A clamping apparatus includes a frame and a pair of opposing clamping arms mounted on the frame for movement towards and away from each other to grasp or release a load. In one embodiment, each clamping arm defines a four-bar linkage which controls the angle with respect to the vertical of a contact portion of the clamping arm. The clamping apparatus may be mounted on a lift truck or other support member by a connector which permits the angle of the clamping apparatus with respect to the horizontal to be adjusted and which enables the clamping apparatus to pivot about an axis between a position in which it is disposed outboard of the axis and a position in which is it disposed forward of the axis.
