ABSTRACT:
A vehicle mounted aerial tower in which a primary fixed length boom is mounted pivotably from one end and extends longitudinally outwardly of the vehicle, being elevated about the pivot by a lift cylinder which is connected to the vehicle and to the boom and having mounted pivotally from the outer end of the boom a carriage assembly which supports a secondary elongated boom for pivotal movement with the carriage and actuatable lengthwise of the primary boom by sprocket and chain means, or the like, and a personnel work platform or cab pivotally supported from the outer end of the secondary boom and adapted to be maintained in a predetermined position relative to vehicle ground support. The combination of available movements of elevation of the secondary boom with the primary boom, of lengthwise actuation of the secondary boom in relation to the primary boom, and of pivotal movement of the secondary boom from the front end of the primary boom enables the personnel cab to be actuated to a variety of locations relative to the vehicle from a position well below ground level to a long forward reach position to a position of relatively high elevation.
