Your cable tie-downs are a necessary piece of equipment that can often break due to the forces acting on the cables inside a bin structure. Read below to see what to do when a cable tie-down breaks.
The cable tie down is the metal bracket and metal ring that is screwed to the bin floor, and then attached to the bottom of your cable with baler twine. The tie-down is engineered to be the point of failure on the cable "system" installed inside the bin, and can be no stronger than 25% of the tensile strength of the cable itself. Some forces that can break the cable tie down are: loading and unloading the bin, using a side draw to move the grain around, a bin sweep, etc.
If you find that your cable tie-downs are broken after you empty the bin you simply replace it with a new length of baler twine or something similar like fishing line that does not exceed 25% of the cable tensile strength. Your cable tie-downs breaking is a good thing and should be thought of like a seasonal maintenance activity. The tie-down breaking protects the cable itself from stretching, breaking, or damaging the bin roof/structure if pulled too much. Check your bins every time and replace the tie-downs as necessary.
Please see below a reference for the tie-down strengths and the different cable types associated with them.
