reater
than
the
legal
maximum,
sensor
E584
is

This
puts

If
the
permitted

load
increases
further
(>
10
tons),
sensor
E507
automatically
lowers
the
trailing

xle.
If
the
a
xle
has
been
lifted,
F097
(proximity
switch
for
trailing

ensures
that

that

This
is
to

As
a
result,
the
lifting-gear
motor
relay
(G052)
will
also
be
activated,
thus
activating
the

When
a
pressure
of

is
reached,
the
limit
switch
(E524)
switches
the
