Two-stage swing-away lattice extension 3.6 Description of rigging work
Connections on lattice extension
The two parts of the lattice extension are connected at the pivot point of the two-stage swing-away lattice extension.
The connection must be made: – for transportation, – for installation and removal, – when unrigging the 13 m (43 ft) swing-away lattice extension, – when rigging the 22 m (72 ft) two-stage swing-away lattice extension. The connection must be disconnected: – for rigging the 13 m (43 ft) swing-away lattice extension, – when only the 12.5 m (41 ft) section needs to be folded on the side of the main boom for transportation.
G
Risk of accidents from the 12.5 m (41 ft) section slipping! If you have disconnected the connection when rigging the 13 m (43 ft) swing-away lattice extension, make sure you re-establish the connection during unrigging. Only then is the 12.5 m (41 ft) section secured against slipping. This prevents the 12.5 m (41 ft) section slipping or falling off during transportation or main boom operation. Making connection
• Remove the retaining pin, take the swivel pin out of the holder (3) and insert it in the bearing point (2) for swinging.
• Remove the retaining pin, take a securing pin out of the retaining sheet (4) and insert it in the bearing point (1) for swinging and operation.
