A coupler for securing an attachment to an earth working machine. The coupler comprises a coupler body that presents a receptacle having a capture region. A pin of an attachment can move into and out of the capture region. A retainer can capture the pin in the capture region but the retainer can be moved by a hydraulically driven driver to a position to allow release the pin from the capture region. A trigger that the pin will strike when the pin moves into or out of the capture region, decouples the driver from the retainer and the retainer is then allowed to be biased back to its retaining position by a spring.

A non-frangible load release assembly having a pre-set tension for release is presented. The load release assembly comprises a snap shackle having a quick release and a link, a spring having a spring rate, and an actuating line with a length selected based on the spring rate to provide the pre-set tension for the load release assembly. The spring is attached to the link of the snap shackle. The actuating line is connected to the quick release of the snap shackle.

A device for releasably retaining a carabiner, said device includes: an elongate body with a jaw member hingedly attached at a first position thereto, said jaw member being movable towards and away from the elongate body in a first plane; a first projecting member and a second projecting member extending outwardly from a first side of the elongate body and away from the first plane; a third projecting member extending outwardly from a first side of the jaw member and away from the first plane, wherein the first projecting member and the second projecting member are configured to receive a spine of a carabiner inserted therebetween and whereupon third projecting member is configured to urge a gate of the carabiner toward the spine of the carabiner.

Embodiments disclosed herein relate to carabiners, carabiner retrieval devices and systems, and methods of retrieving a carabiner. In an embodiment, a carabiner retrieval device includes a neck, a retention device, and a retrieval cord retention structure. The neck has a length and includes a first end spaced from a second end along the length. The retention device extends from the first end of the neck at an obtuse angle relative to the length of the neck, and is configured to be attached to a gate of a carabiner. The retrieval cord retention structure extends from the second end of the neck, and is configured to retain a retrieval cord. When the retrieval cord is coupled to the retrieval cord retention structure and the retrieval cord retention device is attached to the gate of the carabiner, the gate opens responsive to the retrieval cord being pulled in a predetermined direction.

The invention relates to a coupler for coupling a substantially elongated belt portion, comprising a housing, comprising a first beam, extending substantially perpendicular to the longitudinal direction of the belt portions, for guiding a belt portion, a connector, located on a distance from the first beam, at least two sidewalls, which extend between the first beam and the connector, which sidewalls are located on opposite ends of the first beam, wherein at least a part of at least one side wall is pivotable between at least two positions: a closed position wherein the pivotable sidewall portion engages the first beam to limit a belt passage between the side walls, the connector and the first beam, and an opened position wherein the pivotable sidewall portion is located on a distance of the first beam to allow passage of a belt potion between the pivotable sidewall portion and the first beam.

A sling gear (1) for single-arm operation by a remotely controlled gripper may have a closure (4) that can be moved from a closed position (5) into an open position (82), a sling body (2) that is closed in the closed position (5) of the closure (4) and open in the open position (82), and an push-button (18) for opening the closure (4). The push-button (18) may have a gear section (68), which couples the closure (4) with the push-button (18), by transmitting movement. In order to improve the reliability in operation, also under adverse circumstances, for example in a heavily soiled environment on the seabed, the push-button (18) may be equipped with an locking area (56), which, in the closed position (5), is to be found engaged with the closure (4), and locks the closure (4) in the closed position (5).

A non-frangible load release assembly having a pre-set tension for release is presented. The load release assembly comprises a snap shackle having a quick release and a link, a spring having a spring rate, and an actuating line with a length selected based on the spring rate to provide the pre-set tension for the load release assembly. The spring is attached to the link of the snap shackle. The actuating line is connected to the quick release of the snap shackle.

A connector includes a first ring with a blocker collaborating with a rod. The rod is movable between a first position where the first ring is closed and a second position where the first ring is open. The blocker is movable between a first position collaborating with the rod to keep the first ring closed and a second position allowing opening of the first ring. A second ring includes a probe. The probe is connected to the blocker. When the distance between the probe and the sliding area is greater than a threshold value, the probe prevents opening of the first ring by the blocker. When the distance between the probe and the sliding area is smaller than the threshold value, the probe allows opening of the first ring by the blocker.

A connection device comprises a connector forming a ring with an open position and a closed position. A handle is fixed to the connector and has two extensions receiving a user's hands. The handle defines a tube extending in a first direction and a through hole arranged to pass through the tube perpendicularly to the first direction. A first end of a wire member forms a loop fixed to the connector in the tube. The second end of the wire member is fixed to the user. The connector passes through the through hole and the loop to fix the handle and the wire member to the connector.
