Abstract: FIELD: mechanical engineering; load-lifting and transportation. 
     SUBSTANCE: according to both versions of proposed method, parameters of load-lifting machine are recorded by obtaining, primary processing and converting of data on operating parameters and subsequent recording of said data by means of microprocessor calculator or microprocessor calculator or microcontroller in memory device of load-lifting machine and copying or re-writing, when necessary, of recorded data in mobile data medium and subsequent re-writing or copying the data from mobile data medium in to computer for secondary processing.  According to one version, copying or re-writing of additional data from mobile data medium into memory device or into memory of microprocessor calculator or microcontroller on load-lifting machine or into computer is carried out additionally.  Said additional data are used as data of parameters recorder of preceding period of operation of load-lifting machine or for changing program of operation of microprocessor calculator or microcontroller under primary processing conditions or conversion of data on operating parameters of load-lifting machine before entering them in memory device or under conditions of implementation of load-lifting machine protection functions and also for data exchange with mobile data medium.  In the latter case additional data are presented in form of identificator of mobile data medium or biometric data of operator.  According to other version, checking of reliability of data is carried out additionally, and warning signal is shaped, if data are not reliable.  Checking for reliability is carried out by comparing values of separate operating parameters of load-lifting machine and revealing their discrepancy under different operating conditions of load-lifting machine.  Electronic unit in load-lifting machine parameters recording device includes microprocessor calculator or microcontroller and memory device and is made for connection of mobile data medium with non volatile memory.  Moreover, electronic unit is made for reading out data from mobile data medium into memory device or microprocessor calculator memory or memory of microcontroller with possibility of using the data as data from parameters recorder of preceding period of operation of load-lifting machine, or as part of program of operation of microprocessor calculator or microcontroller at processing or conversion of data on parameters of operation of load-lifting machine before entering them in 
     memory device or at implementation of load-lifting machine protection functions, or with possibility of limitation of access to data exchange with mobile data medium depending on said additional data presented in form of identificator of mobile data medium or biometric data of operator.  Group of inventions makes it possible to reprogram algorithms of operation of recorder and protection system of load-lifting machine with possibility of entering into recorder data on preceding period of operation of load-lifting machine, protection of information stored in recorder from random or deliberate distortion and prevention of access to reading out and processing of recorder parameters by unauthorized personnel. 
     EFFECT: improved operation reliability.
