38 User Manual Compact Crane C10
6.5 Setting the outriggers
WARNING!
To prevent contact between the ballast and outrigger legs during
slewing make sure that the outrigger legs are not extended too far, e.g.
one outrigger placed on an elevation.
WARNING!
Ensure that the outrigger leg is horizontal, with a maximum deviation
of 5°, to prevent instability.
WARNING!
Do not raise the compact crane higher on the outriggers than
necessary; once the tracks have been lifted off the ground it is high
enough.
WARNING!
Assess the ground condition and use outrigger pads to reduce the
ground pressure.
CAUTION!
Make sure the outrigger foot sits in the recessed circle on the outrigger
pad when setting the outriggers. This is particularly important when
raising the machine high on the outriggers, in connection with the
folding legs.
CAUTION!
Check that the crane is retracted.
6.5.1 Order of operations
DANGER!
Outriggers may only be used on a suitable surface. This means
adequately level and with sufficient load bearing capacity.
WARNING!
Maintain a close watch on the active outrigger leg during extension
to prevent foot entrapment.
Preparation
Make sure the ground has sufficient load bearing capacity.
Position the machine in the ideal location; consider safety, obstacles in slewing
range, outreach of the load and capacity and limits of the crane and ground.
If the crane is raised on the outriggers in the vicinity of a ditch or slope, it is
recommended that distance A from the outrigger to the edge be at least twice
as long as depth B of the ditch (see figure 40).
Make sure that people who must be within the working area of the crane can
work there safely, by giving them instructions and showing them safe escape
routes.
To operate the outriggers, the boom angle must be less than 40 degrees and
the ballast must be retracted.
