ABSTRACT:
Apparatus for releasably securing a materials handler to a boom while permitting rotation of the materials handler about relatively perpendicular first and second axes. A first connector system includes a member attached to a hitch extending along the second axis and having a tapered nose arranged to engage an aperture in an upwardly projecting member attached to the materials handler. A second connector system includes a recess in one of the hitch and handler having axially aligned apertures through opposite walls thereof and a projection defined by the other of the hitch and handler arranged to fit within the recess. An arm attached to the hitch for rotation relative thereto about the second axis projects towards and engages cooperating structure on the materials handler so that rotation of the arm causes the materials handler to rotate relative to the hitch about the second axis.
