Crane Computer Lmi

Truck crane/Mobile crane LMI (load moment indicator)

Crane computer LMI (Load moment indicator) is a jib type crane safety protection device, which is applicable to various types of automobile crane, truck crane, gantry crane and the fixed hanging.
Crane computer LMI provides the crane operator with effective operation information, which enables the crane to be used effectively within range of its designed parameters. Under cooperation of a variety of signal sensors, the power limiter can provide real-time information about the length of the lifting arm, the angle of the lifting arm, the working height, the working range, the rated lifting weight and the actual lifting weight.
When the crane operation is beyond the allowable range of safety, the power limiter will emit sound and light alarm to remind the operator to stop the illegal operation, and send out control signal of the automatic lock to stop the dangerous direction movement.
We can supply LMI system for China XCMG trcuk cranes, ZOOMLION truck cranes, Sany truck cranes, and Changjiang truck cranes.
