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 friction system, and the
traction system.
is composed by a steering column con-
nected to a steering wheel , which acts
directly on the front wheel . The steer-
ing is ensured by a pinion and a crown,
connected by a chain.
welded directly onto the steering, while
the crown is installed on the assembly
front wheel. On top of the steering col-
umn , there are the levers for the acti-
vation of the squeegee and the mechani-
cal friction system. To ensure the proper
functioning of the two systems, in the
steering column are installed some mi-
croswitches that act directly on the af-
fected systems. The traction of the ma-
chine is guaranteed by an electric mo-
tor 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
immobility of the machine when it is not
moving. Both the front wheel the rear
wheels are non-marking and antiskid.
