Two-stage swing-away lattice extension 3.6 Description of rigging work
Connections in the middle area In the middle area, on the run-up rail, there is a bearing point between the 12.5 m (41 ft) section and the main boom. The connection must be made when only the 12.5 m (41 ft) section is folded at the side of the main boom. The connection must be disconnected when the lattice extension needs to be rigged again from this state.
Making connection
• Swing the 12.5 m (41 ft) section on the runup rail fully onto the main boom.
• Remove the pin (1) from the holder (2) and attach the 12.5 m (41 ft) section to the main boom with the pin.
• Secure the pin with the retaining pin.
Disconnecting connection
• Remove the pin (1) from the connection and insert it in the holder (2).
