Frame
Rigid, composite supporting frame on rectangular plan,
consisting of electrically welded steel plates.
The mechanical components of the machine have been
suitably sized, with a 1.4 ÷ 1.5 factor, to withstand the
dynamic stress created by the machine in operation
(supporting structure, hubs, axles, support systems and
hopper lifting, etc.).
6
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 diesel Lombardini Focs 903 engine (SR 1550C D) or the
AMRE 36 V motor (SR 1550C 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.
