Zipline Diameter Pulley Friction/ Rolling Resistance

Click For Summary
SUMMARY

The discussion centers on the impact of cable diameter on zipline performance, specifically comparing 7/16" Stainless Steel Cable to 3/8" cable. The consensus indicates that switching to 3/8" cable may not significantly enhance ride speed or reduce noise, as the primary source of noise is likely the pulley bearing rather than the cable's surface area. Participants emphasize examining the pulley contour to understand contact area differences, which may influence friction levels.

My zipline is 200 feet long built with 7/16" Stainless Steel Cable. Would 3/8" cable result in a faster ride with less noise from the trolley due to significantly less surface area for friction?

Look at the contour of your pulley to see exactly what difference in contact area will result.

My initial reaction is to say that this will not make a lot of difference because I suspect that the noise is generated in the pulley bearing, and that would not be affected by changing the cable.
