UNATTENDED CRANE
The configuration in which the crane should be left while
unattended shall be determined by a qualified, designated
individual familiar with the job site, configuration, conditions,
and limitations.
SUPERSTRUCTURE CAB PLATFORM
To pull out the cab platform, pull a retaining pin (1,
Figure 4-27) out on one end of the platform while pulling on
the lip of the platform. Do the same on the other end of the
platform. Now use both hands to fully pull out the platform.
PROPER LEVELING OF THE CRANE
The load capacity chart developed in accordance with ASME
B30.5 is based upon the crane being level to within 1% of
grade. If the crane is not level to 1% of grade, the capacity
will be reduced. Therefore, whether lifting on rubber or
outriggers, it is essential that the crane is level to within 1%
of grade. The bubble level that is provided on the crane is
calibrated to be accurate within 1% of grade.
To properly level the crane, the boom must be positioned
over the front of the crane, fully lowered to horizontal and
fully retracted (for cranes fitted with a boom rest, the boom
shall be stowed onto the rest). Raise and level the crane
using the outriggers; refer to Setting the Outriggers, page 4-
34.
A working crane may settle during lifting operations.
Frequently check the crane for level. When rechecking the
crane for level, the boom must be positioned over the front of
the crane, fully lowered to horizontal and fully retracted (for
cranes fitted with a boom rest, the boom shall be stowed
onto the rest). If necessary, re-level the crane using the
procedures under Setting the Outriggers, page 4-34.
Bubble Level Adjustment
NOTE: To check and adjust Auto level refer to the Service
Manual.
The bubble level adjustment should be checked periodically;
if it is suspected that the bubble level indicator is out of
adjustment, verify and adjust the bubble level as follows:
1. Position the crane on a firm, level surface.
2. Extend and set the outriggers. Level the crane, as
indicated by the bubble level indicator, using the
outriggers.
3. Place a miracle pointer level, carpenter level, or similar
type device on a machined surface such as the turntable
bearing or bearing mounting surfaces.
4. Using the outriggers, level the crane as indicated on the
leveling device used in step 3.
5. Using the bubble level indicator mounting screws, adjust
the bubble level indicator to show level.
USING THE OUTRIGGERS
Besides the remote control and superstructure cab the
carrier is equipped with remote mounted outrigger panels on
each side of the carrier to allow the outriggers to be operated
from the ground.
Setting the Outriggers
NOTE: The two ground outrigger control panels only
operate when the carrier ignition is on, the parking
brake is set. The operator can only operate the
outrigger beams on the side he is operating from.
The jacks can be operated from either side.
Make sure the air suspension is deflated before raising
machine on outriggers.
WARNING
Tipping Hazard!
Changing weather conditions including but not limited to:
wind, ice accumulation, precipitation, flooding, lightning,
etc. should be considered when determining the location
and configuration of a crane when it is to be left
unattended.
Failure to comply with these instructions may cause death
or serious injury.
WARNING
The outriggers and the center front jack must be properly
extended and set before any other operation of the crane
is attempted.
The center front jack will retract when the main outrigger
control is shifted to the retract position. After operating the
main outrigger control, the center front jack must be reset
before operating the crane.
