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 diesel Lombardini Focs 702 engine (SR 1450 D) or the
AMRE 36 V motor (SR 1450 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 wheels
– Pneumatic wheels
– Superelastic wheels
– 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.
