REACTIVATION button of crane functions in the absence of the electric
power.
(!) On the distributor it has been installed an electro-valve with a manual locking
function (fig. 9-9a) which allows to reactivate all the crane functions in case of
absence of the electric power.
Only in these conditions it is permitted to remove the lead seals which protects
the device. Push the button and turn it into the clockwise sense; the button
stays in stable and closed position.
(!) When the electric power is restablished, remember to put the button in its
original position, turning it into the anti-clockwise sense. (Fig. 9b pos.3-4)
Rubinetto esclusore di EMERGENZ
A del limitatore
Every electrovalve is installed with a screwed tap (emergency exclusion
tap), which must only be used in case of emergency, testing or other
abnormal situations when it is not possible to carry out any of the move-
ments allowed by the device. (Such a probability generally occurs when
the extension booms are completely re-entered or the loads are conside-
rable and voluminous.) Only In these situations it is permitted to remove
the lead seals which protect the device. Slacken the lock nut of the
screwed tap fig. 10-11 (14 mm hexagonal spanner), completely screw in
the tap (5 mm allen key) and re-tighten the lock nut.
(!) ATTENTION (!)
When the operator uses this device, it means that he wishes to over-
ride the lifting moment limiting device in order to make some manoeuvres
(which would be impossible with the device active) that bring the moment
to within the level, but involve an overload condition. In such an emer-
gency condition (where the lifting moment limiting devicehas been
disabled), the operator must be:
- carefully consider the manoeuvres required to return to normal
working condtions;
- calmly and carefully assess the type and scale of the hazards
arising from these manoeuvres and the possible reaction of the
crane (tipping over, frame overload, uncontrolled fall of the load due
to a hydraulic system overload etc...);
- make all movements as slowly as possible to reduce the dynamic
overload to the minimum.
After such emergency operations and prior to re-use of the crane, you must
immediately go to FASSI authorised Center for testing the structure and
re-sealing of the device.
(!) Interferences with the valves or removal of the lead seals release the
Manufacturer from any responsibility and invalidate the warranty.
(!) ATTENTION (!)
The presence of the lifting moment limiting device does not release the
user from the obligation to respect what is indicated on capacity plates
and lifting curves.
