Load Moment Indicator(safe load indicator or Crane computer) is a device which is installed on various sorts of cranes like mobile, crawler, tower, gantry, portal, marine and offshore crane. It alert the operator if the lift is exceeding the safe operating range. In some cases, the device will physically lock out the machinery in circumstances it determines to be unsafe.
It controls the lifting equipment to function as per the manufacturer's suggested safe load charts. Each of the measured parameters like load weight, working radius, control limit,angle and extension of the crane boom, etc will then further be displayed in the operator's cabin.
Data Logger Can Be Customized
The data logger system records the moment system parameters and the alarm data of moment
system for crane in using status.The data logger protects the parameters and system data.If there are
security incidents, these parameters provide the parameters and data for the crane operation; Equipment
maintenance personnel can also use data to analysis system performance and make reference for
equipment maintenance.
Data Record Capacity
1 record per second, 1 hour is 3600 records, 24 hours a day continuous record, then the day
is3600 * 24 = 86400 records. Each record 180 bytes (the longest), then total of 15.6M per day data, about
16M. If Encrypted data, 4G memory, can only be calculated by 2G, that is 1870M. 1870/16 = 116.5
days ,4G memory can record about 4 months.
1 record per 2 seconds, 1 hour is 1800 records, 24 hours a day continuous record, then the day is
1800 * 24 = 43200 records. Each record 180 bytes (the longest), then total of 7.8 M per day data, about 8
M. If Encrypted data, 4G memory, can only be calculated by 2G, that is 1870M. 1870/8 =233 days .4G
memory can record about 8 months.
