Rope-Lowering Device and Corresponding Lowering Method
The invention relates to a rope-lowering device for lowering persons from a building or the like, comprising: an axle arranged to rotate about its longitudinal axis; a first reel connected or connectable to the axle; a second reel connected or connectable to the axle; a brake connected to the axle, which brake is configured to provide a braking force to the axle independent of a direction of rotation; a first rope connected to the first reel to be suspended from the first reel; and a second rope connected to the second reel to be suspended from the second reel, wherein the rope-lowering device is configured such that when both the first and second reels are connected to the axle, paying out one of the first and second rope will automatically cause the other one of the first and second rope to be hauled in.

Controlled descent self-retracting lanyard
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.

FALL ARRESTER
A fall arrester includes a holder, rotating drum, braking device, and dust cover. The rotating drum is pivotally provided on and within the holder, and includes a main body and at least one pawl; the main body has an accommodating part to be wound by a cable and a setting part. The pawl is pivotally provided on the setting part, and the braking device is fixed to the holder and between the holder and the setting part. When the rotating drum rotates quickly by pull of the cable, the pawl would pivot and make a part thereof abut against a part of the braking device to stop the rotating drum. The dust cover is fixed to the setting part, and thereby prevents dust from affecting the pawl and the braking device located therein, and thus to enhance safe use thereof.

Safety apparatus comprising mechanical command interface
A fall-protection apparatus that includes a computing device configured to detect a mechanical command signal, and methods of using such an apparatus.
WIND TURBINE TOWER EVACUATION METHOD AND TOOL
A wind turbine tower evacuation tool (10) is provided comprising an object end (20) for attachment to an object (500) or a person (555) and a roller end (30, 301, 302, 303) configured for connection to a surface of a wind turbine tower (110) by magnetic attraction. The roller end (30, 301, 302, 303) comprises at least one magnet body (33) arranged for rotation around a rotational axis of the roller end (30, 301, 302, 303). The wind turbine tower evacuation tool (10) further comprises a rope element (11) connecting the object end (20) to the roller end (30, 301, 302, 303).

Rope protector and associated methods
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.
