A color coding indicating the amount of boom extension is provided on the fly section of the boom, visible to the workman in the platform, and an indicator plate having corresponding color coding is provided adjacent the controls on the platform. A Bowden cable is connected to the indicator plate and the fly section, to move the indicator plate proportionately to the angle of the boom to the horizontal.
