Abstract
An apparatus for handling a large-sized article such as a window assembly for a car has a carriage movable three-dimensionally in X-, Y- and Z-directions, and a vacuum holding device tiltably and fixably secured to the carriage. This apparatus conveys the article to a remote place and holds it while it is being secured to an object such as the wall of a car, thus improving the efficiency and safety of the work.

An apparatus for handling a large-sized article comprising:
- a mobile truck;
- a support structure which is mounted on said mobile truck;
- a traversing device which is movably mounted on said support structure for lateral movement;
- a lifting device which is movably mounted on said traversing device for vertical movement independently of the lateral movement;
- a carriage movably mounted on said lifting device for fore and aft movement independently of the lateral and vertical movements;
- a bracket having suction cups mounted thereon;
- a universal joint which is secured to said bracket;
- and
- a fixing device to which said bracket is rotatably connected by said universal joint for fixing and releasing the rotation of said bracket with respect to said fixing device, said fixing device being pivotably mounted on said carriage so as to be able to rotate between a first position in which said suction cups on said bracket can be brought into contact with an object of said mobile truck and a second position in which said bracket is substantially parallel to a desired position to which the object is to be moved.
