MANOEUVRES OF THE OUTRIGGER RAMS IN CASE OF AN ELE-
CTRICAL FAILURE
In case of an electrical failure, electrical malfunctions, you cannot
use the selectors on the push-button panel and so it is necessa-
ry to operate directly the outrigger distributor bank (fig. 4).
In such an emergency condition, the operator shall make sure
that no one is within or passing in close proximity to the working
area of the outriggers, neither from the operator side nor from the
opposite side. The operator shall be able to visually see the
whole working area at all times. If it is not possible he shall team up
with a co-worker (i.e. located on the opposite side of the crane) in a
way not to harm each other while manoeuvring the outriggers (i.e.
disengage of the locking devices of the outrigger supports, see fig.
5-5a). To operate with the distributor bank use the two levers
without thread in equipment.
PICTURE LIST (fig. 4):
Levers CD Controls to select the outrigger supports and rams.
Levers C Control of the selected outrigger support or ram.
T Electric deviator of the crane-outriggers (fig. 4a)
Example: re-entry of the outrigger ram S1
- tighten the T screw (fig. 4a)
- activate the corresponding lever CD towards "S1" and keep it in
position.
- activate the lever C to control the descent of the ram.
- to reactivate the crane functions loosen the T screw, to the previous
position (see fig. 4a)
After such emergency operations and prior to re-use of the crane,
you must immediately go to a FASSI authorised Center for the
repair of the fault and re-sealing of the device.
(!) ATTENTION (!)
Interferences with the valves or removal of the lead seal release the FASSI
GRU from any responsibility and invalidate the warranty.
