Abstract
A sheave bracket directs a trailing cable of a mining vehicle. The bracket is hingedly secured to the vehicle and includes a plate and a plurality of sheaves coupled to and extending from the plate. The sheaves are arranged to guide the cable. The sheave bracket also includes a force control mechanism movable between two positions to adjust tension in the cable. The force control mechanism dampens strain in the cable when the direction of the bracket is changed.
