Abstract:
1. A braking system for a zip line comprising: a braking carriage on a zip line; said braking carriage is connected to a flexible leader; said flexible leader extends to links of chain and into an angled length of pipe that is angled from horizontal at an angle greater than a static coefficient of friction of said links of chain on said angled length of pipe and then into a collecting reservoir to a progressive load of links of chain wherein said progressive load is created by moving sequentially more weights that are resting within said collecting reservoir to said angled length of pipe and out of said angled length of pipe; an initial load is determined by initial links of chain that are displaced from said collecting reservoir; said progressive load is determined by a sum of said initial links of chain that are displaced from said collecting reservoir and by all additional links of chain that are displaced from said collecting reservoir; whereby when said braking carriage is moved along said zip line said progressive load increases with each said lifted sequential weight to provide braking of said braking carriage.
