Hydraulic System; Electrical System; Safety Systems - Nilfisk SR 1450 B Manuel D'utilisation

ENGLISH
Dashboard / Controls
Installed on the left side of the driver's seat. The warning lights and meters are on the machine dashboard, while the accessory
controls are on the three levers of the hydraulic distributor.

Hydraulic system

In the fi rst 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 fi lters 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 accessory 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 specifi ed 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.
