How do you make a zipline?

Answer 1

CAUTION: Zip lines are dangerous. Make sure you know what you are doing before attempting this.

1) The most important part is selecting the right trees (assumes you will install between two trees):

• Select healthy trees at least 18" in diameter at the cable connection point. Recommend you check with an arborist (tree expert) before starting your zip line project.

• Ensure area between trees is clear at least six feet on each side of zip line path and at least two feet above the cable. If there are branches from other trees extending into the area, then you need to trim the branches.

• Ensure there are no electric lines or any kind of overhead lines above the zip line path.

2) Select your components:

• Use 1/4" or 3/8" 7x19 Stainless Steel Aircraft Cable (type 304 or 319). Ensure you know how to attach cable clamps. If not, find out so you do not hurt someone.

• Connect your zipline to trees using heavy-duty galvanize eye bolts (not the kind you will find in a typical hardware store).

• Use a professional traverse pully on top of the cable.

3) Attach to the trees:

• Drill a hole through the tree at the height you would like for your zipline.

• Put the eye-bolt through the tree.

• Attach your cable.

• Add the pully and whatever you would like to hang onto under the pully.

4) Enjoy! [But, be safe.]
