Two-stage swing-away lattice extension 3.6 Description of rigging work
Connections in the front area Connection between 9 m (30 ft) section and 12.5 m (41 ft) section The connection must be made: – or transportation, – for installation and removal, – when unrigging the 22 m (72 ft) two-stage swing-away lattice extension. The connection must be disconnected: – when rigging the 13 m (43 ft) swing-away lattice extension, – when rigging the 22 m (72 ft) two-stage swing-away lattice extension.
Disconnecting connection
• Swing the catch hook (3) out of the bracket (1) into position A.
• When rigging the 13 m (43 ft) swing-away lattice extension, swing the 12.5 m (41 ft) section in front of the main boom. Then swing the catch hook back to the attachment point (4) in position B.
• When rigging the 22 m (72 ft) two-stage swing-away lattice extension, swing the 9 m (30 ft) section away from the 12.5 m (41 ft) section a little and then move the catch hook back to the attachment point (4) in position B. Making connection
• Check if the catch hook is in position B. • When unrigging the 13 m (43 ft) swing-away lattice extension, swing the 12.5 m (41 ft) section gently onto the 9 m (30 ft) section – the catch hook (3) latches behind the bracket (1).
