Crane Functions - Manitowoc Grove RT540E Operator's Manual

OPERATING CONTROLS AND PROCEDURES
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 The crane also allows
operations with the outriggers fully retracted., page 3-21.
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 The crane also allows operations with the
outriggers fully retracted., page 3-21.
Level Indicator Adjustment
The Level Indicator should be checked periodically; if it is
suspected that the Level Indicator is out of adjustment, verify
and adjust the 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 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 level indicator mounting screws, adjust the
level indicator to show level.

Crane Functions

Using the Outriggers
The outriggers are operated from the front console in the
cab, or by using the jog dial on the armrest.
To prevent serious injury or death, keep clear of moving
outrigger beams/jacks.
Death or serious injury could result from improper crane
setup on outriggers.

RT540E OPERATOR MANUAL
Be sure the outriggers are properly extended and set, and
the crane is level for operation on outriggers.
All four outrigger beams must be equally extended to the
mid position vertical stripe or fully extended position
before beginning operation.
When operating the crane on outriggers, the outriggers
should always be fully extended or locked in the mid-
extend position.
NOTE: The crane also allows operations with the
outriggers fully retracted.
Setting the Outriggers
1. Engage the Parking Brake.
NOTE: To enable outrigger functions: The crane must be in
four wheel drive, the parking brake must be
engaged, the slewing brake must be engaged, and
all crane functions must be off.
2. Position the outrigger floats directly out from each
outrigger to where the outriggers will be properly
extended.
CAUTION
Possible Equipment Damage!
Always depress one of the outrigger/selector switches
before positioning the outrigger extension/retraction
switch to extend or retract. Failure to do this may cause a
hydraulic lock against the individual solenoid valves,
preventing them from opening.
Electrocution Hazard!
To avoid death or serious injury, keep all parts of this
machine, the rigging, and materials being lifted at least 20
feet away from electrical power lines and equipment.
