USER MANUAL
33014811(1)2005-07 A 7
Dashboard
Fitted on the upper part of the frame and under the steering
wheel, the dashboard houses the machine warning lights and
instrumentation.
Hydraulic system
In the first circuit a variable delivery pump feeds the drive
hydraulic motor (rear wheel). In the second circuit a gear
pump feeds a lever double-acting distributor. The distributor
operates the lifting cylinders and the broom motors. All
circuits are protected by suction filters and safety valves.
Electrical system
SR 1450 D: 12 V electrical system supplied by an alternator
operated by the engine. The circuits are protected by lamellar
fuses housed in a relevant fuse box.
SR 1450 B: power electrical system supplied by a 36 V
battery. The service electrical system is supplied by a 12 V
power supply. The circuits are protected by lamellar fuses
housed in a relevant fuse box.
Stability
Machine stability depends on the conditions in which it is
used.
If the machine is used within the conditions of use specified in
the manual, it is stable. To this end, the following tests were
carried out under the same conditions on a prototype identical
to the series model and no stability problems arose. The
conditions were:
Flat ground with good surface conditions:
– Transfer maximum speed: 13 km/h (SR 1450 D)
Transfer maximum speed: 8 km/h (SR 1450 B)
– Working speed: from 1 to 8 km/h
– Bending radius (maximum speed of 12 km/h): 3 m (SR
1450 D)
– Bending radius (maximum speed of 7 km/h): 3 m (SR
1450 B)
– Bending radius (speed of 5 km/h): 0 m
On sloping ground with good surface conditions and
maximum longitudinal slope of 20%:
– Bending radius (maximum speed of 5 km/h): 3 m
– Bending radius (speed of 1 km/h): 0 m
Maximum crossfall while in transfer: 15%.
Maximum crossfall at 5 km/h: 20%.
The tests were carried out with lowered and empty hopper.
For different conditions of use, the machine operator should
be able to assess the limits of the machine and should, in any
case, follow the indications laid down in the manual.
