ABSTRACT:
An apparatus for lifting a cylindrical barrel includes a first arm having a lifting frame at one end and a chime gripping arch at the other end. A second arm is pivotally connected at one end thereof to the lifting frame and includes a second chime gripping arch at its other end. During operation, the chime gripping arches are placed on the barrel outer surface just under the barrel chime and by lifting the lifting frame, the two chime gripping arches are forced toward one another and against the barrel surface just under the chime. A locking arm is pivotally connected to the first arm and is selectively pivotable for engaging the second arm and creating a locking triangle. The locking arm effectively, selectively locks the first and second arms with respect to each other preventing radial movement thereof and preventing movement of the chime gripping arches away from the barrel.
