ABSTRACT:
A clamping apparatus for use on a material handling machine. The clamping apparatus includes a mounting bracket which is fixed to the material handling element of the machine, a connecting bracket which is pivotally mounted on the mounting bracket and a clamping arm which is pivotally mounted on the connecting bracket. The connecting bracket is pivotally mounted on the mounting bracket between an active position and a storage position. When the connecting bracket is in the active position, the clamp arm is hydraulically actuated within a vertical plane between an upper non-clamping position and a lower clamping position. When the connecting bracket is in the storage position, the clamp arm extends horizontally in an out of the way position. The connecting bracket is maintained in the active position by first retaining means and in the storage position by second retaining means.
