8.6.5
Wire mesh: replacing a length of mesh
a)
Cut open the wire binders of the damaged length of mesh and remove the length of mesh.
b)
Restore the geometric state of the barrier by e.g. tightening ropes, replacing U-brakes, etc.
c)
Using wire binders, fasten the new length of mesh to the main net in accordance with the product manual.
8.7
Repairing ropes
As a basic principle, ropes are replaced rather than repaired.
8.8
Replacing ropes
Ropes must be replaced if the rope is damaged according to section 4.5. Often, only the elongated U-brakes need
to be replaced.
Depending on the situation, replacement is done in accordance with sections 8.2 / 8.3 / 8.4.
The required tightening torques are listed in section 7.
8.9
Replacing posts
8.9.1
Replacing middle posts
In most cases, the middle post can be replaced without dismantling the net or the ropes.
d)
Secure the faulty post with auxiliary ropes.
e)
Dismount the shackle with the running wheel on the post head.
f)
Remove the hinge bolt of the post.
g)
Lift the post out of the base plate using a winch, and place it, secured, on the ground on the mountain side.
h)
Transfer the retaining ropes from the faulty post to the new post.
i)
Place the post foot into the base plate and fit the hinge bolt.
j)
Erect the post in a secured manner.
k)
Refit the running wheel to the post head.
l)
Remove the securing ropes.
8.9.2
Replacing edge posts
The lateral ropes brace the entire barrier via the edge posts on the slope. It is therefore essential to loosen the
lateral ropes when replacing an edge post. Depending on the situation, the subsequent middle posts can be used
to perform the function of the edge posts during repairs. In this case, the middle post is secured on the valley side
and the lateral ropes are fixed to the middle post using suitable equipment. The edge post is then replaced as
described in section 8.9.1. If this is not possible, a certain number of fields or the entire barrier must first be laid
securely facing up the mountain until the edge post can be replaced.
