Abstract
An elevating platform assembly comprises a pair of laterally spaced, generally vertical masts and an elongated working platform extending generally horizontally between the masts. Hoist mechanisms act between the ends of the working platform the masts and are actuable to move the working platform along the masts to different elevations. At least one level sensor is provided on the working platform and detects when the working platform deviates from a generally horizontal orientation. At least one controller is responsive to the at least one level sensor and controls the hoist mechanisms to adjust movement of the working platform when the working platform deviates from the generally horizontal orientation thereby to return the working platform to the generally horizontal orientation.
