This invention relates to an attachment for a fork lift. The attachment permits the fork lift to handle and invert a cylindrical drum of predetermined dimensions. The attachment includes a frame carrying pivot arms which pivot between first and second positions. Distal ends of the pivot arms carry rotating clamps which grip a drum and invert the drum. A clamp motion control mechanism is provided for selectively rotating the clamps and includes a dual piston pressure actuated cylinder. An over-center locking mechanism is provided for locking the pivot arms in a gripping position.
