Decreasing the tension allows you to perform tricks and stunts. Increasing the tension gives you a slackline with similar conditions to a longline. Over time, you may want to change up the tension in your slackline to give yourself a more challenging time. When should I experiment with slackline tension? If the slackline is too tight, it will be difficult to move into an upright position once you climb on the line. Yes, a slackline can be too tight! By definition, a slackline must have some slack in the middle. Repeat the process as necessary until you find the right tension for your slackline. Take the webbing through the anchor biner on your downside and through the multiplier carabiner. You can create a multiplier using a clove hitch, using another carabiner to lock the hitch. If you want to increase the tension in your slackline, you can use a multiplier. How do I increase the tension in my slackline? Now you’re ready to go slacklining! The Ratchet: An Easy Way To Tension a Slackline There should be some give in the middle of your webbing line. The middle of your slackline should not touch the ground, but do not make the line too taut. Pull the webbing to create pre-tension on your line. Wrap the webbing through the first layer to create a more stable anchor point. Run the webbing through the anchor carabiner on your downside, then through the locker carabiner on your upper side. Install the second line locker on the other anchor sling, again threading the webbing twice before using a carabiner to lock the thread. Next, thread the webbing twice through the line locker found on one of the anchor slings and clip the open ends with a carabiner. Secure each anchor sling to the corresponding trunk using a carabiner. You should also use padded material to wrap around the trunk for protection against the friction of the slackline.Īfter wrapping the padding around the trunks and securing them, wrap an anchor sling around each trunk. The easiest way to tension a slackline is known as a primitive slackline and you can easily set it up between two trees at least 7 meters apart. You can tension a slackline using two anchor slings, two chainlinks, four carabiners, and your webbing. This means that a 90kg slackliner can safely use this slackline since it is impossible to reach that breaking load under normal circumstances. This number indicates how much a slackline’s breaking load can exceed the load capacity in a safe manner.įor example, a slackline with a load capacity of 300kg and a safety factor of 7 means that it has a breaking load of 2100 kg. You may also notice that slacklines have a safety factor. The webbing material of a slackline will determine the breaking load nylon webbings are typically stronger than polyester webbings. If a slackline is not tensioned properly, it will not be able to bear the load capacity properly and might snap even under lighter loads.īreaking load refers to the maximum weight load a slackline can bear before it breaks. Most commercial slacklines are rated for up to 300 lbs load capacity. Load capacity refers to the weight load that a slackline can tolerate. It matters because you need to be aware of your slackline’s load capacity and breaking load, especially if you are slacklining at dangerous heights.Ĭommercial slacklines display both the load capacity and breaking load specifications so that slackliners can choose the right specification for their weight. Now that you can approximate the force that you are putting on your slackline and the average tension range of a slackline, why does it all matter? This means that when a 90kg slackliner is moving along the surface of the webbing, there is a corresponding force of 0.9 kN or 9 daN being exerted on the line. In physics, forces refer to the push and pull of an object as it interacts with another.įor slacklining, this means the interaction between your foot's downward movement against the webbing's surface.įorce is measured in kiloNewtons (kN) or decaNewtons (daN), with 1kg of an object’s mass requiring 0.01 kN or 1 daN of force to interact with another object. In order to understand the physics behind slacklining, you have to know what “forces” mean.
