The lift control panel on an aerial device is an important element for effectively running the unit, enabling the working platform to be propelled into a desired location. Similar to how a steering wheel gives a truck-mounted aerial device mobility to get to and from a job site, the lift control panel gives the machine’s operators the ability to quickly and easily position the platform into the work area.
But because the operator control station is relatively small, it’s not always top of mind when new units are being spec’d. Given the importance of lift controls on aerial devices, however, following are some insights to consider when spec’ing them.
The foundation of every control panel is the ability for operators to use it to control the aerial device’s vertical longitudinal (or extend-and-retract) and rotational (or side-to-side) movements. For instance, most aerial device control stations are equipped with a single joystick. The joystick is designed to give operators control of the machine’s boom functions from one handle. “A common industry standard on an aerial device’s lift control panel is a three-function joystick,” said Dan Brenden, director of engineering for Terex Utilities (www.terex.com/utilities). “This type of joystick allows operators to move the individual booms up and down, as well as to rotate the unit.”
Four-function single joysticks are available as an option. This type of joystick enables operators to extend and retract the boom on articulating models, or it can operate elevator sections, if equipped, giving users even more control and functionality from one joystick. According to Brenden, “Terex uses similar single joystick designs across its entire aerial device product line, keeping uniformity within the brand, so from the smallest to largest machines, all controls function the same for the operator.”
