ABSTRACT:
An apparatus controllably moves the forks of a material handling vehicle in traverse directions relative to a carriage assembly. The carriage assembly includes fork position sensors which detect the transverse location of each fork. A controller receives signals from the position sensors and moves the forks to locations a preselected or calculated distance apart. Forktip sensors detect the opening in a load during movement of the forks. The controller receives signals from the forktip sensors and positions the forks such that they are disposable within the load opening. The apparatus is especially suitable for use on an Automatic Guided Vehicle (AGV).
