How to Set Up Slackline at the High Altitude?

It is a skilled task to set up the slackline at the high altitude. Today we invite the veteran player from the slackline factory and also a reliable slackline supplier to teach us how to set up the slackline at the high altitude. Be sure to wear a seat belt when walking slackline at the high altitude, and use a three- or four-meter long power rope to connect the seat belt to the slackline. Among them, when the rope is connected with the seat belt, it is directly tied to the seat belt with a figure-8 knot; When the rope is connected to the slackline, the rope is first tied in a figure-8 knot, and then the rope is connected to the flat strap with two main locks. When walking, the main lock slides on the flat strap.

When walking and falling at a height, take the initiative to grab the slackline and try not to let the protective rope be stressed, so as to avoid rapid friction between the main lock and the slackline, and prevent the slackline from being burned by the iron lock. In addition, in order to avoid the leg being bruised by the tight flat strap in the event of a fall, it is recommended to wear thicker and hard-wearing pants such as jeans. When starting at both ends, also avoid hitting the rocks when falling.

When choosing a safety belt, it is necessary to pay attention to the use of rock climbing safety belts, and the waist and leg loops should be wider. In this way, the seat belt pulls more evenly on the person when falling, and it will feel more comfortable.

The high-altitude slack line is set up very carefully, and you have to ensure the safety of yourself or other walkers. For some links with greater force, it is necessary to increase backups as much as possible to increase security.

When setting up the Slackline, two flat straps must be used on top of each other and secured with adhesive tape. Because when the walker falls, the flat belt will bear a lot of tension, and if the iron lock and the flat belt have rapid friction, it will cause a slight burn of the flat belt, so the two flat belts should be used together, so that it can not only ensure sufficient strength but also provide enough wear resistance, so as to ensure safety.

(1) The setting of the fixed points at both ends of the Slackline

When a flat strip is installed between two rock walls, if expansion bolts are used as protection points, there should be no less than 4 protection points on each side of the rock wall. Among them, two or three protection points are used as the main protection points, which always bear the tension of the flat belt, and the rest of the protection points are used as backup protection, when the main protection point is damaged, the backup protection can still ensure the security of the whole system.

Note: Expansion bolts should be used with a diameter of 10mm or 12mm and a length of no less than 7 cm. It is recommended to use 12mm expansion bolts for the main protection point. When setting the expansion bolt, the insertion depth should not be less than 5 cm, and if the rock hardness is low, a longer expansion bolt should be used. A certain distance should be maintained between the expansion bolts, and after the fixed point rope is tied, the rope should be arranged in a radial pattern and evenly stressed (as shown in Figure 3).

(2) Fixing and tightening of the high-altitude slackline

The span of the high-altitude flat belt is generally between 10 meters and 50 meters, and the tension force is about 200 kg to 500 kg when tightened, and the longer the length, the greater the tension force will be. It is important to know that when the flat belt is knotted, the tensile force it can withstand will be reduced, so the long-term stress points at both ends of the main flat belt should not be knotted, and RACK should be used to fix it (as shown in Figure 3). The connection between the RACK and each fixed point should be radial, and the angle formed by the connecting rope should be between 30 and 60 degrees, and the force of each rope should be uniform.

Note: After the main flat strap for walking passes through the RACK, the loose part of the strap should also be reconnected to the protection point to prevent problems with a certain stress link.

The tightening of the high-altitude slack line can be done using the aforementioned mountaineering equipment tightening system. As the length of the flat belt increases, so does the pulley combination for greater pulling force. Depending on the situation, two or three tightening systems should also be used to share the total tension of the main flat belt. If you use a special Slackline-specific pulley, the tightening operation can be simplified. After tightening, the end of the main flat belt should be reconnected with each protection point.

If you want to use the simple method and get a huge pull, you can choose an industrial rope tightener. Use a rope tightener to tighten, and use two or three in combination to share the tension. When using two rope tighteners, each rope tightener is subjected to about half of the tension (as shown in Figure 4). It should be noted that the industrial rope tightener can only be used as a tightening device, not as a final protection device at the same time, so at both ends of the rope tightener, use a slackline or rope to reconnect, and the main slackline must be connected with the backup protection point.
