Preliminary conditions:
– Load limiter correctly mounted and wired.
– Adjustment screws unscrewed to the maximum.
– Hook free of any load.
Equipment required:
– A load (called "WLL") equivalent to 100% of the
nominal capacity authorized for the lifting machine.
– An additional load equivalent to 10% of the "WLL".
– A load "X" equivalent to the value of the "Wire rope
slack" threshold.
