TMS800E13 OPERATOR MANUAL OPERATING CONTROLS AND PROCEDURES
3
Published 02-06-2014, Control # 495-00
The air suspension system must be deflated when
on outriggers.
The outrigger control switches are located on the outrigger
control box located in a pocket at the front of the
superstructure cab. In addition, the outriggers may be
operated from optional control boxes mounted on both sides
of the carrier just forward of the front outriggers. When using
the optional control boxes, the engine speed is increased
due to a signal to the engine ECM when the Extend/Retract
Switch is placed in either position.
1. If outrigger floats are not already installed, remove them
from float stowage locations on left, right, and rear of
carrier frame. Secure the floats to the rods of the
outrigger jack cylinders (aka outrigger stabilizer
cylinders) using the levers on each float.
2. Depress the appropriate Outrigger Selector switch to
EXTENSION and then position the Outrigger Extension/
Retraction switch to EXTEND. The outrigger beam
should begin to extend. Refer to
Engaging the Mid
Extend Lock Pin , page 3-48 if the crane is to be operated
at the mid-extend position.
NOTE: More than one outrigger may be extended at one
time. However, each Outrigger Selector switch
should be depressed individually and the outrigger
extension/retraction switch momentarily positioned
to EXTEND to ensure that each outrigger is fully
extended.
For cranes equipped with an Outrigger Monitoring
System, outrigger positions are automatically
monitored through the RCL. Refer to
Outrigger
Monitoring System (OMS) (Optional—Standard in
North America)
, page 3-48.
3. After all four outrigger beams have been extended,
depress the appropriate Outrigger Selector switch to
STABILIZER and position the Outrigger Extension/
Retraction switch to EXTEND.
4. Extend each stabilizer, until the floats touch the ground.
NOTE: More than one stabilizer may be extended at one
time.
5. After all floats are on the ground, extend the front
stabilizers about 8 to 10 cm (3 to 4 inches) and then
extend the back stabilizers the same distance. Repeat
until all tires are off the ground.
6. Repeat step 5 until all wheels are clear of the ground
and the crane is level as indicated by the sight level
bubble located on the right side of the cab or in each
carrier outrigger control panel. If it is suspected that the
bubble level indicator is out of adjustment, verify and
adjust the bubble level as described in
Bubble Level
Adjustment , page 3-47:
Proper Leveling of the Crane
ASME B30.5 specifies that if a crane is not level within 1% of
grade, the allowable capacities must 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 3-
46.
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, relevel the crane using the
procedures under
Setting the Outriggers , page 3-46.
Bubble Level Adjustment
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.
CAUTION
Depress outrigger selector switch before the outrigger
extension/retraction switch. Failure to do so may cause a
hydraulic lock against the individual solenoid valves, and
keep them from opening.
DANGER
All four outrigger beams must be equally extended to the
mid position vertical stripe or fully extended position
before beginning operation.
DANGER
All four outrigger beam lock pins must be engaged before
operating from the mid-extend position.
For cranes not equipped with an Outrigger Monitoring
System, the operator must select the proper load chart
and RCL program for the outrigger position selected.
