Turnbuckles – Creating Tension in Multiple Industries

Turnbuckles, stretching screws or bottlescrews are a device for adjusting the tension or length of ropes, cables, tie rods, and other tensioning systems. It normally consists of two threaded eye bolts, one screwed into each end of a small metal frame, one with a left-hand thread and the other with a right-hand thread. The tension can be adjusted by rotating the frame, which causes both eye bolts to be screwed in or out simultaneously, without twisting the eye bolts or attached cables.

Turnbuckles are most commonly used in applications which require a great deal of tension; they can range inturnbuckles mass from about ten grams for thin cable used in a garden fence, to thousands of kilograms for structural elements in buildings and suspension bridges.

Construction

Turnbuckles with various size are popularly used in construction. They combine strength and durability, yet are simple to set up and adjust. Very small turnbuckles (as light as 10 grams) might be used to support a fence in a garden. On the other hand, extremely large turnbuckles (as heavy as several thousand kilograms) are widely used as support high-rise buildings or in structures such as bridges.

Aircraft

Turnbuckles have been used in aircraft construction. Historically, biplanes might use turnbuckles to adjust the tension on structural wires bracing their wings. Turnbuckles are also widely used on flexible cables in flight control systems. In both cases they are secured with lockwire or specifically designed wire clips to prevent them from turning and losing tension due to vibration.

Shipping

Turnbuckles are used for tensioning a ship’s rigging and lashings. This device is also known as a bottlescrew in this context.

Sports

Turnbuckles find common use to tension the ropes in professional wrestling rings and boxing rings, where they serve as the attachment between the ring ropes and ring posts. Rather than the usual bare metal, here the turnbuckles are covered with padding in order to protect participants and staff. Turnbuckles even play a part in professional wrestling where they are often dramatically used by participants as part of their offensive move set.

Entertainment industry

Turnbuckles are used in nearly all rigging performed in the entertainment industry, including theatre, film, and live concert performances. In entertainment rigging, turnbuckles are more commonly used to make small adjustments in line lengths. This is generally to make a flown unit sit parallel to the stage. Another way a turnbuckle could prove helpful is with making very minor height or angle adjustments.

Pipe systems

Turnbuckles are used in piping systems as a way to provide minor adjustments for field inconsistencies. This also allows for a minimum amount of resistance when transferring the load to the support components.

Orthopaedics

A type of splint is used for upper limb to produce gradual stretching over contracted joint by its turn buckle mechanism. Used to treat stiff elbow and Volkmann Ischemic Contracture.

Stunt Rigging: Behind the Camera with an Industry Star

Stunt-Rigging

Stunt Rigging in the Movie Industry.

Article by By Mike Chalmers for Wire Rope Exchange

Many of the world’s most famous faces and personalities will garner precious amounts of camera time at the Academy Awards at the Dolby Theatre in Hollywood, California. And the films themselves will, at least for a night, finally receive their just deserves.

What probably won’t receive as much of the spotlight is the enormous amount of stunt rigging that goes into a Hollywood production. In fact, entertainment rigging is a world within a world, with its own celebrities, mad scientists, daredevils, and rock stars.

Oddly enough, Wire Rope Exchange had the great fortune to track down one of the biggest names in the world of entertainment rigging (and in this case, stunt rigging), and ask him about the ins and outs of this “world,” and what it’s like to set up and operate rigging projects that comprise some of the most talked-about films of the year — films that end up on stage in envelopes at the Dolby Theatre each February.

Keir Beck is one of the most experienced and sought after Stunt Rigger/Stunt Coordinators on Earth. With over two decades of adventure sports and climbing under his belt, and nearly fifteen years at the helm of his own

Stunt Rigging
Teamwork and comradery is the glue that keeps entertainment rigging teams safe, successful, and always at the top of their game.

entertainment rigging endeavor, Beck has become a world-renowned specialist in the Stunt Rigging and Coordinating arena. His resume is a head-turner: Matrix Reloaded, Matrix Revolutions, Casino Royale, Superman Returns, San Andreas, Narnia, Pitch Black, Sherlock Holmes, Mad Max 4: Fury Road, X-Men Origins: Wolverine, and many more.

In 2001, Beck started his own specialized rigging company — Inmotion Rigging — based in Arundel Old, Australia, with an additional location in Inglewood, California. Inmotion caters to the film and entertainment industry, working all around the world to provide creative and unique rigging solutions for both stunt and camera departments, game shows, live circus, and aerial entertainment.

We got hold of Beck while he jumped through time zones between California and Australia. Instantly likable, here’s what he had to say.

Wire Rope Exchange: You’re one of the most notable names in the industry. Can you give us a quick run-down of your job description day-to-day, and how you landed within this line of work?

Beck: My title is either Stunt Rigging Coordinator or just Stunt Coordinator. Working on a film that is heavily weighted with rigging-related stunts means that on a day-to-day basis, I would be either designing rigs from the storyboards or pre-visualization, doing safety reports, overseeing rigs going up, rehearsing, or filming. With more complex rigs, there’s a lot of time just thinking about how you can achieve what the director is asking.

Wire Rope Slings – Care and Maintenance

Wire-Rope-Sling

Terry Young, president of Construction Safety Experts, in the US, discusses identification, inspection and removal criteria for wire rope slings. The ASMEB30.9-2006 Standard requires wire rope slings to show the name or trademark of the manufacturer, diameter or size, number of legs, if more than one, and the rated loads for the types of hitches used and the angle upon which it is based.

The initial identification is done by the manufacturer and should be maintained by the user so as to be legible during the life of the sling. Replacement of wire rope slings identification should be considered as a repair and is required to be performed by the manufacturer or a qualified person. It must be marked to identify the repairing agency.

Additional proof testing is not required when replacing sling identification. An initial inspection should be performed prior to using new, altered, modified or repaired wire rope slings. It should be conducted by a designated person to verify compliance with applicable ASME 30.9-2006 standards.

A frequent visual inspection for damage must be performed by the user or designated person each day or shift the sling is used. The best safety practice is to inspect the wire rope before each use, task or lift.

Any condition meeting the ASME 30.9 – 2006 removal criteria or other condition that may result in a hazard must result in the sling being removed from service. The sling should then not be returned to service until approved by a qualified person. Written records are not required for frequent inspections.

A periodic inspection is to be conducted at intervals, not exceeding one year. This requires a complete inspection for damage to the sling by a designated person. The inspection should be conducted on the entire length, including splices, end attachments and fittings.

The frequency of periodic inspections should be based on frequency of use, severity of service conditions, nature of lifts being made and experience gained from the service life of slings used in similar circumstances or conditions.

Guidelines for the time intervals are

  • Normal service – yearly
  • Severe service – monthly to quarterly
  • Special service – as recommended by a qualified person or manufacturer
  • A written record shall be made and maintained of the most recent periodic inspection

Removal criteria

A wire rope sling shall be removed from service if conditions such as the following are present.

  • Missing or illegible sling identification
  • Broken wires
  • For strand- laid and single-part slings, 10 randomly broken wires in one rope lay, or five broken wires in one strand in one lay.
  • For cable-laid slings, 20 broken wires per lay.
  • For six- part braided slings 20 broken wires per braid.
  • For eight-part braided slings 40 broken wires per braid.
  • Severe localized abrasion or scraping
  • Kinking, crushing, birdcaging or any other damage resulting in damage to the rope structure
  • Evidence of heat damage
  • End attachments that are cracked, deformed or worn to the extent that the strength of the sling is substantially affected
  • Severe corrosion of the rope, end attachments or fittings.
  • Other conditions including visible damage that may cause doubt to the continued use of the sling

Hook removal criteria is listed in the ASME B30.10 Standard. Rigging hardware removal criteria is listed in the ASME B30.26 Standard.

The Frankensling – Custom Solutions for Rigging Dilemmas

Frankensling


The Town of Oakville Marina in Ontario had a reoccurring problem raising and lowering the masts and sails of the vessels as they handled the boats. Due the large volume of craft, the variations in size and space, they needed something that could do more than one mast or sail at a time. Enter Hercules SLR and ‘The Frankensling!

Frakensling Marina Crew
The Marina Crew

The solution they used to use was to manipulate each mast and sail individually, but this was time consuming, inefficient work. Moving multiple masts caused problems as the weight shifted as they were manipulated, became unstable and were in danger of damage. They needed something that was weight loaded to distribute an even application for the multiple height level adjusting of masts/sail raising and lowering.

The Marina came up with the solution of using slings looped together. This did not solve the whole problem, but made it more the process more efficient. There was still the strong possibility of damage as multiple slings were harder to control. The marina came to Hercules with the problem, looking for something that was efficient, robust and easy to use. Together we created what is now penned as the Frakensling.

Frakensling
The Frakensling at the Town of Oakville Marina

The sling gets attached to the mast or sail of the boat, which allows for a securing point every 12”. This Frankensling is 24ft, but it can be made to any size of specification as needed. At every 12” mark there is a loop to which a line or rigging part can be attached to ensure an even balanced load point at every stage of the moving procedure. The sling can be used at any height and the pattern modified for any type of craft or Marina.

The Frakensling in Action

This is a great multi stage variable height sling. It’s a perfect for masts that have more than 1 spreader on them. The current sling for the Town of Oakville Marina is 2” wide and 24FT long. They are looking to refine the design by shifting from 2” wide to 1” wide.

Securing loops every 12 in

It was pleasure to work with the Town of Oakville Marina, and Hercules SLR once again pulled out all the stops to custom make something that made the day to day work of our customers easier.

Doesn’t every Marina need a Frakensling?
