TECHNICAL DATA

USE

The SR 1450 P sweeper has been designed to perform a complete cycle of industrial and urban cleaning: sweeping, waste collecting and dumping.

NOTE

Any use other than the one described can damage the machine or injure the operators.

The sweeping is carried out by one or more side brooms which convey the debris towards the centre of the machine and a cylindrical main broom sweeps the collected debris into the hopper. The dust is collected and controlled by a fan. The air released into the environment is filtered by a filter. The waste collected in the hopper may be dumped onto the ground or into special boxes at a maximum height of 1,420 mm.

Frame

Rigid, composite supporting frame on rectangular plan, consisting of electrically welded steel plates.

The mechanical components of the machine are suitably sized, according to a 1.4 ÷ 1.5 factor, to withstand the dynamic stress due to the machine operation (supporting frame, hubs, axles, hopper supporting and lifting system, etc.).

Hopper

The hopper is fitted on the front side of the machine and connected to the frame by means of a hinge.

A hydraulic cylinder lifts and overturns the hopper when the waste is to be dumped at a height. The lower part has a hinged skirt, operated by a hydraulic cylinder, which closes the hopper while the waste is being dumped. The front side has a fan operated by a motor. This fan creates a vacuum inside the hopper and in the main broom compartment. Inside it, there is a polyester closed pocket filter connected to an electric filter shaker.

On the front right side there is a side broom whose rotation is operated by a hydraulic motor, while its lifting and lowering are operated by a hydraulic cylinder.

It is possible to install a side broom on the left side as well and a third broom for corner cleaning.

Main broom

It consists of a sweeping roller whose rotation is operated by a hydraulic motor and whose lifting and lowering are operated by a hydraulic cylinder. It is automatically adjusted by the self-levelling device.

Engine

The engine, Lombardini LGW 627, 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). 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

12V electrical system supplied by an alternator operated by the motor. 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
  Working speed: from 1 to 8km / h
  Bending radius (maximum speed of 12km / h ): 3 m
  Bending radius (speed of 5km / h ): 0 m

On sloping ground with good surface conditions and maximum longitudinal slope of 20% :

Bending radius (maximum speed of 5km / h ): 3 m

Bending radius (speed of 1km / h ): 0 m

Maximum crossfall while in transfer: 15% .

Maximum crossfall at 5km / 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.

DISMANTLING, DISPOSAL

NOTE

Material should be disposed according to the law in force.

DISMANTLING

NOTE

Pay the greatest attention when disconnecting the conductors which are live even when the ignition switch is in the "0" position.

Disconnect the cables from the control panels paying attention to the markings on each cable and referring to the wiring diagrams.

Do not remove the reference numbers from the cables and terminal boards.

Hydraulic system dismantling

Dismantle the hydraulic systems referring to the relevant diagrams.

Mechanical dismantling

Before the machine mechanical dismantling, wash all parts that come into contact with the material and thoroughly clean the rest of the machine.

Refer to the chapter "Transportation" for lifting the machine and safety precautions to be taken.

Packaging

Use packing material suitable for the part weight and features.

NOTE

Secure a plate to the packaging showing weight, content and any other information necessary for transportation.

DISPOSAL

Used oils

Used lubricating and hydraulic oils should not be discharged into the environment (waterways, sewerage systems etc.) but they should be delivered to authorized disposal companies. It is recommended to respect scrupulously the law in force. Such materials should be stored in perfectly sealed lidded containers, so that the used oil cannot leak out and contaminate other substances, including rain water. Oil filters should be stored in the same way and delivered to authorized disposal companies.

Used lead batteries

Used batteries fall into the "toxic harmful" waste category. They should be delivered to specially authorized companies for disposal.

If not possible, "temporary storage" should be carried out according to the law in force. This means, first and foremost: having a temporary storage authorization. Store in perfectly sealed plastic containers with a capacity at least equal to the volume of the battery electrolyte. On no account should rain water leak into the containers.

Material collected by the machine

The material collected by the machine can and should be delivered as urban waste or similar to the Public Cleansing Services (according to previous agreements). This is possible provided that the waste does not contain toxic or harmful substances.

When cleaning environments which can present toxic-harmful waste, every single substance should be collected separately and with empty hopper. The waste should then be entirely dumped into special containers whose handling should be carried out according to the law in force and to provincial, regional and state rules.

Scrapping

At end of the machine life, dispose of all the below listed materials which form the machine.

It is recommended to deliver the machine to an authorized company who will provide for the machine correct disposal. For the disposal of oils, filters and batteries, follow the above described procedures. The ABS and metal components can become secondary raw materials. Hoses and gaskets as well as plastic and fibre glass should be sorted into separate groups and delivered to the Public Cleansing Services.

NOTE

Dispose of the machine different materials in suitable refuse disposal sites.

NOTE

Always respect the laws in force in the country concerned.
