Abstract
An articulated aerial lift has a platform that is coupled to one end of a boom. The other end of the boom is connected to an upper end of a riser. An arm couples the lower end of the riser to a turret. As the arm moves between a lowermost position to a raised position, the riser rotates between a forward position to a backward position in order to reduce an overturning moment caused by the platform. Rotation of the riser can be accomplished with nonparallel arms.
