Equipment

I did 6 tests in total. Following list shows the used equipment.

1.1

Lines

- Longline (white with black ends) see figure 3) - Jumpline (white) - Reggae

1.2

methods of fastening:

- Linelocker: steel Linelocker for 2, 5 cm webbing, oval Linelocker (dia: 4cm) - Sling: run in end of the Slackline - Banana (see figure 1)

Figure 1: Banana 3d The Banana is similar to slack dog. I changed the measures. Folowing figure shows the measures. The plate is 6mm strong. Screws have 12mm diameter. Inside I used some sleeves to prtect the Slackline.

Tests

2.1

Trial 1

We placed the Longline directly in between the two ankers. Distance between the ankers 240mm. The trial was stoped because the anker couldn’t fix the line. The loose splits were a bit rough so it ruined the line. The table shows the details: - maximum force - extension in milimeters - point where the line breaks trial number 1

F-max (daN) 1001, 6

extension-max (mm) 29, 04

Following Figure shows the trial before testing.

The relation between extensiondistance and force is nearly linear.

Trial 3

In this trial we used the banana. we doubled the line so we could use a shakle on one end and the banana on the other.

Figure 7: Longline: Linelocker vs. Banana, Line doubled the line broke on the shakle side. there was no bad use of the shakle. the bolt was very clear. the line didn’t touch the sides. so the line was fully attached to the bolt of the shakle. Following table gives the details:

Trial 4

we tried to fix the line with two bolts, one at each side. trial was stoped because the machine couldn’t fix the line and tight it.
