Hi Guys,
We need to design a small electrically operated unit to clamp and unclamp onto 12 or 14mm diameter 7/19 IWRC stainless steel cable and act as an emergency stop. The unit will need to be clamped and repositionned at the same point on the cable many times a day so we must not fatigue the cable. I have been unable to locate any calculations for the clamping force required on a cable to achieve a certain axial SWL. Does any body have any experience in how much clamping stress can be applied to the cable with out long term damage and a frormula for the axial load capability for this force as I understand in practice it is not just force x coeficient of friction. Our cable supplier has been unable to help.
Thanks
Kevin
