The invention relates to a rope sling shackle body for a heavy load rope sling shackle for suspending on a rope sling, at least comprising: two mutually opposite end portions each with a through-opening for receiving a pin; a central arc which extends between the end portions and which has, at least in a rope receiving region, an arc bottom and arc flanks that are arranged on either side thereof and are spaced apart from one another, wherein the arc has a convexly rounded rope supporting face on its inner side at least in the rope receiving region, said rope supporting face extending from a top edge of one arc flank to the top edge of the respectively other arc flank; and at least one reinforcement rib, which is arranged between the arc flanks. The reinforcement rib is divided into two part-ribs via which in each case one arc flank is supported on the arc bottom, wherein there is a spacing between the part-ribs right down to the arc bottom.

Fall protection apparatus includes a self-retracting lifeline, a tether line and a link member enabling connection of the self-retracting lifeline to the tether line. An anti-connection device is fitted to the link member permitting connection to the self-retracting lifeline but inhibiting connection to other devices when connected to the self-retracting lifeline.

A shackle comprises a shackle body and a shackle jaw, the shackle jaw connected to the shackle body by a pivot element about which the shackle jaw and shackle body may pivot relative to one another. The shackle further comprises an actuator element and an actuator and a locking element, the locking element arranged to engage the shackle body and the shackle jaw in a locking configuration and to disengage from the shackle jaw in a release configuration. The locking element is slidable along its longitudinal axis between the locking and release configurations and the actuator element is arranged to slide along its longitudinal axes. The pivot element, the actuator element and the locking element are connected to one another by a lever that is pivotally attached at one end to the shackle body and wherein the connection between the lever and the locking element and the actuator element permits pivotal movement and limited linear movement between the lever and the locking and actuator elements.

A pressure-release clamping assembly for an anchor assembly that includes clamping body defining a lower opening, having a pin coupled thereto and configured to restrict ambient access to the lower opening, defining an upper opening, having a clamping member translatably coupled to the clamping body, and having a pressure-release latch configured to lockedly couple with the clamping member and with a latch spring operably configured to bias the pressure-release latch toward the clamping member. The clamping member is operably configured to rotate and have a locked and an upper opening enclosing position with the clamping member retained in the locked position with the pressure-release latch, wherein the clamping member is configured to disengage with the pressure-release latch upon receiving at least a 100 lbf oriented with a longitudinal axis of the pressure-release latch and a released position with the clamping member at least partially removed from the clamping body.

A pinned connection assembly includes a first rigging component, a second rigging component, a rigging pin, a locking pin, and a lock. The first rigging component has an end with at least one coupling aperture and at least one retention aperture that is transverse to the coupling aperture. The second rigging component has an end with at least one coupling aperture. The rigging pin has an end with a retention groove. The rigging pin is inserted through the coupling apertures of the first and second rigging components. The locking pin has an end with a locking groove. The locking pin is inserted through the retention aperture and the retention groove. The locking groove has guide, transitional, and locking portions for engaging a key of the lock.

A throwing hook including with particular, but not exclusive, use in arborism is disclosed. The hook includes a body that extends in a plane to form a bight profile and a shackle. The shackle includes a loop through which a line can be secured. The shackle is secured to the body such that the shackle and the body can pivot freely with respect to one another about an axis that lies within the plane. Embodiments may further include release elements operable by a user to facilitate release of the hook from an anchorage.
