On the basis of analyzing present overload equipment of crane

development of multifunctional overloading monitor and recorder of crane is proposed.Functions of precision measurement

alarming

and restriction operation of the monitor and recorder are realized

in addition the historical operation data can be transferred to U-disk by using CH375.In order to meet demand of real time monitor

technology of GSM is adopted to transmit real-time data of crane to supervision room.So the real-time monitor is realized indeed.It is proved that the monitor and recorder completes full functions

and it has good reliability and real-time.
