General Information

1 GENERAL INFORMATION
The PAT Load Moment Indicator1(LMI) DS 350 has been designed to provide the crane operator with
the essential information required to operate the machine within its design parameters.
Using different sensing devices, the Load Moment Indicator monitors various crane functions and
provides the operator with a continuous reading of the cranes capacity. The readings continuously
change as the crane moves through the motions needed to make the lift.
The LMI provides the operator with information regarding the length and angle of the boom, working
radius, rated-load and the total calculated-weight being lifted by the crane.
If non-permitted conditions are approached, the DS 350 Load Moment Indicator will warn the operator
by sounding an audible alarm, lighting a warning light and locking out those functions that may
aggravate the cranes condition.
2 WARNINGS
The LMI is an operational aid that warns a crane operator of approaching overload conditions and of
overhoist conditions that could cause damage to equipment and bodily injury.
The device is not, and shall not be, a substitute for good operator judgment, experience and use of
accepted safe crane 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 the operation and limitations of indicator and crane are
known.
Proper functioning depends upon proper daily inspection and observance of the operating instructions
set forth in this manual. Refer to Section 6. Pre-Operation Inspection and Calibration Verification of
this manual.
The LMI can only work correctly, if all adjustments have been properly set. For correct
adjustment, the operator must 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.
1LOAD MOMENT: generally the product of a force and its moment arm; specifically, the product of the load and the load-radius. Used in the
determination of the lifting capacity of a crane

3 SYSTEM DESCRIPTION
The PAT Load Moment Indicator DS 350 consists of a central micro processor unit, operating
console, length/angle sensor, pressure transducers, and anti-two block switches.
The system operates on the principle of reference/real comparison. The real value, resulting from the
pressure measurement is compared with the reference data, stored in the central processor memory
and evaluated in the micro processor. When limits are reached, an overload warning signal is
generated at the operators console. At the same time, the aggravating crane movements, such as
hoist up, telescope out and boom down, will be stopped.
The fixed data regarding the crane, such as capacity charts, boom weights, centers of gravity and
dimensions are stored in memory chips in the central processor unit. This data is the reference
information used to calculate the operating conditions.
Boom length and boom angle are registered by the length/angle sensor, mounted inside the cable reel
which is mounted on the boom. The boom length is measured by the cable reel cable which also
serves as an electrical conductor for the anti two-block switches.
The crane load is measured by pressure transducers attached to the piston and rod side of the hoist
cylinders.
The interactive user guidance considerably simplifies the input of operating modes as well as the
setting of geometry limit values.

3.1 SYSTEM FUNCTION
Upon switching on, the system starts with an
automatic test of the LMI system, of lamps
and audible alarm. During the test, the LC
display shows the initial logo.
If the system was turned off for more than
two hours, the setup configuration has to be
entered after the system test. ( Chapter4)
First, the operating mode is determined by
an interactive step-by-step interrogation of
the rigging states.
Next is the interactive input of the reeving.
Now the LC display shows in symbols all
inputs and awaits acknowledgment or
cancelling.
Upon acknowledgment of the inputs the
system is ready for operation.
