Installation Instructions for mounting spring hanger
1 Fit the Spring Hanger to the ‘U’ clamp already fitted to both side of the bustrunking (Rising Mains)..
2 Remove nut A from Rigid hanger assembly, and pass the M16 bolt thru the holes in the ‘C’ channel already grouted
on the floor/wall
3 By virtue of bustrunking weight the spring will compress and creates a gap between nut ‘C’ and L support. Tighten nut
‘C’ by hand so as to eliminate the gap.
4 Adjust nut B on both sides of bustrunking until it reaches desired level for fixing joint with lower bustrunking. Ensure
that nut B is adjusted equally on both sides to install bustrunking vertically straight.
5 Lock nut A from lower end of bolt to the ‘C’ channel.
6 Repeat step #1,2,3,4,5 for subsequent bustrunking.
7. Loosen nut C to allow enough gap for spring to expand under thermal conditions after complete installation.
