SYSTEM DESCRIPTION
The PAT load moment limitation and control system consist of an
iFLEX5
central unit, an
iSCOUT
expert compact
CAN console and various sensors for collection the measured values.

Components of the LMI system with iFLEX5
The system operates on the principle of reference/real comparison. The actual value is compared
with the calculated reference values and evaluated by the system. An overload warning signal is trig-
gered on the display and operating console once limit values are reached. All crane movements that
increase the load moment are switched off at the same time.
The crane-specific data specified by the manufacturer, such as load capacity charts, boom weights,
centers of gravity and dimensions, are stored in the central data memory. This data is the reference
information used to calculate the operating conditions.
The boom angle is registered by means of an angle sensor that is mounted on the boom. The crane
load is determined indirectly with the aid of force and angle sensors.
