Step 1. Determine the END height for Slider Line
•
Line should be set so that the fully extended seat hangs about 24 inches from the ground with the
lightest rider sitting on the swing.
•
Add the values below to determine the End height:
o
7’
for the fully extended swing length.
o
2
’
clearance below the swing.
o
Use the chart below to estimate the amount of sag for the smallest rider.
o
For example, you determine the sag to be about 1 foot (50 pound rider with trees 50 feet
apart), add
7’ and
2
’
; height of the End should be 1
0’
(1
’
+
7’
+ 2
’
= 10
’
) above the ground.
•
As shown in the chart below, the farther apart the anchor trees are, the more the slider line will sag.
This is normal, but should be taken into account when setting the line height. Also shown in the
chart, heavier riders will experience more sag.
•
To accommodate larger or heavier users, simply shorten the length of the swing ropes.
•
The End height may be adjusted for best rider experience. The calculation is a starting point. Adjust
to a height you feel is safe for your riders and your situation.
Step 2. Determine START height for Slider Line
•
Multiply the distance between trees by 0.03, and add this amount to the End height you calculated.
o
For example, distance between trees is 50 feet, so multiply 50 x 0.03 = 1.5 feet. Now add the
End height, 1.5 + 10 = 11.5 feet. Start height should be 11.5 feet above the ground.
•
Slider Line must never exceed 3% slope (3 feet drop per 100 feet of distance). High speed collision
with End point may cause injuries or death. Be safe, go slow.
•
If ground is not level, measure and account for elevation change. Subtract height from Start height.
