A tip resistant system for use with a belay tether includes a user tether having a first length and configured to be connectable between a user and the belay tether. The user tether has a belay tether connector adjacent one end of the user tether, and a user connector adjacent an opposite end of the user tether. An auxiliary tether having a second length less than the first length of the user tether and configured to be connectable between the user and the user tether includes a user tether connector located adjacent a first end of the auxiliary tether, and an auxiliary user connector located adjacent a second end of the auxiliary tether opposite the user tether connector. The tip resistant system operates to maintain a user in a desired static attitude. A quick disconnect for use with a belay tether is also provided.

A line dispensing device includes a housing, a rotatable shaft rotatably supported by the housing and defining a rotational axis, and a line drum disposed about the rotational axis and configured to extend and retract a line from the housing. The line dispensing device also includes a retraction assembly disposed about the rotational axis and configured to generate a retraction force and retract the line from the housing, and a braking assembly disposed about the rotational axis and configured to generate a braking force on the line and during extension of the line from the housing.

A rope protector for protecting a rope as it passes through a grating. The rope protector comprises an enclosed channel portion, a head portion and a foot portion. The channel portion is waisted to allow the rope to be rotated within a hole in a grating. The head portion extends laterally from one end of the channel portion to prevent passage of the rope protector through the grating hole and the foot portion extends laterally from the other end of the channel portion to be passed through the grating hole when aligned with the grating hole and to prevent the foot portion being removed from the grating hole when rotated.

Disclosed is a smart emergency escape backpack, comprising a harness bound to a user and a controlled descent mechanism; wherein the controlled descent mechanism includes an anchor support, a hub mounted on the anchor support, and a centrifugal speed reduction damper fitted with the hub, a cable being wound around the hub; wherein a cable take-up actuating mechanism is further provided on the anchor support, and the cable take-up actuating mechanism includes an electric motor, a transmission structure connected to the electric motor, and a synchronous wheel connected to the transmission mechanism, the synchronous wheel actuating the hub to rotate reversely.

A self-retracting lanyard including a main body and a retractable line. The retractable line is coupled to the main body so as to be extendible and retractable relative to the main body and to be restricted from extending relative to the main body in response to a user of the self-retracting lanyard falling. The self-retracting lanyard further includes a manual control operable by the user to initiate controlled descent of the retractable line relative to the main body.
