3.4.7 Connections with folded swing-away lattice
If the swing-away lattice is swivelled to the main boom, there are areas on
the main boom where various connections must be loosely established dur-
ing rigging:
Depending on the rigging mode and job, different sections of the swing-
away lattice have to be connected one below the other or to the main boom
basic section.
Connections in the
front area
There is a connection between section 1 and the main boom in the
Front
area.
This connection must be established if the lattice extension is folded on the
side of the main boom during unrigging or the installation.
The connection must be undone if the lattice extension is rigged or
removed.
The connection consists of the pin (3), the slewing axis (1) on the basic sec-
tion and the holder (2) on section 1.

Risk of accidents due to falling parts
Secure the pins both in the bearing points and the holders always with
retaining pins to prevent unsecured pins from coming loose, falling down
and causing injuries.
