System Identification

The PME system provides two primary safety functions
1.
2.
Both safety functions are achieved through real time monitoring of some
or all of the machine's moving parts ( booms, other articulations, turret
etc ) and its environment ( ground pitch and inclination, load etc) and
actively determining the safety of the current operation where
appropriate limits have been set.
The Lifting Stability function falls into two sub classes
The Machine Envelope Monitoring function has a single class
During operation the indicators on the left are displayed on the screen
to clearly identify the function supported by your PME500. Functions
may not be available i.e. when in non-lifting mode or when envelope
monitoring is switched off, if this is the case a cross will be painted over
the relevant function icon.
Combinations of these functions may be present, it is essential that the
functions of the system installed are identified and understood.

Lifting Stability
Machine Envelope Monitoring
Rated capacity indictors (RCI) warn of potential instability when
the machine is involved in lifting operations. Any motion which
reduces the safe working load will not be inhibited at any time.
Rated capacity controllers (RCC) prevent instability when the ma-
chine is involved in lifting operations. This is achieved by
hydraulically stopping unsafe movements of the machine which
could cause the machine to tip.
Machine envelope controllers (MEC) prevent movements that
would bring parts of the machine into hazardous areas, most nota-
bly height restrictions when working under overhead wires.
