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.

Abstract: In an aerial lift having a lower boom, an upper boom, and a personnel carrier bucket attached to the upper boom, with the upper boom having an overcenter capability, wherein the upper boom can pivot from a folded position in a non-overcenter zone of operation past a center position and into an overcenter zone of operation, there is provided a control handle arrangement with first and second handles having control movements such that, when the operator is correctly positioned, the direction the bucket moves corresponds to the direction the respective handle moves for all zones of operation.
