7.5 Stability Overload Control
Where an overload condition occurs the machine hydraulics will be locked to prevent any
further dangerous movements. Only those movements that allow safer operation remain
active, all slewing is prevented. The radius cannot be increased and the load cannot be
raised. The internal and external alarms will sound in conjunction with visual indicators on
the display.
7.5.1 Hydraulic Limitation Control
The system will cut motion to the appropriate ar-
ticulation in a hydraulic limit state via internal and
external alarms in conjunction with visual indica-
tors on the display. If a particular lift is limited by
hydraulic capacity rather than stability, the maxi-
mum safe working load will be shown in RED. Hy-
draulic limitation is more likely to occur at short
radii.
*Where an overload condition occurs the machine hydraulics will be locked to prevent
any further dangerous movements. Only those movements that allow safer operation re-
main active. The radius cannot be increased and the load cannot be raised.
After three seconds a soft override will become available if the supervisor key-
switch is in the SET position, see sections 5.5 and 7.6.1.
In the event of an approach to overload or an overload condition, the lifting
point should only be moved in a direction that increases the safe working
load. See section 4 for further information.
If the load is greater than 105% of the
maximum safe working load
 The load capacity indicator will be red
 The red LED will flash
 The internal and external alarm will
sound
 The message shown here will be
displayed
 Motion control of the machine will
operate, motion cut is indicated by
RED arrows, safe motion is indicated
by GREEN arrows
