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 two fans operated by a motor. These fans create 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, a diesel Lombardini LDW 1003, 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 wheels

Pneumatic wheels

Superelastic wheels

The rear axle is driving and steering. 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.

Joystick

This is a new system, fitted on sweepers for the first time, by means of which all the controls are grouped together in a single lever. The push-button switches located on the joystick perform all of the machine operational functions.

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

12 V electrical system. The circuits are protected by lamellar fuses housed in a relevant fuse box.
