A rope edge protector for protecting a rope as it passes over an edge during rope access and rope rescue is described. The rope edge protector has a body with a curved channel portion on an outer surface thereof that is configured to receive at least one rope along a length of the channel portion. The body has a first underside surface that is configured for placement on a first face of the edge and a second underside surface forming a dihedral angle with the first underside surface and that is configured for placement on a second face of the edge. An attachment mechanism having a strap may connect the body to a second body and may have a cam for tensioning the strap between the bodies to secure the bodies to opposing edges.

Methods and apparatus for an emergency descent system according to various aspects of the present technology may comprise a cable connector non-slidably connected to an emergency escape cable and a housing connected to the cable connector and configured to enclose a controlled descent system and at least a portion of a length of rope. The housing may comprise an outer protective layer, an inner wall section substantially enclosed by the outer protective layer forming an open interior portion, and a cover configured to be selectively attached to an upper portion of the outer protective layer. The cover may be configured to be selectively attached to an upper portion of the outer protective layer. The cover may be configured to cover at least a portion of the controlled descent system and protect the open interior portion from environmental conditions.

A safety restraint anchor system may include, but is not limited to: a pole portion; a circumferential frame portion disposed about an axis of the pole; and at least one safety line anchor.

The brake system composes a circular wheel, brake shoes, brake disc and cable reel rotation. The rubbing action between brake shoes and brake disc generating from the rotation of Axle rotating with the planetary gear, which is driven by the cable reel, reduces the falling speed. (Falling speed about 1.7 meters per second) The inner cable is designed with a length of 82 meters and max load of 177 kg. The decelerator of this device could stop the falling immediately by using hand brake, in order to achieve rescue and avoid probable injure.

A wind turbine tower evacuation tool is provided including an object end for attachment to an object or a person and a roller end configured for connection to a surface of a wind turbine tower by magnetic attraction. The roller end includes at least one magnet body arranged for rotation around a rotational axis of the roller end. The wind turbine tower evacuation tool further includes a rope element connecting the object end to the roller end.

An edge protector mat is formed from a mat with a top surface, a bottom surface, and a number of metal bars. The top surface contains a number of receptacles grouped into one or more pairs sized, shaped, and otherwise configured to receive opposing ends of the metal bars therein. Each of the metal bars define opposing ends, different ones of which are positioned within corresponding ones of the pair of the receptacles of the top surface. The metal bars are configured to prevent friction from being imparted onto the mat. At least one pair of the receptacles are positioned opposite one another on the mat allowing receipt of different portions of at least one of the metal bars.

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.
