PAMPHLET 1
Cut-off Values for Boom Cranes with Variable Capacity depending
on Variable Radius
The crane cut-off values are calculated by us on the basis of the load charts and construction drawings
supplies by the crane manufacturers.
These theoretical cut-off values must be checked by testing the crane with weighed test loads in all opera-
ting modes and at least in the following equipment conditions depending on the crane type.
•
Cranes with fixed boom length during operation:
Minimum, medium and maximum radius with shortest, medium and longest boom length as well as with
shortest, medium and longest jib length with these boom lengths.
•
Cranes with variable boom length during operation:
Minimum, medium and maximum radius at each length step as well as with all jibs.

Important notes for crane operators
The LMI is an operational aid which warns a crane operator of approaching overload conditions and also
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 judgement, experience and use of ac-
cepted safe crane operating procedures. The responsibility for the safe operation of the crane 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 the crane/SLI manual to ensure that he knows the operation and limitations of the indicator
and crane.
Proper functioning is dependent upon proper daily inspection and observations of the operating instructions
set forth in the manual.
WARNING
This system can be equipped with an override key on the central micro-processor unit. This
key switch bypasses cut-off functions of the load moment indicator device. The switch may
only be used by authorized personnel during emergency situations. Failure to follow this
instruction may result in property damage and/or personal injury.
