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
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 in this manual and supplied by the crane
manufacture 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.
The anti-two block switches must be used in ALL operations. Simultaneous
two-hoist working is prohibited in all circumstances.
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 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.
