ABSTRACT:
A vehicular low profile, self propelled aerial work platform having an articulated parallelogram boom assembly including a lower boom assembly having pairs of compression and tension arms pivotally connected between a support frame on the vehicle and a floating frame, and an upper boom assembly having pairs of compression and tension arms pivotally connected between the floating frame and a riser connected to the proximate end of a telescopic boom assembly having a work platform connected to the distal end thereof. The ends of the tension arms in the upper and lower boom assemblies which are pivotally connected to the floating frame, share the same pivot connection so that when the articulated parallelogram is in the folded position the tension arms are inter-digitated and lie in the same common plane so that the vehicle can be maneuvered through a low doorway, in the order of six feet, seven inches. A synchronization linkage is mounted in the floating frame and connected between the pairs of compression arms in the upper and lower boom assemblies for maintaining the floating frame in a vertical orientation during the elevating and folding of the articulated parallelogram boom assembly.
