USER MANUAL

Engine

The engine, a Diesel Lombardini Focs 1204 (SR 1800C D) or motor Amre 48V (SR 1800C B) drives the hydraulic system pumps.

Front wheels

Pneumatic wheels

Superelastic wheels

They are independent, fastened to the frame by means of a hub with built-in brake drum. The brakes are hydraulic. The parking brake is mechanical.

Rear wheel

Pneumatic wheel

Superelastic wheel

The rear wheel is the driving and steering wheel. The steering is operated by a hydraulic cylinder connected to the power steering. A hydrostatic variable delivery pump with servoassisted control supplies a drive hydraulic motor for forward and reverse gear.

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). The forward and reverse drive are adjusted by a hydraulic assist operated by a pedal. In the second circuit a gear pump feeds the power steering and a distributor which controls: the hopper lifting cylinder, the side broom lifting and rotation cylinder, the skirt opening and closing cylinder; the power steering controls the steering cylinder.

In the third circuit the gear pump feeds a distributor which controls the main broom lifting/lowering and rotation cylinder and the fan hydraulic motor rotation.

All circuits are protected by suction filters and safety valves.

Electrical system

SR 1800C 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 1800C B: power electrical system supplied by a 48 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 and by the power supply itself, that cuts the voltage supply in case of short circuit and then restarts it at circuit reset.

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: 14 km/h

Working speed: from 1 to 8 km/h

Bending radius (maximum speed of 14 km/h): 3 m

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.
