24、ractice has shown that there are three main benefits to be obtained from the accurate logging of crane performance data. event recordinga) event recorders record the events before, during and after a lift. This data can be used for accident analysis and to monitor operator performance (for example,
25、persistent over-lifting). This allows a crane owner to look at the events leading up to an incident, such as overturning or structural failure, so that the exact mass and position of the load can be determined, and hence the cause of the incident ascertained. The data can also be used to identify op
26、erators who habitually abuse the crane.Condition monitoring b) To provide information for condition monitoring (see ISo 12482-1) against the crane manufacturers specified criteria.The recording of the magnitude of lifts as a percentage of rated capacity, the duration of the lift, and the duration of
27、 each of the crane motions, allows an assessment of component and structural life to be made and provides an accurate indication of the need for thorough examinations, based on the lifting cycle history rather than the traditional time period basis. This process ensures that components are examined
28、and replaced at a time that optimizes cost control and safety.Crane usage analysisc) To analyse lift data for operational and marketing purposes and to guide future purchases. Being able to obtain all the operational data on a crane, such as how long it has worked in a day, what duty it was rigged o
29、n, what percentage of rated capacity was used and whether a large capacity hook block or fly jib was used, can help to establish what customers are using a crane for, and whether it is worth carrying a fly jib with every crane. This information also enables operator hours to be accurately establishe

40、ed up) at the beginning of a work period and switched off (powered down) at the end of a work period4 Data logging system 4.1 GeneralData logging systems generally use some form of computer to capture, process, store and transfer the data so the basic system requirements shall be established before
41、software and hardware are specified to ensure that the computer is capable of performing the required tasks.4.2 Data parameters4.2.1 Functions to be monitoredThe data logging equipment shall be capable of monitoring:the minimum parameters specified for all cranes in annex B; anda) the minimum parame
42、ters specified for specific crane types in b) annex C, as appropriate.NOTE 1 The crane parameters to be logged vary with crane type, model and specific requirements of the manufacturer and crane owner/user. Measurement and recording of these parameters can either be derived from existing sensors or
43、through the fitment of additional transducers. NOTE 2 Information on limiting and indicating devices for cranes is given in BS EN 12077-2.4.2.2 Monitoring frequencymonitoring frequency shall be set to ensure that sufficient data are captured over a given period to enable a meaningful analysis of a m
44、ajor event (such as a crane overturn) to be made, and to ensure that adequate load spectrum data are collected for condition monitoring purposes.NOTE The data sampling frequency for the parameters being logged will vary with crane type, model and specific requirements of the manufacturer and crane o

46、ing system shall be such as to ensure that the data collected and stored accurately represent the cranes usage over a given period.4.3.2 Threshold valuesThreshold values shall be set at a level that will avoid false recording of events.NOTE For example, if the threshold values are too low, every tim
47、e a load bounces and the dynamic element of the total load force changes, the bounce is counted as the start of a new lift. This has the effect of rapidly filling the data logger memory with spurious data, thereby negating the benefits of data logging.4.3.3 Rigging and other non-lifting activitiesTh
48、e data logging system shall be set to ensure that rigging and other non-lifting activities permitted by the crane manufacturer are not counted as overloads.4.3.4 Full memory protocolThe data logging system shall be set to ensure that if the data storage memory fills up through lack of regular downlo
49、ading, the oldest data are automatically deleted to allow new data to be stored. NOTE This ensures that the latest data are always available for analysis in the event of an accident.4.4 In-logger processingprovision shall be made for processing the captured data within the data logger for functions such as:the evaluation of data against alarm threshold values;a) the computation of the remaining safe working period;b) the processing of data for visual display.c) 4.5 Operator identityIn order to prevent unauth
