Abstract (en)
[origin: US4518059A] The free end portion of the boom of a crane is detachably coupled to a flat rectangular carrier for a collapsible gallery. The carrier can pivot about an axis which is normal to the longitudinal direction of the boom to and from a position adjacent to one side of the boom, and the collapsed gallery can be pivoted to a position outwardly adjacent to the carrier when the latter is adjacent to one side of the boom. This renders it possible to move the crane without detaching the carrier and the gallery from the boom. The flat sections of the gallery are collapsible into planes which are parallel to the pivot axis between the gallery and the carrier.
