Ziplines are fun, and children love a zipline ride. The good news is that you can build a zip line in your house easily within a few days. Undoubtedly, it’s a cool way to make your backyard more appealing for the kids.
If you often host parties for your children in your garden or backyard, their friends will be delighted to visit your home. However, you must follow several safety measures and keep the zipline low.
But what if your backyard has no tall or strong trees? Don’t worry. You can still build a zipline by following a few easy steps. Just make sure you have all the good quality materials.
Read this post to learn how you can build a zipline without trees.
Things You’ll Need To Build a Zipline
Before you get started, you need several items to build a strong and secure zipline. You must ensure the quality of these items as safety is a priority. Here’s a list of some main items you may need:
Anchors are the first things you need. When installing a zip line anchor, you must remember a few important details. This is crucial since most individuals misjudge the amount of horizontal force applied during a zip line trip. Typically, it might cost you approximately 3,000 pounds.
Wood or Metal Posts
You must get metal or wood posts that measure at least 12’’ in diameter. That is surely a thick post, but it’s important for the safety of your children.
In addition, when you install these posts, you must ensure that they are sunken at least 4 feet deep into the ground. However, you can also sink 10% of the length of your pole with an additional 2 feet.
You have to secure the poles with a thick layer of concrete that’s at least 6 inches in thickness.
However, if your backyard has special soil conditions such as loose rocks, sand, or water, you must not risk building a zip line yourself. Instead, consult a professional engineer to get the job done.
Guy Cables and Ground Anchors
Now you might be wondering what a guy cable is. It is known by several other names such as guy-line, guy-wire, or guy-rope. It’s a cable that’s been tensioned to provide maximum stability in the zip line pole.
In addition, it may help reduce the tension of your backyard zip line since the weight will be applied horizontally. These guy cables must be installed at an equal distance or greater than your attachment height. For instance, if the height of your wooden pole is 15 feet, you must install the cables at a 15 feet distance.
Steps to Build a Backyard Zipline without Trees
If you’re ready to build a zip line and have all the necessary requirements, you can start following these steps. However, it is recommended that you check all safety measures and get your plan verified by a professional since it can impose serious safety risks.
Once done, you can start building the project by following these steps:
Choose a Spot
The first step is to determine the span of your zipline. For this, you need to measure the area. In addition, you must choose a safe area to install the metal or wood poles. Make sure the spots are free from damage and are not affected by water or sand as it may weaken the zipline.
Moreover, you must check if the zip line will cross any obstacles such as a backyard house, furniture, etc. If the area is clear, you can move to the next steps.
Install the Poles
Now, you can install metal or wooden poles. Make sure you have got the best quality poles. In addition, they must be thick and robust. If a strong tree is present nearby, it can help as well. But make sure you check the tree for unsafe or rotten branches.
Moreover, install the posts at an average distance of 50 to 500 feet or 15.2 to 152.4 meters.
Stretch the Cable
Depending on your zip line area, you need to get enough cable. Make sure the zipline has a belly between two points. In addition, you must measure the zipline from the starting pole.
Moreover, you should remember that you do not stretch out the cable tightly as it can cause serious trouble. Because a tight zipline will make your kids slide at fast speeds. As a result, they may crash when they reach the end.
Attach the Cable
If you were to use a tree for a zipline, you could have wrapped the cable around the branch several times. This would have provided maximum safety. However, since you do not have a tree in your backyard, you can clamp your cable to the poles. Attach the cable to one pole.
Once it is secured, you can move toward the next pole. In addition, you must ensure to use the best quality clamps. They must be suitable for the size of your cable’s diameter accurately.
After clamping the cable around the pole, you may tighten the clamps with the help of a socket set.
For example, you may place two clamps at a distance of six inches. Moreover, use 3 – 4 clamps on each pole for added safety. After finishing the process with one pole, you can clamp the cable on the next pole, tighten it, and raise it from the ground.
Use Temporary Cable Clamps
This step includes attaching a temporary cable clip for building your backyard zipline. You need to attach a winch to your cable clamp before attaching it to your poles. It may measure around 20 feet or 6.1 m from the end.
Once done, you can winch your cable up and then wrap the cable’s free end around the pole. Then, clamp the other leading end to set it.
In addition, you must place the clamps at a distance of 8 feet from the pole. This may let you remove the winch from the first clamp. You can repurpose it and place the wench on the permanent cable clamp present at the farthest end.
This step is important as it lets you make other vital adjustments to your cable. For instance, if you find your cable stretching too low, you can tighten it up with the winch.
Once you are satisfied with the resistance structure of your zipline, you may add the other accessories. For instance, some people may use a simple rope to tie themselves, while some may add support to stand up or sit.
Once your zipline is ready, you must check it several times while wearing safety gear before letting your kids use it.
Building a zipline in your background is not too challenging. However, you need to keep several safety measures in check. You must use all high-quality materials, but it is better if you get assistance from a qualified professional since the job can be risky.
Once you’ve completed the project, you must test it yourself before allowing your kids to use it.
Lastly, it would be best to not raise your zip line too high since a DIY project can have flaws. Therefore, you must keep your zip line within a low range.
