1.Breif introduction
This manual is made for the crawler cranesQUY260 of Zoomlion. Please read the manual carefully
according the collocation of different types.
2.General information
The Hirschmann load moment indicator (LMI) iFLEX5 has been designed to provide the crane
operator with the essential information required to operate the machine within its design parameters.
Using various sensing devices, the Load Moment Indicator monitors various crane function and
provide the operator with a continuous reading of the load capacity. The readings continuously change
as the crane moves and lifts. The LMI provides the operator with information regarding the length and
angle of the boom, tip height, working radius, rated load and total weight of actual lift.
If non-permitted condition is approached, the iFLEX5 Load Moment Indicator will warn the operator
by sounding an audible alarm, lighting a warning light and cutting off those functions that may
aggravate the crane’s condition.
3.Warnings
The LMI is an operational aid that warns a crane operator from approaching conditions of overloading
and over-hoisting which would cause great damage to the equipment and personnel.
The LMI could only prevent overload of the crane boom in lengthwise vertical level but could not
prevent accidents caused by inclined hoisting, wind loading, inclination or foundering of the road and
rail or driving oversteps. So the operators and other people shall not ignore safe management and
operating procedures of the crane because of the existence of the device. It is not, and shall not,
substitute for a good operator’s judgment, great experience or standard operating procedures. The
responsibility for the safe crane operation shall remain with the crane operator who shall ensure that all
warnings and instructions supplied are fully understood and observed.
Prior to operating the crane, the operator must carefully and thoroughly read and understand the
information in this manual to ensure that he knows the operation and limitations of indicator and crane.
Notice：The LMI can only work correctly, if all adjustments have been properly set. For correct
adjustment, the operator has to answer thoroughly and correctly all questions asked during the setup
procedure in accordance with the real rigging state of the crane. To prevent material damage and
serious or even fatal accidents, the correct adjustment of the LMI has to be ensured before starting the
crane operation.

4.System configuration
User Manual
The system is composed of Expert
console, iFLEX5 controller, KMD
force sensor, angle sensor, etc.
When operator sets current OM and
reeving according to the key of the
display, the signal is transmitted to
controller and display by pull sensor.
The display shows the actual weight
and rated weight. The actual weight
and rated weight is compared in the
controller. Once the rated weight is
reached, the controller will indicate
the overloading warning signal and
send warning sound. At this moment,
operator is forbidden to operate to
dangerous direction.
4.1 System configuration
4.1 Controller
Controller: 32 digit industrial control
PLC system and high-powered
processor qualify the requirements of
bad environment for all kinds of
industrial system. IFLEX5 module is
composed of base board or base
board add expansion board.
Customers could choose different
IFLEX5 module according to their
own needs. Each module can be
connected by CANBUS. Due to the
4.2 Controller
building block mode, the IFLEX5 is
not only applicable to medium and
small control systems, but also to big
and complicated control systems.

4.2 Console
User Manual
Console: a 640*480 color LCD of industrial
lattice screen graph liquid crystal. It can
display all the operational data that you are
concerned. The combination between the
Graphical display and Genersys software
achieve the on-line program for graph. The
strong graph compiled capability is
incomparable with other Industrial Control
displays.
4.3 Console
4.3 KMD Force sensor
4.4 KMD force sensor
4.4 Angle sensor
4.5 Angle sensor
The system adopts shock-proof,
anti-electromagnetic interference, and high
precision and low zero drift. As the sensor has
the compensated function of temperature, it
can retain its own quality even with continuous
and high-intensive operation.
Remarks：all the analog sensor for iFLEX5
system must be current type or with CAN-bus.
Voltage sensor have to change to current
sensor.
The WGC angle sensor is for exact measurement
for angle of all kinds of construction machines.
Distinguished by its compact exterior, the sensor
has the feature of simple installation, high
efficiency and accuracy, no hysteresis, high
protective class, long time service life and suited
to extreme ambient condition.

User Manual
5.1 OM icon
Operators could learn present crane state through the working mode icon on top part of the console.
A.Error code icon
To indicate which part of the LMI is abnormal. Operators then can remove
difficulties accordingly, and the LMI will back to normal condition.
B.Reeving icon
To display present reeving.
C.OM code icon
To display current OM code.
D.CAN-bus mode icon
E.A2B alarming icon
F.Pre-warning icon
G.Stop movement icon
H.Time display icon
To display the CAN communication mode between the console and the
controller. When the light is on, the CAN communication is abnormal.
This means the hook is reaching to the ultimate height, operators shall stop
movement of the hook right away.
This means the moment percentage is over 90％, operators shall be
awared of that.
This means the movement of the crane is very dangerous, operators shall
back to the safe side. Or the LMI is abnormal, the problem shall be solved
immediately.
To display the local time.
