3.4.9 Swinging the swing-away lattice towards the main boom head
This section describes the slewing of the swing-away lattice
– Onto the main boom head when rigging
– Onto the main boom when unrigging
Prerequisites – The swing-away lattice is in transport position with the swing-away lattice
folded on the side;
à p. 3 - 30.
– The connection in the
Front area has been established; à p. 3 - 38.
–In the
Rear area, either the connection between section 2 and the main
boom or between section 1 and section 2 has been undone, depending on
the swing-away lattice required;
à p. 3 - 45.
– The connection in the
Middle area is in the position required for the nec-
essary swing-away lattice;
à p. 3 - 42.
Swinging the
lattice extension
Only swing the swing-away lattice once all of the mentioned prerequisites
have been fulfilled.
When swinging, the swing-away lattice rolls onto the run-up rail, turns
around the slewing axis (2) in the
Front area and makes contact at the con-
necting points (1) at the front.
• When rigging, pull the swing-away lattice away from the main boom at
the back until it makes contact at the front and the connecting points (1)
are in line.
• When unrigging, push the swing-away lattice on the run-up rail onto the
main boom at the rear until it engages on the slewing axis, and insert the
pin;
à Establishing the connection, p. 3 - 38.
G
Risk of accidents due to falling swing-away lattice
Make sure the connection in the
Front area has been established before you
swing the lattice extension towards the main boom head.
This will prevent the swing-away lattice from falling down during swivel-
ling and causing injury to you or other persons.
