BOOM EXTENSION
To avoid death or serious injury, follow the procedures in this
manual during erection, stowage, and use of the boom
extension.
Install and secure all pins properly.
Control movement of boom extension at all times.
Do not remove right side boom nose pins unless boom
extension is properly pinned and secured on front and rear
stowage brackets.
Do not remove all the pins from both front and rear stowage
brackets unless the boom extension is pinned to the right
side of the boom nose.
Properly inspect, maintain, and adjust boom extension and
mounting.
When assembling and disassembling boom extension
sections, use blocking to adequately support each section
and to provide proper alignment.
Stay outside of boom extension sections and lattice work.
Watch for falling or flying pins when they are being removed.
PARKING AND SECURING
When parking on a grade, apply the parking brake and chock
the wheels.
Section 3 of this manual provides instructions for parking and
securing a crane when it is to be left unattended. These
instructions are intended to allow the crane to be placed in
the most stable and secure position. However, Manitowoc
recognizes that certain jobsite conditions may not permit the
boom and boom extension of a crane to be fully lowered to
the ground. When a qualified person at a jobsite determines
that it is not practical to lower the boom to the ground, we
recommend the following additional instructions be followed:
•
The crane should be left in the smallest, most stable,
valid operational configuration that the job site
practically allows.
•
The crane can not be left running, with a load on the
hook, or in erection mode, or in wind conditions in
excess of allowed values.
•
The boom should be retracted as far as is practical, the
crane configured in as stable a configuration as possible
(boom angle, superstructure orientation, boom
extension angle, etc.)
•
In high winds the boom and boom extensions should be
lowered, or secured. 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.
SHUT-DOWN
Use the following steps when shutting down the crane:
•
Engage the parking brake.
•
Fully retract and lower the boom.
•
Engage the swing lock pin or 360 degree swing lock (if
equipped).
•
Place crane function power switch to OFF (if equipped).
•
Place controls in neutral position.
•
Shut down the engine and remove the ignition key.
•
Chock the wheels, if not on outriggers.
•
Lock the operator’s cab (if applicable) and install vandal
guards, if used.
COLD WEATHER OPERATION
Cold weather operation requires additional caution on the
part of the operator.
Check operating procedures in this manual for cold weather
starting.
Don’t touch metal surfaces that could freeze you to them.
Clean the crane of all ice and snow.
Allow ample time for hydraulic oil to warm up.
In freezing weather, park the crane in an area where it
cannot become frozen to the ground. The drive line can be
damaged when attempting to free a frozen crane.
If applicable to your crane, frequently check all air tanks for
water in freezing weather.
