MAIN
DESIGN
The
two
main
component
sections
are
the
carriage
and
the
main
head.
The
handle
(Fig.1.1)
on
the
frame
is
adjustable
in
height
and
allows
the
operator
to
work
in
a
correct
and
safe
working
posture.
The
halogen
spotlight
(Fig.1.2)
enables
the
operator
to
work
in
darker
areas.
Existing
lighting
system
does
not
replace
adequate
overhead
lighting.
A
frame
(U
‐
joint
technology)
on
top
of
the
motor
base
is
providing
the
main
head
a
possible
to
move
to
all
sides
and
it
gives
more
grinding
capacity.
The
controls
are
positioned
on
top
of
the
electrical
box
(fig.1.3)
The
electrical
box
(fig.1.3)
contains
the

devices
and
the

The
motor
feeding
cable

plugged
in
the
socket
located
on
the
bottom
of
the

the
opposite
side
of
the
frame,
so
that
the
weight
of
the
water
has
no
influence
on
the
operation
of
the
machine.
The
frame
weight,
on
the
other
hand,
is
fully
absorbed
by
the
driving
wheels.
An
electric
pump
sprays
the
water
through
a
front
sprayer
or
internal.
The
motor
is
mounted
on
the
base
plate
and
is
driving
the
three
heads
with
a
belt
system.
The
planetary
head
is
driven
by
a
second
flat
belt.
The
machine
is
driven
by
no
maintenance
Helical
