Zip line
open-in-new
<p>A zip-line, zip line, zip-wire, flying fox, or death slide is a <a href="/facts/Pulley/Mrq15sdg">pulley</a> suspended on a <a href="/facts/Wire_rope/9z4b9SYB">cable</a>, usually made of <a href="/facts/Stainless_steel/IDdo8bEx">stainless steel</a>, mounted on a <a href="/facts/Slope/a2L3k0j5">slope</a>. It is designed to enable <a href="/facts/Cargo/0aDk22Yl">cargo</a> or a person propelled by <a href="/facts/Gravity/bqAN7DdQ">gravity</a> to travel from the top to the bottom of the inclined cable by holding on to, or being attached to, the freely moving pulley. It has been described as essentially a <a href="/facts/Tyrolean_traverse/BwUmwC2I">Tyrolean traverse</a> that engages gravity to assist its speed of movement. Its use is not confined to adventure sport, recreation, or tourism, although modern-day usage tends to favor those meanings. </p>
