3.4.1 Securing the swing-away lattice with a rope
If the truck crane is aligned unfavourably, the swing-away lattice can swivel
around independently when you undo the last connection to the main
boom.
Secure the swing-away lattice in the following
manner:
• Attach a rope (2) to the front of the swing-
away lattice.
• Guide the rope underneath the swing-away
lattice, over the rope guide (1) on the main
boom and back again.
• Have a helper hold the rope tight while you
undo the last connection.
H
If you are alone, fasten the other end of the rope to the crane (depending on
the slewing direction of the superstructure, e.g. to the outrigger beam on
the rear right or to the steps of the access ladder to the carrier on the left).
G
Risk of accidents due to the swing-away lattice swinging of its own accord
Secure the swing-away lattice on the main boom always with a guide rope
before undoing any connections.
This will prevent the swing-away lattice from swinging around of its own
accord and pushing you off the carrier or injuring other persons in the slew-
ing range.
