Abstract
A synchronization device for an articulated parallelogram boom assembly having a floating frame connected between an upper work platform carrying boom assembly, and a lower vehicle mounted boom assembly. The synchronization device is mounted on the floating frame and includes a slidable member and compression and tension links connected between the slidable member and the upper and lower boom assemblies. The synchronization device is constructed and arranged to maintain the included angles of the adjacent upper and lower boom assemblies substantially identical during the luffing movement of the boom assemblies so that the work platform is maintained parallel to the ground plane.
