Update about the PARALOCK

Trennkarabiner

Lightweight, safe, just as convenient to use as a conventional paragliding carabiner – and yet more durable and separable under load. This is the current status of the Paralock pre-series.

In terms of safety, stregth and function, the current Paralock pre-series is faultless.

We have ensured this through extensive testing. The first flights with prototypes by Tom Grabner and other test pilots were still made without a security cap.

 

 

However, after it became apparent that an unintentional opening due an accidental push of the release mechanism is unlikely but still possible, we added the security cap as an additional safety step. The paraglider can still be disconnected in seconds, even under load.

However, there is still room for improvement, and the currently available pre-series is also not yet flawless in terms of visual appearance.

The current manufacturer has to date not been able to deliver the quality we require for mass production. As a result, each Paralock is being completely disassembled in our Munich workshop and some parts have to be extensively reworked. The costs of production still far exceed the achievable revenues. Not even taking into account our investments in forging molds and machining equipment.

Nevertheless, also based on the knowledge gained with the pre-series, we are in the process of completely revising the design of the Paralock and restarting production with a different manufacturer. Just like our Quick-Out, the Paralock has to be forged in a complex two-stage process that only few companies can master. Based on our experience, we do not expect the new Paralock generation to enter the market for another one to three years, due to the overall very high complexity of the product.

But when it will be available, we want to offer an upgrade to the new generation at a 50% discount to all pilots who have purchased a pre-series Paralock and thus helped to finance this challenging project.

Risk of material fatigue in air sports carabiners with conventional snap gate

White Paper
Dipl. Ing. Thomas Finsterwalder, Juni 2020

Conventional carabiners have a snap gate, for whose frictionless movement a certain amount of gate play is required. Depending on the size of the play, form fit on the side with the closure only occurs at a load of 30 to 150 kg. The side facing away from the closure is thereby exposed to relatively high tensions. Due to the oscillating load, which permanently affects air sports carabiners during flight, there is a risk of material fatigue in this area. In the following, we explain the background of the problem and describe how the strength of some currently used conventional paragliding carabiners is tested by a uniform method. It turns out, that fatigue strength for a time span of 5 years is not always given, and that there are very different ways to achieve it with regard to carabiner design.

Risk of material fatigue in air sports carabiners with conventional snap gate [PDF, 506 KB]

 

Almost all connecting links between pilot and wing, that are currently used in air sports, are carabiners with a snap gate as known from mountain sports. These carabiners are popular, because they are easy to handle and the automatic locking of the snap gate largely excludes any maloperation. Also their low weight at high breaking loads and the small dimensions make them attractive for hang glider and paraglider pilots. In addition, the production of such carabiners is relatively inexpensive. We, too, manufacture conventional carabiners, although we have been developing alternative air sports carabiners in parallel since 1993.

It should, however, be noted that carabiners are not only exposed to static, but also to dynamic loads during flight, which in the long run can lead to material fatigue. Material fatigue would necessarily only occur, if the critical stresses are excessively exceeded. But since the snap gate becomes form-fit before, this is prevented. But still, a certain probability of occurrence remains. It tends only slowly towards zero, depending on the size of the gate play and the number of load changes. This also explains why to date only a few cases have become known in which carabiners broke during use due to material fatigue, although hundreds of thousands of conventional carabiners have been used in air sports since the 1970s.

However, the danger is that a fatigue fracture usually occurs suddenly and without warning.

Infinite fatigue strength is actually standard in engineering, especially in aviation. Due to the problem of gate play, however, there is to date no compact conventional carabiner with infinite fatigue strength. One of the reasons is, that it is difficult to guarantee a low form fit point. Only limited fatigue strengths of 5 years have been achieved so far. But limited fatigue strength involves the general problem that it is not possible to tell how many load changes a carabiner has already endured, and many pilots do not seem to be aware of the potential danger of using it too long. Just recently, at the beginning of 2020, the case of a fatigue fracture in Slovakia became known, in which the maximum allowed operating time of the carabiner was exceeded (see the expert testimony by the Ministry of Transport and Construction of the Slovak Republic of March 26, 2020).

Since standardized tests are still lacking, manufacturers currently apply own test methods and consider different safety factors when determining fatigue strengths. The strength tests described in the following on some currently common paragliding carabiners show, that this practice leads to very different results. We have carried out these tests during the development of our own air sports carabiners for comparison purposes.The tests have been carried out with unused carabiners according to the method described below. It turns out that fatigue strength for a time span of 5 years is not always given, but that there are very different ways to achieve it with regard to carabiner design.

 

 

cic-alu-xCIC aluminium carabiner

Aluminum carabiner of the Taiwanese manufacturer CIC, as it is currently used in various harnesses.
Weight: 60 g
Static breaking load: 2 000 DaN
This carabiner withstood 2 000 load cycles with an upper load of 252 DaN and then broke after 68 000 load cycles with an upper load of 115.4 DaN. A limited fatigue strength of 5 years for mono paragliding use is not given. The aluminum carabiner has a rather wide belt support, which in combination with too much gate play led to exceeding the permissible tensions.

 

camp-alu-xCamp aluminium carabiner

Aluminum carabiner of the Italian company Camp, as it is currently used in harnesses from Woody Valley.
Weight: 46 g
Static breaking load: 2 000 DaN
This carabiner withstood 2 000 load cycles with an upper load of 252 DaN and then 5 mio. load cycles with an upper load of 115.4 DaN. The very light aluminum carabiner has a rather wide belt support. Since it is relatively flexible, the gate becomes form fit already at low loads. A limited fatigue strength of 5 years for mono paragliding use is given.

 

edelrid-alu-xEdelrid aluminium carabiner

Aluminum carabiner "Forsas" of the German company Edelrid, as it is currently installed in harnesses from the company Advance.
Weight: 51 g
Static breaking load: 2 300 DaN
The carabiner endured 2 000 load cycles with an upper load of 252 DaN and then 5 mio. load cycles with an upper load of 115.4 DaN. With this relatively stiff carabiner, form fit occurs rather late. Due to the extremely narrow belt support, however, this carabiner still has a limited fatigue strength of 5 years for mono paragliding use.

 

supair-stahl-xSupair steel carabiner

Carabiner made of stainless steel from Supair, as it is still available today.
Weight: 132 g
Static breaking load: 2 400 DaN
The tests in 2005 had been carried out with a lower oscillating loads. This carabiner endured 1 mio. load cycles with an upper load of only 40 DaN and then broke at approximately 740 000 load cycles with only 50 DaN. The measured form fit point was reached at 81 DaN. To achieve limited fatigue strength, form fit would have to be reached at less than 50 DaN.Since steel has a three times higher stiffness than aluminum, it is particularly difficult for conventional steel carabiners to achieve a low form fit point.Even in two further tests carried out in 2005 with closed gate, the required limited fatigue strength of 5 years for mono paragliding use according to the method described here was not given.

 

finsterwalder-titanal-xFinsterwalder-Charly Titanal carabiner

The "Snaplock" made of Titanal is produced by us since 2009 for various harness manufacturers.
Weight: 76 g
Static breaking load: 3 000 DaN
The Snaplock withstood 2 000 load cycles with an upper load of 252 DaN and then 5 mio. load cycles with an upper load of 115.4 DaN with open gate. Since the test was carried out with the gate open, it is not relevant that form fit occurs late with this carabiner. Due to the high strength of the carabiner body, the limited fatigue strength of 5 years for mono use is given in any case.

 

 


Additional information

What is the reason for material fatigue in conventional carabiners?
For a frictionless movement of the snap gate, there must be a play between the nose of the carabiner and the gate. Due to the manufacturing process, this play has a variation range which cannot be exactly defined. Within the play, the carabiner is being stressed as if with the gate open. The load bearing system corresponds to that of an open ring. Depending on the size of the gate play, the material used and the dimensions of the carabiner, form fit of the gate is given only at a more or less strong load. Then, the load-bearing system is that of a closed ring.

Therefore, when dimensioning the carabiner, two different load cases must be considered: within the gate play ("open ring") and form-fit ("closed ring"). Depending on its width, the lever arm of the carabiner's belt support increases the tension by a factor of 20 to 35 in the load case "open ring" compared to the load case "closed ring". Due to the high tensions in this load case, to date no manufacturer has succeeded in designing a conventional carabiner with small dimensions that has infinite fatigue strength.

How can a carabiner´s fatigue strength for a time span of 5 years be tested?
It is necessary to determine the resistance by means of fatigue tests. A special test method has been developed for this purpose. It uses the findings of the SincoTec test specification 05781 of February 22, 2006, which is based on fatigue tests of various air sports carabiners in 2005 (see the SincoTec test report 05601 of June 13, 2005) (both documents are only available in German):

  1. As infinite fatigue strength (without considering safety factors) for the load case "open ring" (open gate), values between 21 and 90 DaN were determined for conventional paragliding carabiners. The examined steel paragliding carabiners had no higher fatigue strength than the aluminum paragliding carabiners. Infinite fatigue strength is given if the upper limit of an oscillating load is endured 2 mio. times for steel carabiners and 5 mio. times for aluminum carabiners.
  2. For the conventional carabiners examined, form fit was provided only at loads of 15.5 to 214 DaN.
  3. It has been determined, that the upper loads during normal thermal paragliding flight at a total flight weight of 100 kg are 60 DaN. During extreme manoeuvres, values of 210 DaN have been measured. The carabiners should be designed for a total flight weight of 120 kg in mono use and 250 kg in tandem use.
  4. According to the DHV, the frequency of load changes during normal flight is about 37 times per minute. A maximum of 2 000 extreme manoeuvres within 5 years is assumed.

Based on these findings and assumptions, and assuming a safety factor of 1.145 for scratches plus a general safety factor of 1.5, the following procedure results for a carabiner fatigue test with closed gate and a limited fatigue strength of up to 5 years in mono use:

2 000 load cycles with an upper load of 252 DaN, subsequently 5 mio. load cycles with an upper load of 115.4 DaN for aluminum carabiners. For steel carabiners, 2 mio. subsequent load cycles are sufficient.

For a limited fatigue strength of 5 years in tandem use, 2 000 load cycles with an upper load of 525 DaN and subsequently 5 mio. load cycles with an upper load of 240.5 DaN must be endured by aluminum carabiners.

For steel carabiners, 2 mio. subsequent load cycles with an upper load of 240.5 DaN are sufficient.For the proof of infinite fatigue strength according to the general rules of aviation with a failure probability of 1%, the carabiner would have to endure the required 2 or 5 mio. load cycles with an upper load of 432.8 DaN in mono use and 901.7 DaN in tandem use.

PARALOCK separation carabiner

Lightweight paragliding carabiner with convenient handling and long replacement interval for mono and tandem use

With a conventional paragliding carabiner, separation under load is hardly possible. However, in certain situations this can not only be useful but even life-saving - e.g. when landing in moving water or in strong winds.
Also after an emergency parachute deployment, it may be necessary and in any case recommended to disconnect the paraglider. The Paralock eliminates the need to carry a line cutter or to pull in the paraglider which costs valuable time.
The Paralock's separation function is also useful in other sports, for air and water rescue, and in parachute harnesses.

Features:

  • Working load limit (air sports): 115 DaN* per carabiner
  • Drop-forged from Titanal, 76 g
  • Breaking load: 3 000 DaN
  • Breaking load, open gate: 2 000 DaN
  • Load without permanent deformation, open gate: 1 600 DaN
  • Inside height: 60 mm
  • Suitable for belt widths 25-30 mm, tucked in up to 45 mm


* 1 daN (Dekanewton) = 10 N (newton)  ≈ 1 kg

  • 5 years replacement interval for PG mono use and 2 years replacement interval for HG and PG tandem use with unimited flight hours.
    In a dynamic fatigue test with open gate, the Snaplock withstood 5.000.000 load cycles at 115 daN as well as 2.000 load cycles at 240 daN.

  • Lightweight and safe:
    Snaplock carabiners are drop-forged instead of bent which results in increased material strength. The material of bent carabiners, in contrast, is weakened by inner tensions in the bended areas.
    With an open gate breaking load of 1.600 daN, the Snaplock can bear approx. four times more load than conventional paragliding carabiners. Snaplock carabiners weigh a mere 76 g and thus save approx. 150 g of weight compared with steel carabiners.

    * 1 daN (Dekanewton) = 10 N (newton)  ≈ 1 kg

  • Convenient:
    snaplock-naseThe Snaplock's conventional twist lock is easy to operate as the locking sleeve does not need to be pushed down to open the gate. The carabiner is self-locking after releasing the sleeve. 

    As the counterpart of the snapper is closed, the risers cannot get caught whilst hooking in and out.

  • Universal fit:
    The Snaplock is suitable for band widths of 25-30 mm and narrower, but also accomodates the previously common 44 mm webbings if they are tucked in (see assembly instructions for 44 mm wide webbings).

  • Non-twist:snaplock-eingebaut2
    Thanks to its distinctive "nose", the Snaplock can be attached to the harness in such a way that a sidewise turning is reliably prevented. Moreover, harness manufacturers have the possibility to use the nose for back strap attachment. Back support can thus be significantly improved.

 

More information on the fatigue endurance of air sports carabiners...
Paragliding carabiners are subject to permanent load changes during flight. Measurements by the DHV show that they can amount to between 10 and 110 kg and more, depending on pilot weight, pilot flight behavior and thermals, and that they can occur up to 26 times per second. Given the carabiners' high breaking load (at least 1.500 kg), such load changes should generally be unproblematic. However, conventional carabiners exhibit a construction-related peculiarity: their play in the gate. This play is necessary for the snap hook to open and close frictionless. However, the snap hook is force-locked only at weights of 30-120 kg (depending on the amount of play in the gate). As a result the pilot flies as if the carabiner lock was open within the range of the play in the gate. Since the carabiner construction - as practice and dynamic fatigue tests show - is not designed for such load cases, already the relatively low operating load during normal flight operations can lead to breakages due to material fatigue. As the play in the gate cannot be reliably limited and as it is difficult to control, we have constructed the Snaplock in such a way that it is fatigue endurable also within the range of the play in the gate. Please note: Not all carabiners are tested for fatigue endurance. Special caution is required when the carabiner manufacturer does not give information about the replacement interval.

Steel is good ?

The fatigue endurance of carabiners is not a question of material but a question of design! In dynamic fatigue tests, some aluminum carabiners exhibited substantially higher fatigue endurance levels than steel carabiners. Although stainless steel is generally more fatigue endurable, harder and more resistant to corrosion, the difference in strength can easily be outweighed by a larger width of the aluminum component. Due to the better strength-to-weight ratio, high-quality aluminum alloys are the standard in aircraft construction.

  • Inside height: 40 mm

    For the Pin Lock carabiner, fatigue strength is not an issue, as its closure is form-fit. In the test, the Pin Lock withstood 5 000 000 load cycles with an upper load of 425 DaN without damage.
  • Lightweight and safe:
    Pin Lock carabiners are drop-forged instead of bent which results in increased material strength. The material of bent carabiners, in contrast, is weakened by inner tensions in the bended areas. However, the Pin Lock weighs a mere 80 g, i.e. only approx. half the weight of a steel carabiner.
  • Separate strap chambers
    Separate strap chambers prevent the carabiner from twisting.  
  • Handling:
    The risers are attached to the Pin Lock in a similar way as to conventional carabiners. The Quickpin lock features an automatic locking mechanism. It is designed in such a way that two different hand movements are required to unlock the carabiner: Pushing the release button and pulling out the bolt in the opposite direction.

    Releasing the risers after landing is easier with Pin Locks than with snap hook carabiners. To ensure the proper connection between risers and carabiners in extremely strong wind conditions, the glider has to be attached to the carabiners before putting on the harness. This applies to both conventional carabiners and Pin Lock carabiners.

    When used according to the instruction manual, icing problems can be reliably prevented even in extreme winter conditions.

pinlock detail   1. Quickpin
Self-locking ball lock pins are being used in aircraft construction already for many years. Several hang glider manufacturers incorporate our Quickpins into their A-frame corners and pilot hang-ins. In rehab technology, more than 1 m of our ball lock pins are in trouble-free operation.

2. Carabiner body
Unlike conventional carabiners, Pin Locks are drop-forged from Titanal instead of bent from round steel rods and subsequently embossed. While bending tends to weaken the carabiner material, drop forging results in significantly improved material hardness. The strength level of the Titanal used is comparable to that of high quality stainless steel. However, at only about one third the weight! Titanal is also used for highly stressed aircraft and rocket components.
 3. Safety cord

The safety cord of the Quickpin ist made of high-performance nylon developed by DuPont for deep sea fishing. The safety cord is replaceable and lasts for years when installed and operated properly.

Quickout paragliding carabiner

Special carabiner that enables quick release under load

 

Features:

  • In emergency situations, fast disconnection without effort is possible
  • Four safety steps with the possibility of gradual unlocking
  • Form-fit and fatigue resistant
  • Replacement interval: mono and tandem 8 Jahre, unlimited flight hours
  • Working load limit (air sports): 400 DaN* per carabiner
  • Body drop-forged from Titanal, insert made of high strength aluminum alloy 7075 T6, 200 g
  • Breaking load: 4.000 DaN, individually tested to 2.000 DaN
  • Inside height: 40 mm

The Quickout is used everywhere where a reliable connection and if needed a quick release even under load is necessary. It is designed for secure load attachment - in particular for the carrying of persons - and is suitable for outdoor use.

There is no specific CE standard for separation carabiners. However, the Quick-Out is a central component of different certified special harnesses, which are used and proven nationally and internationally in many applications, e.g. in helicopter missions by the police, military, mountain rescue and fire departments.

In paragliding sports, it allows the release of the glider when used with a steerable rescue system.

The simultaneous push of both lock buttons disconnects the pilot from the glider effortlessly. Safety trainings showed the release of the glider to be advantageous in the case of a rescue system deployment.

Aside from its advantages in the case of water- or tree landings and in strong wind conditions, the Quickout also offers superior handling compared to conventional paragliding carabiners.

Also after an emergency parachute deployment, it may be necessary and in any case recommended to disconnect the paraglider. The Paralock eliminates the need to carry a line cutter or to pull in the paraglider which costs valuable time.
The Paralock's separation function is also useful in other sports, for air and water rescue, and in parachute harnesses.

Gleitschirm Karabiner

Lightweight and durable

The Paralock weighs only 73 g and is equally suitable for Hike & Fly as well as for tandem paragliding.
Due to their form-fit design, the Paralock and the Quick-Out are to date the only air sports carabiners that have been able to demonstrate an approved replacement interval of 8 years for mono use and 5 years for tandem use. The Paralock is also suitable for use in hang gliders, where the replacement interval is 5 years. The number of flight hours is unlimited within the replacement interval.

Gleitschirm Karabiner

Convenient handling

Easy operation even with gloves: After inserting the paraglider risers, the Paralock locks and secures itself automatically. The carabiner is opened by a 120° turn of the release lever against spring force, whereby the lever can only be unlocked after a button is pushed.

A security cap over the release button reliably prevents the Paralock from being opened unintentionally.

5 reasons why the paraglider should be disconnected after an emergency parachute deployment

    1. According to the LTF, the maximum allowed sink rate for paraglider rescue systems is 6.8 m/s, corresponding to 24.5 km/h. However, many pilots are not aware that in the reserve parachute certification process, the sink rate is determined without the paraglider. Interactions between paraglider and rescue system can increase the sink rate substantially – for example, by increased swinging or due to a resulting shear position. The risk of injury increases accordingly.
    2. Although modern reserve parachutes usually reach maximum sink rates of "only" 5.5 m/s, corresponding to approx. 20 km/h, these values are often only achieved by a lateral drift that generates lift. A paraglider that is not separated or only separated on one side impedes this drift and thus substantially increases the sink rate.
    3. The possibility to choose the landing site with a steerable rescue system is a significant safety plus. If the main glider is not separated, this safety advantage is foregone.
    4. It has shown that a separated paraglider usually collapses very quickly and that its salvage is easier. In the case of a tree landing, there is also a much lower risk of damage to the glider when it does not carry the full pilot weight.
    5. Video of a downplane situation of the paraglider after an emergency parachute deployment

Easy attachment to almost all paraglider harnesses 

The V-shaped belt chamber for the harness is designed to correspond to the pulling directions of the main risers and the back strap.
In some pod harnesses, the pod is attached separately (e.g. in the Advance Impress 4). The pod loops can be inserted above the harness chamber separating screw.

Charly foot accelerator separation systems:

Die Befestigung der Gleitschirmtragegurte ist ähnlich wie beim konventionellen Karabiner. Der Quickpin-Verschluss verfügt über eine automatische Verriegelung. Er ist so gestaltet, dass zum Öffnen zwei unterschiedliche manuelle Handlungen erforderlich sind: Das Drücken des Entriegelungsknopfs und ein Ziehen des Bolzens in entgegengesetzter Richtung.
 
Das Lösen der Tragegurte nach der Landung ist beim Pin Lock einfacher als beim Schnappverschluss Karabiner.
Damit bei extremen Starkwindverhältnissen ein ordnungsgemäßes Befestigen der Tragegurte am Karabiner sichergestellt ist, muss der Gleitschirm vor dem Anlegen des Gurtzeugs am Karabiner befestigt werden. Das gilt für konventionelle Karabiner wie für Pin Lock.
 
Bei Beachtung der Betriebsanleitung können selbst im extremen Winterbetrieb Vereisungsprobleme zuverlässig vermieden werden.

A foot accelerator separation system is required to allow the main canopy to be completely separated after an emergency parachute opening. The foot accelerator separation systems work automatically after the karabiner is opened. Charly offers 3 foot accelerator separation systems.
