To complete our testing in independent laboratory MECASEM that achieves standardization tests of our equipment, we completed our studies on the behavior of the slackline equipment and Jumpline because current tests do not represent fairly the reality of the practice in a Using slack or jump.
The current machines we use are the same as in climbing or PPE Pro. Their tests are therefore based on several tensile tests which will break up. But in the slackline made; this is especially shocks repeated between produitent by slackeur vibration, wind, ....
And Jumpline it is worse, because the jumpeur seeks to increase the amplitude of the trickline and therefore produces more violent changes.
Thanks to the engineers we work with we could draw a parallel with the fasteners car trailers, which as Jumpline are subject to repeated shocks between acceleration and braking and especially in the same order of magnitude; of forces between 5 kN and 30 kN can be considered equivalent. As Jumpline entire force is applied mainly to one axis (bolt). . Various studies in this environment led to several standards.
The standard that interests us is that the connection bolt and the side decks, it imposes a minimum resilience with a Rockwell of C33 fullest.
To simplify: Mechanical resilience of materials characterizes the material's ability to withstand shocks, that is to say, to absorb energy and release it. plus Rockwell is low (<C1) more it can release energy without breaking and returning to its original state (eg rubber) by the most against the opposite Rockwell will be high (> C80) will be more less brittle and it will return to its original state and therefore will degrade with each shock and it will break the net.
This eliminates the use of aluminum in mechanical parts to make the strength of the assembly, aluminum Mechanical with Rockwell C40 to C53.

Blockers slackline were all broken in the screw central sheave except in banana modified with plates in aluminum.
The tests were conducted with several shackles and slings as they broke before blockers.
The plates were in 7075 Alu 4 mm machined fasteners she was 8.8 galvanized steel. The banana aluminum broke at the corner of the plate, being the place that suffered the most stress. This confirms that the more material has high resilience, energy dissipates much less brittle and therefore makes the room.
Pulley slackline | shocks 5 kN | Shock 10 kN | Shock 16 kN |

In the results must be considered an important element: the rope that has the effect of reducing the impact of the shock on the room. This is why a pulley xp2 stainless resists 60 kN more than 60 kN rhino who do not bénificie this amortized.

Manila Steel 100 kN | not tested | not tested | 43,067 | not tested |

Stainless steel shackle lyre 70 kN | not tested | 41 710 to 16 kN | not tested | not tested |
Manila textile 50 kN | 5 | 0 | not tested | not tested |
Given the results we strongly discourage the use of textile shackles Jumpline and even slackline highline or fast shocks are not dissipated in the Dyneema.
We can see that the stainless steel shackle proportionally more resilient than shackles hr, this is dù resilience of stainless steel which is lower than the high-strength steels.
