Understanding The Mechanism Of Zip-Lines
Any person can understand the physics behind zip lines and how they work. For all purposes, understanding the technology behind it is quite unnecessary if you just want to enjoy the ride. However, if you are constructing a zip line, it is better to understand some basic principles so that you can design a pleasurable ride.
First off, zip lines need to be inclined so that the users can easily descend off a slope. Elementary knowledge of physics dictates that gravity will act upon the body that is perched upon the zip line if it is free to move and bring it down. Thus, the inclination determines the speed of the slide. Many other factors determine the speed of the slide as well, from the tautness of the string to the weight of the user and the specific environmental conditions.
This means, you might need some sort of zip line brake to bring down the speed if it goes beyond uncomfortable levels. There are different categories when it comes to a zip line brake, from simple ones that break the fall right before it reaches the lowest point to more complicated ones that gives control in the hands of the user so that they can adjust the speed themselves.
If you feel the small incline of your particular zip line will not give you enough speed, you can make changes to make it more fun! A pulley attached to the rope or cable will reduce the friction phenomenally, which automatically equates to greater speeds. However, frequent maintenance and a more sophisticated zip line brake must be installed to ensure that the user is able to stop or at least slow down when he is supposed to.
There are several ways of going down the zip-line, from a handle that a user holds on to (apart from being tied down by a safety harness) to a seat that is attached to the pulley by a carabineer that will allow you to travel down the line in a comfortable seated position.
As long as safety is one of the major concerns when designing a zip line, nothing can go wrong and the user will be able to enjoy the ride as well. However, if you do not adhere to strict guidelines, a short trip downhill might be followed with a free trip straight to the Hospital. A Zip Line brake is one of the most essential safety features in zip lines that are designed to thrill!
