TIGHTENING YOUR ZIPLINE
Using the turnbuckle to tighten - Inspect your initial installation work carefully and thoroughly. The zipline cable can hold weight
many times that of most riders. The loops, u-clamps and attachment trees are the most likely to fail, if not assembled correctly,
and therefore should be inspected extra carefully and often.
•
Tune the zipline by tightening turnbuckle, by twisting
the center section of it.
•
Tighten the line until it “appears” to be nearly
level or
straight. DO NOT OVERTIGHTEN.
•
You can now remove your six small nails used
to hold
the cables in position during installation.

MANDATORY TESTING YOUR ZIPLINE INSTALLTION
When your course setup is complete and
before a rider takes the first ride you must
perform two important tests.
A
- Load Stress test
B
- Course speed test
A - Load Stress Test
Test your installation at 5ft (152cm) from each end
of the cable, one of two ways.
•
Either suspend 250lbs (113kg) from the rope attached
to the trolley OR
•
Throw a rope over the cable and have a 250 LBS (113 kg)
person lift their weight off the ground.
•
Note: Look and listen for any issues. This will ensure that
the attachment structure and cabling is stable and secure.
•
DO NOT EXCEED 250 LBS (113 kg) for the test.
B-Course Speed Test
The test weight should never hit the Finish Point U-clamps!
With the 250 lbs (113kg) weight attached to the trolley,
launch the trolley down the course. The test weight
should slow down past the midpoint as the sag or
dipping in the cable comes into play. It should continue
to slow down and come to a gentle stop just short of the
first U-clamp. If the test weight hits the U-clamp, simply
adjust the cable tension (loosen the turnbuckle) or if more
speed reduction is required, adjust attachment
heights:
Raise Finish Point or lower Start Point. BE SAFE, NOT FAST!
REPEAT TEST 5 TIMES! This test helps stretch out cable.
Note: Weight should not drag on the ground during the test.
