Mounting the threaded rods to the U profiles
NOTE:
It is possible to pre-assemble one end of the threaded rods on the device.
This makes subsequent mounting on the mast easier and increases safety
because fewer loose parts need to be carried and mounted.
Fig. 13: Pre-assembly of threaded rod on U profile
1. Screw a hexagon nut approximately 5 cm onto the threaded rod.
2. Feed the end of the threaded rod with the pre-assembled hexagon nut
through the appropriate hole on the inner side of the U profile and secure
the threaded rod using a hexagon nut on the outer side.
3. Tighten the hexagon nut.
4. Repeat for all threaded rods.
