- the inner layer strands 3 are constructed by twisting a plurality of steel wires 6 together with each other.
- the cross-sectional structure of the inner layer strands 3 is warrington (Japanese Industrial Standards (JIS) G 3525).

- a surface of the rope grooves 45 contacting the elevator ropes 36 is constituted by a high-friction resin material (a resin lining) 46.
- an inner layer coating body 7 made of resin is disposed between the inner layer rope 1 and the outer layer 8, the inner layer strands 3 and the outer layer strands 9 are prevented from direct contacting and rubbing against each other, enabling deterioration due to abrasion to be prevented and bending stresses to be alleviated by a buffer action, thereby enabling extension of the service life of the elevator ropes 36.
- the high-friction resin material 46 it is preferable for the high-friction resin material 46 to have a coefficient of friction greater than or equal to 0.2, enabling sufficient transfer efficiency of the driving force to be ensured. Furthermore, provided that the coefficient of friction is greater than or equal to 0.2, the high-friction resin material 46 is not limited to polyurethane, and polyvinyl, etc., can also be used.
- Soft or hard polyurethane resin can also be selected freely, but in order to ensure abrasion resistance performance against phenomena such as the elevator ropes 36 slipping slightly on the surface of the sheaves 35, 38, 40, 41, and 42, it is preferable to use hard polyurethane resin having a hardness of 85 to 98. In particular, polyurethane resin having a hardness greater than or equal to 90 is most preferable. In order to prevent hydrolysis from occurring in the service environment, it is also desirable that the resin be ether-based rather than ester-based.
- the high-friction resin material 46 is disposed in the rope grooves 45, processing is facilitated compared to when an outermost circumference of the elevator ropes 36 is coated with a high-friction resin material.
- flexing resistance can be reduced by selecting as the material for the inner layer coating body 7 a material that slides freely and easily when the elevator ropes 36 are bent at the sheaves 35, 38, 40, 41, and 42. Furthermore, the inner layer coating body 7 requires a hardness that can resist being crushed between the wires 6 of the inner layer strands 3 and between the wires 11 of the outer layer strands 9.
- a hard, low-friction polyethylene material is suitable as this kind of the material.
- a resin such as nylon, silicon, polypropylene, or polyvinyl chloride, etc., for example, may also be used as the material for the inner layer coating body 7.
- the outer layer strands 9 have a simple seven-wire construction including a central wire 10 and six outer peripheral wires 11, the diameter of the elevator ropes 36 can be reduced and disarray can be suppressed.
- the cross-sectional construction of the inner layer strands 3 is warrington, not seale or filler wire, breakage of the wires 6 due to wear can be prevented without using extremely slender wires 6, enabling extension of service life.
- the wires 6 can be disposed in a well-balanced manner without strain, enabling wear of the wires 6 to be further prevented.
- the rotational torque in the interior portions can be balanced, enabling the overall twisting return torque of the rope to be reduced.
- elevator ropes 36 having high flexibility as described above are wound around sheaves 35, 38, 40, 41, and 42 having a small diameter, there is a risk that contact pressure between the sheaves 35, 38, 40, 41, and 42 and the outer layer strands 9 may increase, considerably advancing wear and tear on the sheaves 35, 38, 40, 41, and 42 and the outer layer strands 9.
- the car guide pulley 41 and the counterweight guide pulley 42 can be disposed in the space above the car 37 without increasing the height dimensions of the hoistway 31, and it is not necessary to widen the cross sectional area of the hoistway 31.
- the diameter of the car guide pulley 41 and the counterweight guide pulley 42 is greater than or equal to fifteen (15) times the diameter of the rope in elevator apparatuses not operating frequently, and greater than or equal to twenty (20) times in busy elevator apparatuses to enable sufficient service life to be ensured.
- the diameter of the guide pulleys 41 and 42 is set within a range of fifteen to twenty (15 to 20) times the diameter of the rope, the height dimensions of the hoistway 31 can be reduced effectively.
- the diameter of the guide pulleys 41 and 42 is set within a range of the installed height of the driving machine 33, the height dimensions of the hoistway 31 can be reduced even more effectively.
- FIG. 7 is a cross section of an elevator rope according to Embodiment 2 of the present invention.
- an inner layer rope 23 has: a core rope 24; and a plurality of inner layer strands 25 disposed on outer peripheral portions of the core rope 24.
- the core rope 24 has a plurality of core strands 26.
- Each of the core strands 26 is constructed by twisting a plurality of steel wires 27 together with each other.
- the inner layer strands 25 are constructed by twisting a plurality of steel wires 28 together with each other.
- the cross sections of the wires 28 in the inner layer strands 25 are modified by compressing the inner layer strands 25 from an outer periphery.
- the cross sections of the wires 27 in the core strands 26 are modified by compressing the core strands 26 from an outer periphery. The rest of the construction is similar to that of Embodiment 1.
- the shape of the cross sections of the wires 10 and 11 in the outer layer strands 9 can also be modified by compressing the outer layer strands 9 from an outer periphery.
- Figure 8 is a side elevation showing an elevator rope according to Embodiment 3 of the present invention cut away in layers.
- inner layer strands 3, core strands 4, and outer layer strands 9 are twisted the same direction as each other.
- the rest of the construction is similar to that of Embodiment 1.
- the ropes shown in Embodiments 1 to 3 which have multilayered constructions, have characteristics by which the load burden rate of each of the layers is changed by fatigue over time.
- the strength burden ratio in layers in which damage proceeds preferentially is reduced, although this varies depending on the construction of the ropes.
- it is preferable to detect abnormalities in a weakest layer by setting the strength of one layer to twenty to eighty percent (20% to 80%) and to change the ropes before the overall strength deteriorates significantly.
- the sum total strength of the strengths of the outer layer strands 9, which are in the weakest layer where bending stresses are at their greatest is preferable for the sum total strength of the strengths of the outer layer strands 9, which are in the weakest layer where bending stresses are at their greatest, to be set to within twenty percent (20%) of the overall strength of the elevator rope.
- a residual strength of nearly 80 percent (80%) can be ensured in the inner layer rope 1 alone, enabling reliability to be improved.
