A cable retention and release mechanism includes a cable gripping device including a cable passage. A cable extends through the cable passage. A cable gripping device collar is movably coupled around the cable gripping device. An outer cable gripping device surface is seated against a cable gripping device receiving inner surface preventing movement of the cable gripping device relative to the cable gripping device collar. The cable gripping device receiving inner surface clamps the cable gripping device on the cable and prevents sliding movement of the cable. A jack is movably coupled with the cable gripping device collar. In a first engaged position the jack is engaged against the cable gripping device proximal end. In a second engaged position the jack unseats the outer cable gripping device surface from the cable gripping device receiving inner surface and releases the clamping of the cable.

Provided is an elevator rope terminal structure including an insertion body to be held in contact with an elevator rope having a flat sectional shape. Pressing portions provided to the insertion body are configured to maintain a state in which the insertion body is pressed against the elevator rope. The elevator rope and the insertion body are to be held inside a through hole of a housing. The through hole has an inner surface including a first receiving surface and a second receiving surface which are to be positioned on both sides of the elevator rope in a thickness direction of the elevator rope. A distance between the first receiving surface and the second receiving surface decreases toward a rope passage port of the through hole. The insertion body includes a first insertion member to be arranged between the elevator rope and the first receiving surface.

A swivel connector has a female part and a male part that are connected to each other so as to swivel. The female part has a main body with an interior cavity and an open face, and a strap connector. The male part has a plug portion and a strap connector. A ring lock locks the male portion to the female portion and is formed by two side walls connected by two pivot bars, the side walls of the ring lock being rotatably connected to the female part. The male part is locked to the female part by inserting the plug portion into the interior cavity, and rotating the ring lock into a locked position where the open face is blocked by one of the pivot bars. The male part is released from the female part by rotating the ring lock until the open face is not blocked by the pivot bar.

A net assembly comprising a) a first elongated member, b) a second elongated flexible member, c) a third elongated flexible member, d) a first connector, and e) a second connector, f) said first connector connecting the first elongated member and second elongated flexible member, g) said second connector connecting the second and third elongated flexible members, h) said first connector having a first end and a second end, said first end being connected to the first elongated member and said second end being connected to the second elongated flexible member, i) said second connector having a first end and a second end, said first end being connected to the second elongated flexible member and the second end being connected to the third elongated flexible member, and j) said first and/or said second end of said first and second connectors comprising a longitudinal displacement preventing element.

A hoisting device includes a body, a hoisting rope, a rope drum arranged in connection with the body, on which a first end of the hoisting rope is fastened, and a hoisting part which ascends and descends by means of the hoisting rope. The hoisting device includes a fastening device of a second end of the hoisting rope, which is formed into a loop wherein a spiral groove is substantially surrounding the entire loop and in which the part adjacent to the second end of the hoisting rope is received. The hoisting device further has a fastening arrangement which locks the second end of the hoisting rope to the fastening device, preventing the second end from being pulled out of the fastening device.
