls for new wire ropes in tension systems to have a minimum factor of safety of 6 and new haul ropes to have a minimum static factor of safety of 4.5.
