This manual has been prepared to provide information and
suggestions for safe operation, rigging, inspection, and
maintenance of Measurement Systems International (

Crane Scales.

It is not intended that the suggestions in this manual take
precedence over existing plant safety rules and regulations,

OSHA

 regulations, or instructions issued by the crane manu-

facturer. However, a thorough study of the following informa-
tion should provide a better understanding of operation and
afford a greater margin of safety for personnel and machinery.

the crane scale operator’s use. It is the responsibility of the
owner to make personnel aware of all federal, state and local
rules and codes and to make certain that operators are
properly trained.
