3. Insert a conical half-way into a main tube and check that the drillings in the conical are aligned with
the drillings in the main tube. The larger hole in the conical must face outwards.
4. Insert now a truss pin with the narrow side down and push it through. For a tolerance free connection,
use a copper or synthetic hammer to drive the pin completely through the cone and main tube.
5. Push a safety clip through the small hole of the truss pin. This secures the pin so that it cannot fall out.
6. Repeat this step for each main tube. You might have to turn the truss to insert all truss pins and safety
clips.
7. Insert now the truss with the conical side into the next truss you want to add and secure the main tu
bes of the second truss as well with all truss pins and safety clips.
If you are using a screwed GLOBAL TRUSS system (e.g. M25AS) then you can use the same methods as
described above. Make sure the nut is fixed on the screw, but not too tight, as it may damage your truss.
1.2 DISMANTLING
1. Remove all the safety clips
2. Push truss pins from the inside to the outside and remove them (If you use a synthetic or copper ham
mer to drive the pin out, be careful as the truss pin might fly off when you knock hard with the ham
mer)
3. Loosen the connection and pull the truss apart
4. Collect and secure all conical, truss pins and safety clips.
1.3 INSTALLATION
Please consider the DIN 15560 and the respective national norms during the installation.
• When rigging, dismantling, or servicing in an area where installation exists, always be sure that the
ground surface is safe, stable, and not dangerous.
• The installation must always be secured with a secondary safety attachment, e.g. an appropriate catch
net. This secondary system must be constructed in such a way that no part of the primary installation
can fall down in the unlikely event that a portion of the primary system fails.
• The installation of the trussing has to be built and constructed in a way that it can hold 10 times the
weight for one hour without any harming deformation.
• Security and mechanical technological facilities must be checked by an expert as follows:
- at least once a year
- before first start-up and after substantial modifications before the restarting operation
- every four years to the extent of the acceptance checking
Qualified personnel must make sure that these checks are carried out as specified!
