ABSTRACT:
This invention relates to a device for restricting the operation of cranes within the predetermined operation allowable range, said device having an operation control board on which is mounted a reduced-scale pattern which represents the operation range of the crane at the operation site to give a sectional indication divided into allowable range operation and restricted range operation, and having discrimination means which describes the locus of motion corresponding to the top of the crane boom on said operation control board, thereby making it possible to restrict the operation of the crane based on the discrimination of the section indication.
