An overload limiter does not increase crane capacity. It is a protective function intended to warn or restrict defined motions at configured thresholds. Sensor type, mechanical installation, wiring, display and control outputs should be reviewed as one system.
A controlled test plan may include zero verification, a known reference load, alarm thresholds, restriction of the lifting direction, permitted safe-lowering behaviour and fault response. Setpoints must not be changed arbitrarily and should be verified against equipment design, manufacturer information and applicable requirements.
Records should identify the crane, date, reference method, results, adjustments and responsible personnel. Testing requires a controlled area, suitable equipment and competent personnel.
This content supports preliminary review. Equipment selection, structural calculations, compliance and commissioning decisions must be verified using site data and competent engineering.
