3.5.6 Notes on main boom operation with the folded / rigged swing-
away lattice
Folded This section applies to instances when the swing-away lattice is folded on
the side.
If an swing-away lattice is folded on the side when operating with the main
boom, the loads specified in the
Lifting capacity tables are reduced.
The relevant formulas and examples used to calculate these values during
operations planning can be found in the
Lifting capacity table.
The reduced values are displayed directly on the
SLI insert on the Maximum
load
display (1).
Rigged This section applies when the swing-away lattice is rigged and pinned to the
main boom head.
For main boom operation with a rigged swing-away lattice, you must enter
the current rigging mode for the main boom without a swing-away lattice
on the SLI.
The values specified in the corresponding
Lifting capacity table for the lifting
capacities and for the permissible wind speeds are reduced in this case.
S
Risk of overturning in impermissible rigging mode
Main boom operation with a rigged swing-away lattice is only permissible
in rigging modes that are also permissible for the rigged swing-away lattice
(outrigger span, counterweight, slewing range).
If you establish rigging modes that only apply to main boom operation
without a rigged swing-away lattice (e.g.
Free on wheels working position),
the truck crane could overturn during operation.
