Abstract
A portable, self-contained telescoping camera tower system permits high angle imaging and rapid and smooth change of perspective. The camera tower is a stand-alone unit capable of being transported, set up and operated by a single individual and which provides steady advance and retreat of the tower over its full range of up and down movement. An arrangement of pulleys, bearing surfaces, and drive means, preferably with two power-up drives and a separate power-down drive, assures smooth operation though its full operating range
