Different Zipline Kits
Your basic zipline kit comes with a stretch of aircraft cable, fittings and connections, a trolley for the rider, and something like a handle for balancing. A more comprehensive rig would have a seat, brake block, harnesses and helmet as well. Here is a look at the different zipline constructions, and how safe each is.
How a professional kit differs
Professional zipline makers intend their wares for commercial installations instead of in homes, and that comes with an elevated safety requirement. Engineers prescribe 3/8” to 7/8” aircraft cables based on the length of the ride, and the tautness of the cable. A backyard zipline kit would need a cable no thicker than 1/8” to 3/8”. If a shorter zipline is not installed too taut, smaller cables are safe enough to use. The thickness simply gives additional safety and makes the ride smoother, but backyard rides are over too soon to for you to need either.
“Hold on” Kits and “Harness in” Kits
These have different ways of holding the rider to the trolley, with the “Harness in” method being decidedly safer. Gates and locks can be installed to keep people from tampering with the zipline, for the times when you are not at home. It is possible to get hut even with a harness on, if it has not fitted or clipped on properly.
Your basic home zipline kit does not come with this component, because it is unnecessary considering the length of the ride, and how low to the ground you will probably be. There are certain risks you must assume for anyone who climbs in, and that could include guests some of the time. Try to stay from crazy stunts like dropping off the seat in the middle of your pool, because there is no telling you will drop before crossing it completely. And if you damage the product doing something like this, you have voided your warranty coverage.
Install the zipline kit according to safety regulations, and use it likewise. The safeties are set up for your own benefit. There is no fun in serious injury, and that is possible from something as simple as a mistimed release. You might do something that ends up getting the activity banned in homes. Put a lid on the impulses when you climb on, and just enjoy the speed of zipping through the air with your legs dangling.
