ABSTRACT:
A truck mounted telescopic boom structure including a stowable jib boom having a stowable personnel basket mounted thereon is described. A mounting structure is provided at the outer end of the innermost boom section of the boom structure and includes means for pivotally moving a work platform or basket between operative and stowed positions. When the boom structure and the jib boom are in their stowed positions, the personnel basket is positioned closely adjacent the jib boom at one side thereof so as to be within the highway width restrictions. The instant invention enables the personnel basket to be connected to the outer end of the jib boom at all times without the necessity of removing the personnel basket from the jib boom when the jib boom and the boom structure are in their stowed positions.
