Back-ups are absolutely necessary for ropes course belay
cable bolted terminations. Most of the through bolts
are buried in the pole or tree and inaccessible for inspection.
Because of this, a separate cable must be used as a back
up for the through bolt. There are several different
ways to attach a back up that are acceptable. The
drawing above shows the most common method. Refer
to the ACCT standards manual for alternate back up methods. |
| Depending
on the specific procedures for static belay ropes courses,
back ups may be required on all cable terminations. It
is recommended that clear PVC tubing be placed around
the back up cable to protect it from damage due to exposure
from chemicals used for treating poles. |
| When
using a Thimble Eye bolt, the cable can be attached without
a thimble eye. A thimble eye is necessary for terminations
to a nut eye or oval eye bolts. A minimum of two cable
clamps or fist grip clamps is required for the termination
of the belay cable. Two clamps are also required for each
end of the back up cable termination. |
| Refer
to the cable
clamp installation page for proper installation
procedures and spacing. If the through bolt shows
any deformation, rust or bending, it should be replaced.
Please refer to the ACCT standards for specific
requirements. |
