Electrical System
The
el
ect
rical system is logically struc-
tured, easily serviced a
nd
comp
letely
coordi
nat
ed
wit
h the
other
trucks
in
the
Kalmar range.
The
system
is
suppli
ed
by
two
12V batteries
connected
in
ser
ies charged by
an
a
lt
er-
nator,
with
re
lated electronics for recti-
ficati
on
and
current
stab
ilization.
The
system
provides
high
power
levels
even
at
low
engine revs. Th e electrical
fuses, relays and
connectors
are
l
ocated
in
an
eas
il
y accessible
position
withi
n a

l electrical unit inside
the
cab,

Drive
axle
The
Kessler
D81
drive axle is
of
an
extreme
ly robust design to
be
able to
cope
w
ith
tough
wo
rking environ-
ments
such
as
in
the
paper
and
pulp
indu
st
ries, saw mills,
stee
l
wo
rks,
ports
and
t
ermina
l
s.
The
axle has reduction in
two
stages -
diff
ere
ntial and
hub
reduction
-
which
ensures
a minimum
of
strain
on
the
transmission system.
The
drive axle is
fitted w
ith
hydraulic braking system
(see
Servi
ce
Brake System).
Parking Brake System
The
parking brake system consists
of
a
dry
disc
brake
on
the
in-going shaft
of
the
drive axle. The disc brake
is
applied
by
means
of
a powerful
sp
ring in
the
parking
brake
cylind
er
and
is released
by
means
of
hydraulic
pressure
from
the
parking brake valve
in
the
cab.

Service Brake System
The
service brake system
is
of
the
Wet
Disc Brake type, a system w
ith
o
il
-
coo
led discs
that
are a
lt
ernate
ly
fixed
to
and rotating
with
the
hub.
When
the
brakes
are
app
li.
ed
,
the
discs are
pressed
together
by
hydraulic
pressure
from
the
brake pedal,
whic
h
provides
extremely effective braking.
The
system is v
irtu
a
ll
y
maintenance
free
and
can
cope
wit
h heavy l
oads
over
an
extended
period
of
time,
with
no fade
and
w i
thout
the
need
for
brake
adjust-
ments. The
heat
generated
durin
g
braking is dissipated via a
coo
ling
circ
uit
in w hi
ch
the
truck
's total
volume
of
hydraulic fluid
comes
int
o
play. A
spec
ial filter
protects
the
braking system from any impmities.
