Abstract
A compound frame to support a plurality of sheaves on a tower of an aerial tram with a predetermined bias between each sheave and a supported transiting cable. The sheaves are supported in paired opposed groups with each sheave of a group in substantial opposition so that the bias of each group of sheaves provides a safety factor to aid in maintaining a transiting cable therebetween. The manner of biasing paired sheave groups requires minimal forces for greater economy. An associated desheavement annunciating system is disclosed.
