Operator's Manual DS 50 / 0002 2
1 GENERAL INFORMATION
The PAT Load Moment Indicator
1
(LMI) DS 50 has been designed to provide the crane operator with the
essential information required to enable the machine to be used 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 capacity of the crane. 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 50 Load Moment Indicator will warn the operator by
sounding an audible alarm and lighting a warning light.
Always refer to operational instructions and load charts provided by the crane manufacturer for
specific crane operation and load limits.
2 WARNINGS
The LMI is an operational aid that warns a crane operator of approaching overload conditions and warns of
overhoist conditions which could cause damage to equipment and personnel.
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 he knows the operation and limitations of indicator and crane.
Proper functioning depends upon proper daily inspection and observance of the operating instructions set
forth in this manual. We draw your attention to section 5 of this manual.

LOAD 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.
