Installation Tolerances
The
Sentry Barrier TL-4 ThrieBeam System
is an engineered safety device. To obtain optimal
performance is it important to install all components of the system to within the allowable tolerances
stated below (also in
Appendix C
). Particular care must be taken to ensure;
•
Suitable horizontal alignment and verticality of the line posts.
•
Consistency in the vertical height of the line posts.
•
Orientation and height of the terminal end or crash cushion.
Sentry Barrier TL-4 ThrieBeam System
has to be installed at 1040mm to the top of the post. A
vertical height tolerance of ±25mm is acceptable for both the
Sentry Barrier Post TL-4
. The top of
the ThrieBeam is to be positioned 10mm above the top of the
Sentry Barrier Post TL-4
with a
tolerance of ±5mm. The
Sentry Barrier Post TL-4
laterally is constrained to ±15mm tolerance. It is
of upmost importance for these tolerances to be adhered to in order to ensure safe function of the
Sentry Barrier TL-4 ThrieBeam System
.
