Abstract
A ladder rack adapted to be affixed to the roof of a utility vehicle is equipped with a DC motor powered drive which, when actuated, controls the movement of ladders from a location on the vehicle roof to a location alongside the body of the vehicle. The drive includes a DC motor driven lead screw having a traveling nut thereon coupled to an endless chain deployed about a sprocket on an output shaft and a sprocket on an idler shaft such that rotation of the lead screw drives the output shaft. That output shaft is, in turn, coupled to a connecting rod of the ladder rack.
