BOOM ARTICULATION MECHANISM WITH SIMULTANEOUSLY OPERABLE CYLINDERS ABSTRACT A boom articulation mechanism for interconnecting and displacing a pair of boom members. The mechanism comprises a connector link having a pair of opposed external boom pivot connections. Each of the booms has a pivot end connected spaced apart to a respective one of the external pivot connections. The connector link also has a pair of internal cylinder pivot connections spaced apart closer than the external pivot connections. The external boom pivot connections and the internal cylinder pivot connections are disposed on parallel axes spaced apart a distance not greater than the distance between the external boom pivot connections less the distance between the cylinder pivot connections. A first hydraulic cylinder is pivotally connected at one end to a first of the booms, and has a piston rod end connected to an associated one of the internal cylinder pivot connections. A second hydraulic cylinder is pivotally connected at one end to a second of the booms, and has a piston rod end connected to an associated one of the internal cylinder pivot connections. The cylinders and the booms are disposed in the same plane. A hydraulic circuit is provided for simultaneous synchronized operation of the cylinders to articulate one of the booms relative to the other along a common arc.
