AWLFN2 Rope Tension Load Cell

Rope tension loadcell AWLFN2

Specially designed for protecting cranes from overload and for measuring the tension of wire ropes. In many industrial applications the tension in were rope needs to be carefully and continuously monitored. Usually load cells are placed in series with the rope, either at a point along its length or more commonly between the end of the rope and the fixture. The problem is that such a load cell is best suited to new applications where it is designed in at an early stage.

Safety note:
It is essential to provide additional safety precautions like safety chains etc. for catching the load in a breakage, which cannot be excluded completely.
