LOAD CELL VERSION
The Niftylift HR12 is fitted with an electronic load cell. This load cell is a moment-independent design.
This means that independent of the load position inside the machine cage, the actual load is measured
and if pre-calibrated limit values are exceeded, warnings will be activated. If load exceeds the safe
working limit (SWL) of the machine, the machine will be disabled until the load is reduced to below
95% of the safe working limit. The design of the unit meets the requirements of both BS EN 280 and
ISO 13849 with a safety integrity level of "Category 3 PL d. (Refer to Appendix A)
The current load in the cage is displayed on the digital display unit as a percentage of SWL. Please
refer to Section 4.3.2.
4.5.2
CALIBRATION, INSPECTION AND MAINTENANCE

adjusted, repaired or inspected by the operator
.
All enquiries relating to calibration, inspection or maintenance should be directed to Niftylift or one of
