Abstract: An aerial device system includes an adjustable railing and a coupler. The adjustable railing is positionable around at least a portion of a base platform and is movable between a stowed position and a deployed position. A height of the adjustable railing in the deployed position is greater than a height of the adjustable railing in the stowed position. The coupler is communicatively coupled to the adjustable railing and is configured to detect a position of a component of an aerial device of the aerial device system and move the adjustable railing based on the detected position of the component of the aerial device. A method of controlling a cab guard safety system for the aerial device includes detecting the position of the component and moving the adjustable railing to a stowed position or a deployed position based on the detected position of the component.
