ABSTRACT:
An aerial platform attachment for a crane having an extensible boom including a basket pivotally suspended from the boom tip. A loop on the bucket is engaged by a projection secured to the boom when the bucket is pivoted adjacent the boom and the boom is then fully retracted. A brake which is applied by a hand lever movable in either direction from a central release position locks the bucket relative to the boom when in a working position.
