| 20120248804 | Gripping Method for Turbocharger Housing - A gripping method for a turbocharger housing used to process a turbocharger housing formed by casting, includes a scroll formed in a spiral shape from an axial center, and a large diameter hole and a small diameter hole provided along an axial direction of the scroll with space therebetween, such as to face each other. After positioning of the turbocharger housing is performed using an end surface of the large diameter hole facing the small diameter hole as a reference surface for positioning in the axial direction, an inner diameter of the large diameter hole is gripped. | 10-04-2012 |
| 20130168984 | INTERNAL PIPE GRIPPING TOOL - An internal pipe gripping tool includes a tool body adapted for insertion into a pipe. A gripper is disposed adjacent and movably coupled to the tool body. The gripper has an engaged position and a released position relative to the tool body. A lever has a first end node, a second end node, and an intermediate node between the first and second end nodes. The first end node is coupled to the tool body, and the intermediate node is coupled to the gripper. A force applied to the second end node results in another force at the intermediate node that shifts the gripper from the engaged position to the released position. | 07-04-2013 |

| 20090184529 | Pipe pulling assembly - A pipe pulling assembly ( | 07-23-2009 |
| 20090230706 | MECHANICAL DEVICE FOR GRIPPING THE INSIDE OF HOLLOW OR BORED BODIES - This invention concerns a device for gripping the inside of hollow or bored items, that comprises a prehensile device ( | 09-17-2009 |
| 20130270849 | LIFTING APPARATUS AND METHOD OF USE - The present invention is a lifting apparatus that includes a master wedge bar, a slave wedge bar, a cam lug and a handle. The master wedge bar and slave wedge bar are configured to be placed in a drilled core in an object to be lifted. The cam lug is pivotally coupled to the master wedge bar and drivingly engages with the slave wedge bar such that upward force applied to a lift end of the cam lug drives the slave wedge downward. The master wedge bar and the slave wedge bar generate an outward force upon the core wall of the object upon the downward movement of the slave wedge bar relative to the master wedge bar such that the apparatus engages the core wall and secures itself in it by friction. A handle is configured to disengage the apparatus from the core wall when lifted upward. | 10-17-2013 |

| 20090295179 | TIRE LIFTING MECHANISM - A tire lifting mechanism is disclosed. The tire lifting mechanism includes a frame having a lower plate and a spaced apart upper plate assembly with at least one tube disposed therebetween. A plurality of extendable arms is pivotally attached to the frame. A movable plate and cooperating screw mechanism is provided to move the arms to and from an extended position to engage an associated tire adjacent a bead area thereof. An upward movement of the frame in respect of a supporting surface causes the tire to be centered and lifted from the supporting surface and suspended from the arms of the lifting mechanism. | 12-03-2009 |

| 20120098284 | FOLDING REACH EXTENDER - A tool configured to grasp objects, and to expand and/or retract while holding the objects is disclosed herein. The tool can include a pair of handles disposed on a first end of an expandable assembly, such as a scissor like assembly. The pair of handles can be adapted to expand the expandable assembly when they are moved towards one another and retract the expandable assembly when they are moved away from one another. A gear assembly can be disposed on a second end of the expandable assembly. The tool can allow users to reach, grasp, move, and release remote objects. | 04-26-2012 |
| 20120306224 | Vault Cover Mover - A vault cover grabber, bolt cover lifter or vault cover eye-hook is formed from two L shaped components with each component having an eye opening on one end and each component having an L shaped end (lower end) designed to be inserted through a void of a vault cover or other object. The top ends or eye ends of the two components are pivoted apart to allow the two lower ends to pass through a vault cover void. After insertion, the upper eye ends are pivoted together, causing the two lower ends to contain the vault cover. A hook or other object is placed through the two eye voids of the top ends of the two components. A combination of double clevis connectors, shaft collars, shackles and chains secure the vault cover grabber to a handle or other means of lifting. | 12-06-2012 |
| 20150123415 | GRIPPER - The invention relates to a gripper for raising and lowering loads and having the following configuration:—it comprises a coupling part and a connecting part,—the connecting part is guided on the coupling part for movement along a movement axis between a first end position and a second end position, wherein those ends of the aforementioned parts which are oriented away from one another are further apart from one another in the first end position than in the second end position,—at least two catch elements are present on the coupling part and can be moved between a gripping position, in which they use a rear-engagement surface to engage behind a mating element of the load, and a release position, in which they release the mating element,—the connecting part is connected to the at least two catch elements via at least one gear mechanism. | 05-07-2015 |
