摘要
An ergonomic work station has upper and lower work platforms disposed one above the other. These are supported on electrically actuated telescoping pedestals to allow the user to select and adjust the elevation of the work platforms individually. Position sensors within each of the pedestals sense the elevation of the upper end of the respective pedestal and provide an output to logic and motor control circuitry. This is configured to maintain the lower work platform level when the height of the lower work platform is being adjusted and to prevent the upper and lower work platforms from colliding, by maintaining at least a predetermined minimum vertical distance between the two work platforms when the lower work platform is being raised or when the upper work platform is being lowered.
