X-TENSION 350 Median Maintenance (Traffic Face Impacts)
Types of repair are divided into two categories:
Traffic Face Impacts and Head on Impacts (Next Page)
Traffic Face Impacts
Key Repair Steps:
1. Remove cables
2. Remove damaged rail
3. Remove components from rails
4. Remove damaged posts
5. Assess damage
6. Reassemble
Step 1: Remove Cables
Undo nuts at downstream cable bracket (post 7). Take out the bolts on the side of the impact
head that hold the friction plate in place and rotate the locking bar backwards.
Pull one cable at a time from the front side of the impact head and completely remove them.
Rotating the cables as you pull them will help. Undo nuts at ground anchor end and remove
cables.
Step 2: Remove Rails
Unbolt the splice bolts first. Then unbolt the post bolts and lower rails to ground.
Step 3: Remove X-TENSION 350 Median Components
All the X-TENSION 350 Median components are attached to the rails with standard splice
bolts. Unbolt and remove the components.
Step 4: Remove Posts
Undo the bolt at the bottom of Post 1 and pull out post. For all other damaged line posts,
attach a chain to the top half of the post and pull out of the ground with either a crane truck or
digger.
Step 5: Assess the Damage
Any part that cannot be reused must be replaced with a new part. Always replace the yellow
shear bolts. Cables can be reused. Generally, all the specialised components of the system
such as the head and brackets should be undamaged.
Step 6: Reassemble
Reassemble as per system installation instructions.
