An attachment that is configured for attachment to an arm of a piece of construction equipment. The attachment includes a pair of grapple mechanisms mounted on a main beam. Each grapple mechanism includes opposing grab arms mounted to a grab arm housing. The grab arm housings of the grapple mechanisms are each individually adjustable separate from one another relative to the main beam in one or more directions generally perpendicular to the longitudinal axis of the main beam. The attachment can fine adjust the positions of the pipe ends relative to one another until the ends align with each other, at which point the pipe ends can be welded or otherwise secured to each other while being held in position by the grapple mechanisms.

A boom mountable breaker system and a method of using same for interrupting electrical transmission through a portion of an energized conductor downstream of a desired break location. The method includes: mounting the jumper onto the energized conductor across the desired break location so as to form an electrically conductive first parallel electrical path; installing an in-line opener in the energized conductor at the desired break location on the energized conductor; positioning the breaker at the desired break location on the energized conductor, and electrically connecting the breaker, while open, across the desired break location and across the opposite ends of the jumper so as to form a second parallel electrical path when the breaker is closed; closing the breaker to thereby complete the second parallel electrical path; removing the jumper from across the desired break location; and, opening and then removing the breaker.

The purpose of the present invention is to provide a safe device with which, by forcibly braking the rotation of a grapple by means of an external force, it is possible even for an unskilled operator to bring the rotation to a halt and further to prevent accidents due to such rotation. Another purpose of the present invention is to provide such a device at lower cost. According to the present invention, a grapple has a lower frame that has claws for gripping timber and an upper frame that rotatably holds the lower frame, and is provided with a rotation braking means that applies a brake on the rotation of the lower frame.

A device is proposed for attaching a coupling device to a free-floating object, for example free-floating articles or free-floating persons. The device has: at least one first connection end, which can be connected to a load-receiving end of a lifting device; a coupling device for attachment to a free-floating object; a load-receiving connection between the first connection end and the coupling device; and a guiding device, which is separate from the load-receiving connection, connects the first connection end to the coupling device and is designed to guide the coupling device relative to the first connection end.

A subsea connector system (10) for providing a connection with a subsea well component comprises a latch assembly (14) defining a through bore and a latch member (18) mounted on the latch assembly. A mandrel (20) extends through said bore of the latch assembly, wherein the mandrel and the latch assembly are axially and rotatably moveable relative to each other in a predefined relative movement sequence to operate the latch member and configure the connector system between connected and disconnected configurations. The connector system also comprises a conveyance connector (22) for providing a connection between a conveyance member (24) and the mandrel such that a conveyance member may permit an axial movement component of the predefined movement sequence. A rotation interface (26) is mounted on one of the mandrel and the latch assembly such that a subsea manipulator may permit a rotational movement component of the predefined relative movement sequence.

A lifting device for a motor vehicle subassembly has a load-bearing unit with at least one support arm that can be pivoted around a longitudinal axis of the load-bearing unit and a coupling unit that is arranged on the support arm for releasably connecting the support arm to the motor vehicle subassembly. The coupling unit is mounted on the support arm such that it is longitudinally displaceable, and the load-bearing unit is configured to connect with a crane unit, such as a crane hook adapter. The lifting device is especially compact in construction in that it offers the possibility of being combined with lifting units for the disassembly of motor vehicle subassemblies from the ground. The load-bearing unit is releasably connected with a connecting body of a support unit. The connecting body is tiltable on the support unit.

Aspects of the present disclosure related to lifting apparatuses and methods for attaching and lifting a load, including for example a lifting apparatus that includes an outer sleeve with first and second openings, an inner unit that has a chamber, a first shear pin, a second shear pin, and an actuation device along with a bar that is positioned within and movable within a track. The bar may also include a projection sized and shaped to engage with a guide in a surface of the outer sleeve. In an unlocked position the first and second shear pins may be disengaged from the first and second openings in the outer sleeve such that the outer sleeve may move relative to the inner unit.
