said carriage frame connected to said main frame for pivotable movement of said carriage frame about a generally horizontal first axis relative to said main frame and said attachment means, said first axis generally transverse to said forks upon attachment of said frame to said forks;
said object engaging member pivotally connected to said carriage member for pivotable movement about a second axis of rotation generally perpendicular to said first axis, said object engaging member secured to said carriage member for pivotal movement therewith about said first axis as said carriage member pivots about said first axis;
said object engaging member including first and second clamps mounted on said member and moveable between an open position and a closed position, said clamps in said open position spaced apart a distance sufficient to receive an object of predetermined dimensions, said clamps in said closed position spaced apart a distance sufficient to grasp said object;
motive power means including a first actuator for operably moving said carriage frame about said first axis, said motive power means further including a second actuator for operably moving said object engaging member about said second axis and said motive power means still further including a third actuator for moving said clamps between said open and closed positions at an option of an operator, said motive power means carried on said attachment and independent of a power source of said forklift; and
said second and third actuators secured to said carriage frame for movement therewith about said first axis, said first actuator secured to said main frame for movement therewith.
