9.2 Description
The frame is a unique structure in
painted steel.
On it are coupled the steering system
including the levers for the activation of
the drying system and mechanical fric-
tion system, and the traction system.
The steering system is composed by a
steering column connected to a steer-
ing wheel , which acts directly on the
front wheel. The steering is ensured by
a pinion and a sprocket, connected by a
chain.
On top of the steering column, there
are the levers for the activation of the
squeegee and the mechanical friction
system.
To ensure the proper functioning of the
two systems, in the steering column are
installed some microswitches that act di-
rectly on the affected systems.
The traction of the machine is guar-
anteed by an electric motor installed in
combination with a gear, whose output
shafts act directly on the rear wheels of
the machine, ensuring traction.
The gear motor is equipped with an
electrobrake which ensures the immobil-
ity of the machine when it is not moving.
Both the front wheel the rear wheels are
non-marking and antiskid.
