Abstract
A trolley for traversing a zip line includes a first load-bearing sheave rotatably mounted to one or more side plates, and a second load-bearing sheave rotatably mounted to the one or more side plates and rearward of the first sheave. The trolley also includes an anchor point on the trolley for attaching a payload. When the trolley decelerates, forces acting on the payload create a downward load on the first sheave and the second sheave.
