Important:
Completely review the manufacturer ’ s manual included with the
CASS
®
S3 tensioning meter prior to tensioning of the cable.
Important:
Ensure that the tension meter is set for pre-stretched cable.
Important: Completely r
eview the infrared thermometer manufacturer’s
manual prior to tensioning of the cable.
Warning: Infrared light is harmful if shined into the eyes.
Warning: Read and understand the directions provided for the CASS
®
cable
pulling tool.
Warning: Extreme care should be taken to ensure that the CASS
®
cable
pulling tool is attached to the cable in such a location that if it slips, the chain or
CASS
®
cable pulling tool will not hit anyone. It is suggested that the pulling
equipment be placed between the workers and the CASS
®
cable pulling tool.
Read the directions and ensure the tool is clean, dry and not worn.
Complete the following steps to tension the cables:
1. Check the cable run to see if any of the turnbuckles or torpedo cable splice will pass from
one side of the post to the other during the tensioning process. If they will, pull the post
for the tensioning process. Also check the fitting marks at each turnbuckle to make sure
no marks are showing.
2. The tensioning of the cable will be taken at a location no closer than 500’ [167 m] from the
end that has not been connected to the CCT or Anchor Cables. It is recommended that
cable tension readings be taken in tangential sections.
3. For cable runs greater than 5,000’ [1,525 m], the cable should be pulled every 3,000’ [915
m] to remove the slack from the cable.
4. With the required tension on the cable, place a mark on the cable where it meets the
threaded end of the CCT.
5. Release the tension on the cable. Go back approximately 28” [0.71 m] from the mark and
cut the cable.
6. Place a right-hand field applied fitting using the procedures in the Field Applied Fittings
with a Turnbuckle section.
7. On the CCT end, place a turnbuckle (PN-5826G for 1” fitting; PN-5711G for 3/4” fitting) on
the fitting by only a couple of threads. Pull the cable until the cables are connected to the
turnbuckle. With both fittings inserted in the turnbuckle, the turnbuckle will be turned until
the 1 1/2” [38 mm] marks on the cables ends of both threaded rods are in the turnbuckle.
