Abstract:
1. A method for automatically leveling a mobile aerial work platform apparatus comprising the steps of: providing a mobile aerial work platform apparatus including a mobile base, a movable platform, a lift mechanism configured to move the platform in a substantially vertical direction with respect to the mobile base, a stabilizing assembly including at least one outrigger leg mounted on the mobile base, a plurality of sensors configured to sense an orientation of the mobile base and a condition of the at least one outrigger leg, and a control assembly in communication with the plurality of sensors, receiving by the control assembly a command from an operator to automatically level an orientation of the mobile base of the apparatus, and automatically adjusting the stabilizing assembly so that an orientation of the mobile base is substantially level, wherein the control assembly is configured to receive input from the sensors and sends output to the stabilizing assembly to perform the automatic adjustment; detecting if the movable platform is in a lowermost position, and preventing the base frame from being automatically leveled if the movable platform is not in the lowermost position.
