Patent number: 10207902Abstract: Exemplary embodiments of a load-mountable lift eye assembly comprise a connection interface, a mounting coupler and an axial retention element. A bushing may be disposed radially between the mounting coupler and a mounting bore of the connection interface. The axial retention element may engage the mounting bore so as to retain a segment of a head portion of the mounting coupler between a shoulder flange of the mounting bore and the axial retention element, thereby retaining the mounting coupler in mounting position and limiting its ability to move axially with respect to the connection interface. The mounting coupler may include a head-shaft interface. In such case, when the mounting coupler is in its mounting position, the head-shaft interface may be axially offset from the mounting face of the connection interface. The mounting coupler may include a tool-engagement section adapted to be engaged by one or more types of torqueing tools.Type: GrantFiled: November 27, 2017Date of Patent: February 19, 2019Assignee: MJT Holdings, LLCInventors: Benjie Bradshaw, Patrick Lawrence Giles

Patent number: 9254987Abstract: A mounting tool for use in safely lifting a heavy object such as a wind tower segment. Mounting tools may be provided in a kit that includes a tool that is especially adapted for attachment to the top of the object, and a tool that is especially adapted for attachment to the bottom of the object. Both the top and bottom mounting tools include a mounting bracket for removably mounting the tool to a mounting ring on a heavy object. To accommodate different bolt patterns in mating holes in the objects, the mounting bracket has a slotted mounting hole and two generally annular mounting holes extending therethrough. These mounting holes are arrayed along a common axis. A hoist ring assembly is mounted to the mounting bracket and includes a bail adapted for swiveling and pivoting movement to define a generally hemispheric envelope.Type: GrantFiled: August 27, 2013Date of Patent: February 9, 2016Assignee: MJT Holdings, LLCInventor: Tony J.

Publication number: 20140327262Abstract: In an omni-positional hoist ring assembly, a U-bar is pivotally mounted to a body, and a mounting member is threadably mountable to a load. The body is mounted to swivel about the mounting member, and includes a detent engaging bore. The mounting member includes a threaded stud or threaded female connector, and a head engagable by a torque-applying tool. A latching assembly is adapted to axially releasably retain the body to the mounting member, and includes a detent and a C-washer. The C-washer is pivotally mounted to the body and has a threaded detent retaining bore. The detent has a male detent thread engaged with the threaded detent retaining bore for holding the detent in engagement with the C-washer. The detent includes a plunger which is spring biased to reversibly urge a body engaging member into engagement with the detent engaging bore.Type: ApplicationFiled: May 2, 2014Publication date: November 6, 2014Applicant: MJT HOLDINGS, LLCInventor: Tony J.

Patent number: 8596701Abstract: A hoist ring assembly with expansion anchor includes an anchor subassembly and a rotatable and pivotable lifting loop. The anchor subassembly includes a bushing element, an engagement element and a retainer element. The bushing element has an anchor shaft extending along a major axis. The engagement element has a threaded bore extending long a bore axis which is approximately parallel to the major axis when the assembly is in assembled state. The threaded bore is adapted to threadably receive a threaded portion of the retainer element. The bore axis may be forced out of alignment with the major axis by way of a tightening rotation of the threaded portion with respect to the threaded bore, thus expanding the effective diameter of the combined anchor shaft and engagement element. The assembly is thereby releasably anchorable to a pre-drilled hole in a load to be lifted.Type: GrantFiled: June 1, 2012Date of Patent: December 3, 2013Assignee: MJT Holdings LLCInventor: Tony J.

Patent number: 8388034Abstract: A lift stub with an elongated shaft member that has a longitudinal axis, a proximal end and a distal end. A lift eye element is spaced laterally by a lateral distance from the longitudinal axis, a first distance from the proximal end, and a second distance from the distal end. The lift eye element pivotally mounts a clevis member to the elongated shaft member for rotation about a clevis axis that extends generally normal to the longitudinal axis of the elongated shaft member. The clevis has a throat that is adapted to receiving a lifting hook therein. A foot portion extends from the distal end towards the proximal end for a third distance, which is approximately less than the second distance. A spur element projects generally laterally of the elongated shaft member adjacent the distal end and generally laterally opposed to the lift eye element.Type: GrantFiled: July 19, 2011Date of Patent: March 5, 2013Assignee: MJT Holdings LLCInventor: Tony J.

Patent number: 8201867Abstract: An omni-positional hoist ring assembly including a bushing element that includes a sleeve with an axial length, a proximal end and a distal end. A load bearing flange is radially disposed about the proximal end of the sleeve. The sleeve has an internal thread extending at least part way of the axial length of the sleeve. A mounting screw element has a major axis, a head, and a shank disposed generally co-axially around the major axis. The shank includes a threaded shank portion and a bearing portion. The bearing portion is a generally cylindrical axially extending portion of the shank that has a diameter approximately equal to the minor diameter of the thread in the threaded shank portion. A thrust washer element is provided between the head and the distal end of the sleeve. A body element receives the in-turned opposed ends of the legs of a lifting loop element in sockets. The lifting loop is free to pivot.Type: GrantFiled: April 1, 2009Date of Patent: June 19, 2012Assignee: MJT Holdings LLCInventor: John Thomeczek

Publication number: 20120061982Abstract: A hoist ring assembly includes an anchor subassembly with bushing, retainer and threaded fastener elements, and a loop subassembly with a lifting loop and pair of pin elements. The assembly is adapted such that the lifting loop is rotatable through a 360-degree angle about a major axis, and pivotable through at least 180-degree angle about a minor axis. The assembly can be rapidly assembled or disassembled, and incorporates one or more components which may be substantially fabricated by way of forging operation, particularly the retainer member.Type: ApplicationFiled: September 15, 2011Publication date: March 15, 2012Applicant: MJT Holdings LLCInventors: Bernard J.

Patent number: 8113734Abstract: An eyebolt assembly is provided in which a skirt member is reinforced by radially projecting diametrically extending ribs. A fixed lifting eye projects from one side of the skirt, and a mounting stud projects from the opposite side. The mounting stud is double threaded with one thread being adapted to mate with a threaded bore in the body of the eyebolt assembly, and the other thread being matched to a threaded bore in a load. The same eyebolt body can be employed with a plurality of different mounting studs, which simplifies inventorying eyebolt assemblies to meet all of the different threaded bores that may occur in different loads. Only the mounting studs need to be threaded to match the loads. The skirts are provided with striking faces so that they can be tightened and loosened by striking them with a hammer.Type: GrantFiled: July 15, 2010Date of Patent: February 14, 2012Assignee: MJT Holdings, LLCInventors: Tony J.
