10.3.3 Lifting capacities and slewing ranges for outrigger spans
without separate lifting capacity tables
In the case of outrigger spans where the opposing outrigger beams at the
right and left sides are extended to different lengths,
lifting capacity tables are
only available for combinations where the outrigger span at the right side is
greater than at the left side. This applies to two types of outrigger spans.
Outrigger span type
Three / One
Lifting capacity tables are only provided for the combination
One outrigger
beam retracted – left
, e.g. for the outrigger span (I).
Outrigger span type
Right / left
Lifting capacity tables are only provided for the combination
Right greater
than left
, e.g. for the outrigger span (II).
When the truck crane is on outrigger beams with a mirrored outrigger span
then the same lifting capacities are enabled in the correspondingly mirrored
slewing range.
Example
Assuming that the truck crane is on outrigger
beams with the outrigger span (III) and a load is
to be lifted in the slewing range To the right (1).
Since the outrigger span at the left side is greater
than at the right side, the lifting capacity table for
the mirrored outrigger span (II) with the mirrored
slewing range To th e left (2) must be used.
The loads specified for the slewing range (2) are
enabled in the slewing range (1) for the outrigger
span (
III).
