GRP ladder and tray
| 249
3
Fix the ladder at each support with
2 hold-down clamps UL KS and 2
M1030/V4A bolts.
4
Follow the installation procedure.
A All fittings must be supported at every cable entry.
B Add a central support for all fittings with radius greater than 250mm
and/or with width greater than 400mm.
C Lock systematically each splice plate UL IH with 4 M620/V4AS bolts
on fittings extremities.
5
Fix the cover with clips made of stainless steel 316 (ref.DF50, DF80,
DF100 and DF150).
Under normal conditions use 3 clips alternatively on each side per 3
metres of ladders.
Under extreme conditions (strong winds > 60km/h) use 7 clips per 3
metres of ladders.

1
Place the end of the ladder
about L/5 away from the
supporting bracket.
L/5 corresponds to the ideal
place for mechanical stability:
place the junction between
2 ladders at this point.
2
Connect the ladders together.
Place the side-rails facing each
other.
Fix the stainless steel splice plates
UL IH with the help of stall clips,
the oval holes* placed nearest the
supporting bracket.
Lock the junction with 4 x M620/V4AS bolts.
(*) The splice plates UL IH are pre-punched with 2 holes Ø 8mm and 2 oval
holes 20 x 8mm in order to assure a solid fixing and to allow the expansion
of the GRP material.
