BOJIN LMI (Load moment indicator) for mobile/truck crane

The B-A100 load moment indicator provides the crane operator with effective operation information, which enables the crane to be used effectively in the range of its design parameters. With the aid 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 LMI will emit sound and light alarm to remind the operator to stop the illegal operation, and send out the control signal of the automatic lock to the dangerous direction movement.
