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 fi tted 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 fi lter connected to an electric fi lter 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.
Motor
The engine, a Diesel Lombardini Focs 702 (SR 1450 D) or motor AMRE 36 V (SR 1450 B) drives the hydraulic system pumps.
Front 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
– Superelastic wheels
– The rear wheel is the driving and steering wheel. The steering is operated by a steering gearbox connected to the wheel by a
chain. A hydrostatic variable delivery pump with servoassisted control supplies a drive hydraulic motor for forward and reverse
gear.
