Abstract: The present disclosure relates, according to some embodiments, to roll lifting assemblies, systems, and methods for lifting, handling, and/or maneuvering rolled material. According to some embodiments, a roll lifting system may be configured to move a single roll and/or to concurrently move two or more rolls. For example, a roll lifting system may comprise a translocation apparatus and/or a lift assembly.

Abstract: A gripper mechanism for moving an object having a surface cavity, the gripper mechanism comprising an actuation end moveable in an axial direction and a rotary body. A first mechanism is configured such that movement of the actuation end in an axial direction rotates the rotary body. A gripper is moveable between an engaged position and a disengaged position. In the engaged position the gripper is capable of engaging an object and in the disengaged position the gripper is capable of being received into and removed from a cavity of an object. The gripper is connected to the rotary body by a second mechanism. The second mechanism is configured such that rotary motion of the body moves the gripper between the engaged position and the disengaged position.

Abstract: Disclosed is multiple-unit indexing, mechanical scissor clamp for handling one or more modular segmental retaining wall units, also called “SRW blocks” having opposite ends each provided with a vertical groove. This clamp allows the user to move SRW blocks from a shipping pallet to a wall. The clamp and blocks are lifted using traditional construction machinery such as a backhoe, crane, bobcat, etc. The significant innovation of this clamp/block system is the ability to lift and place more than one large segmental retaining wall block with each installation cycle, substantially increasing installation efficiency.

Abstract: A gripping device for automatic bottle-topping machines comprising an anti-rotation blocking element, mobile between an opening position and a gripping position, a first mechanism, provided for actuation of the anti-rotation blocking element, a first actuation element, operatively connected to the first mechanism a gripping element, mobile between an opening position and a gripping position, a second mechanism, provided for actuation of the gripping element, and a second actuation element, operatively connected to the second mechanism, wherein the anti-rotation blocking element and the gripping element are provided for engaging on a bottle.

Abstract: It is an object to provide an aligner for centering a wafer and adjusting an angle of a notch or the like of the wafer while gripping edges of the wafer capable of attaining a shortened takt time and miniaturization of the apparatus by employing a mechanism capable of infinite rotation without being restricted by a rotational range, by eliminating cables and/or tubes at the rotating portion. The link mechanism for causing opening and closing movements of the gripping mechanism for gripping a wafer 1 is supported via a bearing 14 with respect to the link mechanism driving portion for driving the link mechanism so that only the gripping portion and the link mechanism can be rotated.

Abstract: A grapple 1 comprises a sleeve 8 moveable along a shaft 12. The sleeve 7 is joined to an upper attachment 6 for receiving the long-line of a crane, and the shaft 12 is joined to a pivot attachment 13. The sleeve 7 and the pivot attachment 13 are joined to jaws 2 and 3 which can move in a scissor-like fashion. Pushing down on the sleeve 7 causes a rider 9, forming part of a catch rod 8, to move into a series of stepped channels in a block 14 associated with the shaft 12. The rider 9 can be positioned in the channels to lock the jaws 2 and 3 open, and can be subsequently removed from the channels to enable the jaws 2 and 3 to close towards one another.

Abstract: A frame having upper and lower longitudinal frame members supports pairs of pivotally connected holding arms having curved “J-shaped” distal ends and curved blades mounted thereinbetween. Latch arms pivotally connect to one another on one end and to a short upper frame member and a short lower frame member of the longitudinal frame members support a disassemble cylindrical cam latch and lock assembly mounted onto the upper latch arm. A travel pin moves up and down within a predetermined channel or groove formed in a solid one piece cast cylindrical bushing and rotates in a predetermined pattern to simultaneously rotate and move a locking dog and a wedge shaped plunger extending downwardly therefrom up and down and in for cooperative engagement with a slot or keyhole formed in the lower latch arm thereby engaging or disengaging the “J-shaped” holding arms.
