A: Ziplines use different types of braking systems depending on the braking angle and braking speed. Combinations of a pulley, redirect, hand braking, and spring brakes are often used. No Skyline builds use hand braking methods, and we err towards using a 2:1 spring brake system with a redirect rope. This places a catch block at the start of the braking system, with a rope anchored to the installed spring brakes to dissipate force and ensure the smoothest, safest braking experience possible.
