T-Top
For the BG800 Gate and the Minimum
Deflection BG800 installations, a T-top section is
attached to the top face of the BG800. The T-top
comes in 6m long sections as standard and the
lifting points for the T-top only are shown below.
A minimum of two lifting points must be used
for lifting. The angle between the two chains
should never be more than 120 degrees.
Note: Do not use the T-Top lifting points to lift the
BG800 sections.
The T-top is simply lowered on to the top of the
barrier and aligned with one 6m half section of
barrier and then locked down using two bolts
per 6m length secured into special nut attached
to them.
The special nut is passed
through the relevant slot
in the top of the barrier
and then turned 90° to
lock it into the slot to allow
the bolt to be tightened
down to secure the T-top.
One section of T-top is
then attached to the next
by use of two splice plates
either
side,
fastened with six
standard
M16
BG800 bolts per
splice plate.
At the beginning
and end of a T-
top installation a
ramped
transition
section must be installed, this is simply placed
on top of the BG800 adjacent to the first or last
section of required length of T-top and
connected using the splice connection, to bolt it
to the T-top.
Note: There are T-top sections available for the
0.61m radius units also.
