A zipline appears simple to install, but it is not.
To start, you must decide if the area where they are installed complies with safety requirements. The most important points of a zipline are the anchors, which are the points where the cable attaches. You can attach the cable to concrete foundations, large rocks, trees or other strong point that supports a minimum of 8 tons to the breakdown for ziplines smaller than 50 meters or less. Ziplines USA evaluate the resistance of these anchor points or build new anchor points.
Another important point is to calculate the catenary or the arch must have the cable for proper operation. If the zipline cable is tensioned too much, shortens the useful life of the zipline, there is a risk, of breaking the cable by excess tension and no speed reduction for the Tyrolean braking at the end of the course. If the a zipline cable is too loose, without tension, many people have jammed in the middle and the change in weight of a person affect the total travel, seen clearly affected heavier, early in the course of the zipline have a very fast speed, but in the end will be a hard braking and, that cause, not extending to the end and get caught in the middle of the zipline.
Another important factor is the inclination of the zipline over the entire length, if the angle is minimal will be impossible to reach a person on the other side of the zipline, and if the slope is too large, we are exposing people to arrival too strong and violent, that cause accidents or injuries occur.
Is important to mention that a zipline is not just a cable stretch for throw human lives to see what happens, NO! It must have the experience and choose all the elements of a zipline properly and appropriate to provide security and prevent any accident.
