Abstract: A torque limiting tool is described. The tool comprises a torque limiting mechanism comprising a sleeve connectable to a drive shaft and a torque drive coupler that resides within a housing. The sleeve comprises a sleeve annular sidewall having a plurality of outwardly projecting elongated first lobes and recessed first grooves that are circumferentially positioned along the length thereof. The drive coupler comprises a socket defined by a coupler annular sidewall having a plurality of outwardly projecting second elongated lobes and recessed second grooves positioned along the coupler interior sidewall. Torque is transferred therebetween when the ramped surfaces of the first and second lobes mate within respective second and first grooves of the coupler and sleeve. When a torque limit is exceeded, the first and second lobes of the sleeve and coupler disengage for their respective second and first grooves.

Abstract: The present invention provides a wrench, and its structure includes a guide rod, a first pawl mounted on the guide rod, a sliding member sheathed on the guide rod, a second pawl mounted on the sliding member and matching with the first pawl, and a toothed block disposed on the sliding member and matching with the guide rod. The toothed block has a first position and a second position. When the toothed block is in the first position, the toothed block is slidable along the guide rod toward the first pawl, and is locked in the direction away from the first pawl. When the toothed block is in the second position, the toothed block is slidable along the guide rod toward or away from the first pawl.

Abstract: A fastener installation tool and related method are provided for installing fasteners in boards. The tool can include a feed mechanism that automatically and sequentially feeds collated fasteners to a nose assembly. The nose assembly can include a guide having an alignment projection extending downwardly from the guide, and configured to engage a board corner and/or side surface, so as to align an angled bore through which fasteners are guided with the board corner and or side surface. The nose assembly can include a magnetic element located adjacent a path on which the collated fasteners are advanced. The magnetic element can exert a magnetic force on an individual fastener, aligning it for precise entry into the angled bore. The nose assembly can include a guide pocket to positively constrain a fastener as it rotates to ensure a desired advancement trajectory. A related method of installation is provided.

Each of the actuators provides a cylinder, and a piston sliding in the cylinder and forming with the cylinder an annular chamber dedicated to be supplied with pressurized fluid. According to the invention, the at least second actuator is temporary axially arranged between the first actuator and the tubular support sleeve for a temporary blockwise assembly, the pistons of two axially adjacent actuators being indexed in rotation together.

Abstract: A tensioning device for a thread end portion of a bolt has a cylindrical housing and a piston, moveable in longitudinal direction therein and connectable to a hydraulic supply. An interchangeable sleeve extends centrally through the piston. At its end it has an internal thread with engagement length to be screwed onto the thread end portion. The sleeve has a radially expanded portion carried axially by a carrier face of the piston. In order to prevent the sleeve from prematurely contacting the threaded bolt when mounting the bolt tensioning cylinder and prevent damage to the threads, the sleeve is moveable longitudinally relative to the piston. The longitudinal sleeve travel is defined by the carrier face as first longitudinal stop and by a second longitudinal stop. The longitudinal sleeve travel is at least equal to, preferably greater, than the engagement length of the internal thread of the sleeve.

Abstract: A power tong positioner has one or more eddy current probes mounted in association with a power tong/backup unit. An electric current runs through the probe, and with the probe positioned close to a tubular connection, movement of the probe along the length of the connection, with the electric field encompassing surface features on the tubular, will cause a change in the electrical impedance (conductivity) which enable identification of the connection seam or other defined attributes (the “target” attributes). The power tong/backup unit can be positioned accordingly. A portfolio of profiles of non-connection seam surface features of different tubular connections may be generated, stored in a database, and accessed by the system, which enables identifying the connection seam/face with greater accuracy. Other attributes of the invention include storing profile information on RFID tags, and storing and accessing tubular information from a cloud server or other form of remote database.

Abstract: A dual fastener manipulation device may be used to manipulate two fasteners, having the same rotational axis, which may be separated by various distances and various sized objects. The dual fastener manipulation device may include a first wrench having a first fastener engaging head, a first handle, and a pivot stud. A second wrench element may have a second fastener engaging head and a second handle. A pivot linkage may be pivotally coupled to the pivot stud, and a floating stud may be coupled to both the second wrench and to the pivot linkage. The first and second fastener engaging heads may be engaged to two fasteners having the same rotational axis, while the pivot linkage and floating stud may maintain the rotational axis of the fastener engaging heads, while also allowing the fastener engaging heads to be moved closer to or farther from each other.
