Emergency operation after a power failure or a defect in the crane’s electrical system.
If your crane comes to a standstill because of a defect in the crane’s electrical system or as a result of
a complete power failure, you can put the crane into emergency operation status (emergency
operation). If the crane is in emergency operation status, you have the opportunity to put the crane into
transport position. (You must then visit an authorised Palfinger workshop immediately). The equipment
(bridging bolt) for putting the crane into emergency operation is always located on the Emergency-Off
solenoid valve. Depending on the design of your crane this is located on the control valve or on the
high-pressure filter.
Putting the crane into emergency operation status with the screw-in bridging bolt:
• Turn the key-operated switch to manual operation.
• Turn the bridging bolt until the seal (plastic tip) breaks off.
• Now put the crane into transport position as described in
Chapter 5.
Putting crane with screw-in bridging bolt on the control valve into emergency operation status:
• Turn the key-operated switch to maual operation.
•
Turn the bridging bolt until the plastic tip (seal) breaks off.
• Then turn the bridging bolt until it hits the stop.
• Now try to run in the hydraulic extendable arm. If this is still
not possible, screw out the bridging bolt one turn (360°) and
try to run in the extendable arm again.
• Once the extendable arms have been run in, put the crane
into transport position as described in Chapter 5.
Once crane movements are possible again the load moment must be
immediately reduced.
• Visit a Palfinger service workshop immediately to have the fault repaired. It is not permissible
to continue to operate the crane!
Putting the crane into emergency operation status as
described above deactivates all safety devices such as
Emergency-Off, load limiting systems and SHB. Loading and
unloading work must not be continued, there is a danger of
tipping over and therefore of fatal injury.
