Abstract

An aerial lift is provided which includes a stowable jib boom and a stowable work platform. The stowable jib boom may be stowed at one side of the main boom and the work platform may be stowed at the other side of the main boom. The jib boom is easily brought into position through the use of a mounting apparatus on the outer end of the innermost boom section of the boom assembly. The work platform may also be moved between its stowed and working positions through the use of the mounting apparatus on the outer end of the inner boom section.

Claims

1. An aerial lift, comprising:

a self-propelled vehicle having forward and rearward ends;

a pedestal rotatably mounted, about a vertical axis, on said vehicle;

a telescoping boom structure including an elongated outer boom section with at least one elongated inner boom section telescopically received thereby;

said outer boom section having first and second sides, an inner end and an outer end;

said inner boom section having an inner end and an outer end;

a first mounting apparatus on said outer end of said inner boom section;

said first mounting apparatus being pivotally movable, about a first horizontal axis transverse to the longitudinal axis of said inner boom section;

said first mounting apparatus also being pivotally movable about a second axis which is disposed transversely with respect to said first axis;

a first work platform adapted to be selectively removably secured to said first mounting apparatus for movement therewith;

an elongated jib boom, having inner and outer ends, adapted to be selectively removably positioned and secured in a stowed position at said first side of said outer boom with said inner end thereof being positioned adjacent said outer end of said outer boom section and said outer end of said jib boom being positioned forwardly of said inner end thereof when in the stowed position;

said inner end of said jib boom adapted to be selectively secured to said first mounting apparatus;

said first mounting apparatus being selectively movable with respect to said inner boom section when said first work platform is secured thereto to permit said first work platform to be positioned at said second side of said outer boom section so that said first work platform may be disconnected from said first mounting apparatus, moved towards said inner end of said outer boom section, and stowed at said second side of said outer boom section;

said first mounting apparatus also being selectively movable with respect to said inner boom section when said first work platform is disconnected from said first mounting apparatus to permit said first mounting apparatus to be positioned adjacent said inner end of said jib boom, when in its stowed position, for connection therewith so that said jib boom may be pivotally moved from its stowed position so as to be extended from said outer end of said inner boom section.

2. The aerial lift of claim 1 wherein said outer end of said jib boom has structure associated therewith for connection to a second work platform.

3. The aerial lift of claim 1 wherein said jib boom is tubular and wherein said first mounting apparatus includes a tubular member projecting therefrom which is receivable by said inner end of said jib boom.
