Have a Kone hydro with this operator that seems to go through quite a bit of cable recently. I know its a eighth inch aircraft cable, but is there a special strand configuration due to the tight bends on the small drum? We have used some standard 7X19 cable and it seems it doesn't last long before it starts to fray. Sheaves and drum both look fine as far as any burs or damage to the grooves. Any insight would be appreciated.
