A security device includes a flexible rope of diameter in the range 10-25 mm comprising helically wound strands with collars clamping the rope at spaced locations therealong. The spacing between the collars is less than or substantially equal to the rope diameter, and each collar has a wall thickness in the range 5-15% of the rope diameter. The axial length of each collar is normally no greater than the rope diameter. The collars engage the rope with sufficient pressure to prevent substantial relative lateral movement of the strands at each location.

A wire rope includes a strand that is formed by winding a plurality of metal wires. The strand includes a core wire and side wires. Each of the side wires is arranged on an outer periphery of the core wire. In a transverse section of the strand, each of the side wires includes end portions positioned at opposite ends in a circumferential direction of the core wire. Each of the end portions includes a contact portion in contact with an end portion of an adjacent side wire, and a non-contact portion not in contact with the adjacent side wire. A Vickers hardness of the contact portion is higher by 1% or more than a Vickers hardness of the non-contact portion. A surface roughness Ra of an outer peripheral surface of each of the side wires is 0.10 m or less.

Hybrid compensation member

A compensation and tie-down member for an elevator system includes one or more lightweight compensation tension elements having a first tensile strength/unit mass/unit length, and one or more heavier weight compensation tension elements having a second tensile strength/unit mass/unit length less than the first tensile strength/unit mass/unit length.
