A rope control device a main body defining a central opening and first and second side portions, projections extending from the main body, an end recess defined by the first and second projections, an end friction surface formed at a juncture of a projection and the main body, and a bar. With the bar in a first position, the first rope portion is extended through the central opening and at least partly around the bar. With the bar in a second position, the main body and the bar define first and second opening portions of the central opening and the first rope portion is extended through the first and second opening portions and at least partly around the bar. The second rope portion is arranged within the first end recess such that, when the rope is under tension, the second rope portion frictionally engages the first end friction surface.

The present invention extends to a carabiner intended for use as an adjustable anchor or a belay device. In general, implementations include a carabiner that includes a frame defining a hole and a gate. More specifically, implementations include a carabiner having a spine with an elongated slot portion having a first slot wall and a second slot wall that define a hole through the spine of the frame. Additionally, some implementations include a carabiner kit with a first carabiner having an elongated slot portion on the spine, a second carabiner, a pinching mechanism formed by linking the first and second carabiners together, and a rope that goes through the elongated slot portion, around the second carabiner, and back out the elongated slot portion of the first carabiner to enable the pinching mechanism to selectively pinch the rope for use as an adjustable anchor or a belay device.

A retrieval tower for rescuing a person from within a grain bin or other storage structure having a sloped roof is disclosed. The tower comprises a base surrounding an opening in the roof. The base includes a clamp member insertable into the opening under a portion of the base so as to clamp a portion of the roof between the clamp member and base. A pair of spaced legs is attached to the base, and a head is supported by the upper ends of the pair of legs. At least one other leg extends down from the head and is attached to the base. The tower is movable from a first position in which a rescue rope will extend down from the head into the opening to a second position in which the rope is clear of the edge of the roof.

An emergency descender device preferably includes a base plate, a cover plate, a feed handle, a lock lever, a rope pulley, a release link and at least one spacer. The rope pulley is pivotally retained between the cover and base plates. The feed handle is preferably pivotally retained on the base plate. The lock lever pivots relative to the feed handle. A lock pin is pressed into the lock lever. A portion of the lock pin engages a perimeter of the cover plate to place the emergency descender device in either a lock position or a release position. The rope pulley grips an anchor rope against the at least one spacer in a locked position. One end of the release link is pivotally engaged with the rope pulley and an opposing end of the release link is pivotally engaged with the feed handle.

A rescue system for evacuating an incapacitated person from an elevated area includes a frame configured to be mounted on a pair of vertical posts extending upwardly from a surface of the elevated area, the posts defining a plane, wherein at least a portion of the frame is cantilevered out from the plane of the posts, and a lowering system supported by the cantilevered portion of the frame, the lowering system being configured to allow a rescuer to lower the incapacitated person by rope from the elevated area.
