Load Limiter (LMI)

This microprocessor device has been designed to prevent vehicles with telescopic boom from tilting due to over-load.

The system consists in a Strain Gauge Sensor, to be installed in the most strategic point, and an electronic device that detects the electric signal and displays the load level through 6 LEDs.

A beep and two relay outputs are activated when the set Prealarm and Alarm thresholds are reached, allowing the operator to intervene immediately for vehicle safety.

Functions

Proportional display of the Load by using 6 coloured high-brightness LEDs.
The Siren is activated as soon as the Prealarm and Alarm thresholds are reached.
Fully automated operation. No operator intervention required.
Management of Stabilisers.
Prealarm and Alarm dry contacts are used to slowdown and stop telescopic boom extension.
Strain Gauge Sensor operation.
Guided Calibration to facilitate calibration operations in the field.
Automatic Self-Test upon activation.
Test Function to verify the proper operation of the relays, LEDs and siren at any time.
Automatic Fail-Safe Function.
Diagnostic programme to facilitate maintenance procedures.
Error management to facilitate troubleshooting.
Panel Mounting (DIN 43700).
Possibility of product customisation.
