The connecting device comprises: first members for, during picking up or putting down of the stack, moving a support element freely relative to the lifting member through an at least small distance relative to the lifting member in substantially vertical, upward direction; second members for freely rotating a support element through an at least small angle about an axis perpendicular to the vertical plane, the second members allowing free rotation only when, during picking up or putting down of the stack, the support element has been moved upwardly.Type: GrantFiled: December 11, 2001Date of Patent: January 7, 2003Assignee: FPS Food Processing Systems B.V.Inventors: Johannes Aloysius M. Peters, Freerk Dirk Slagman, Adrianus van Pinxteren

Patent number: 6416099Abstract: A tool for lifting and rotating an object having a center of gravity is provided. The tool includes a first rail, which is adapted to be coupled to a first end of the object, and a second rail, which is adapted to be coupled to a second end of the object. Inversion linkage is coupled to the first rail and to the second rail. The inversion linkage includes a pivot pin that automatically moves into coincidence with the center of gravity of the object when the first rail is coupled to the first end of the object and the second rail is coupled to the second end of the object.Type: GrantFiled: November 30, 2000Date of Patent: July 9, 2002Assignee: ABB Technology AGInventor: Frank Ward James, Jr.

Publication number: 20020050724Abstract: Articulated lifting device includes a generally orthogonal support frame having a forwardly extending adjustable lifting arm inserted through a sleeve at the top end of a downwardly extending telescopic leg, a plurality of interchangeable load adapters having elongated adapter arms and a connector that connects telescopic leg with any of the load adapters. The connector may be locked to create rigid frame connection or may be unlocked to allow pivotal movement of the connector in relation to the telescopic leg. An adjustable counterweight may be attached to free end of the adapter arm to balance weight of the heavy adapters. The lifting arm has a hookup point in order to suspend the lifting device off a crane or a hoist. The load adapters may thereby be attached to parts of machinery or other loads located under overhanging structures in order to remove or replace thereof.Type: ApplicationFiled: October 30, 2001Publication date: May 2, 2002Inventor: Valery Tsimmerman

Patent number: 6357810Abstract: A hoist assembly 10 for lifting an object 12 includes a support fixture 14 having three elongated support rails or members 16, 18, and 20, a movable lever assembly 24, which is mounted upon a spanning member 22, and three interconnecting chains, members or assemblies 26, 28, and 30 which are coupled to fixture 14 and to object 12. Movable lever assembly 24 moves from a first position to a second position when object 12 is lifted, thereby shifting the center of gravity 142 of the fixture 14 and allowing fixture 14 and object 12 to remain in a level or horizontal position.Type: GrantFiled: January 14, 2000Date of Patent: March 19, 2002Assignee: Ford Global Technologies, Inc.Inventor: Kyle E. Schwulst

Patent number: 6354644Abstract: Apparatus for handling hollow core rolls of different core diameters, by picking up a roll disposed with its axis vertical, relating the same to a horizontal position, and sliding it onto a horizontally extending spindle. A stepped diameter holder having sets of gripper elements is supported on an angled arm driven by a rotary actuator. After insertion of the stepped diameter into a roll core and outward movement of the gripper elements, the core can be moved to a horizontal orientation by oscillation of the actuator. The stepped diameter holder has a ball locking assembly which is inserted into a receptacle attached to the projecting end of the spindle. After full insertion sensed by blockage of air flow out of a hole in the end of an actuator rod caused by contact with a compressible insert, the actuator rod is moved axially to dock the spindle to the stepped holder by operation of the ball locking assembly and the gripper elements are released, allowing powered push off of the roll onto the spindle.Type: GrantFiled: April 24, 2000Date of Patent: March 12, 2002Inventors: James Zaguroli, Jr., Steven R. Sowter

Patent number: 6322117Abstract: Lifting tools for safe, 105 degree, off-center rotation of large, heavy objects are disclosed. A lifting tool includes a bar that can be positioned generally parallel to a centerline of the object, and first and second clamps that are rotatably or slidably coupled to first and second ends of the bar, respectively. The clamps are adapted to secure the tool to edges of the object. The tool also includes a pivot arm that is rotatably coupled to the bar, which allows the object to be lifted, rotated up to 90 degrees, moved, and then set down. The pivot arm includes first and second chain sprockets disposed along a length thereof. A second pair of chain sprockets is coupled to the second chain sprocket via a common shaft. A pair of chain segments are attached to the pivot arm, and engage each of the second pair of chain sprockets.Type: GrantFiled: December 28, 1999Date of Patent: November 27, 2001Assignee: ABB T&D Technology Ltd.Inventor: Frank Ward James, Jr.
