Embodiment approach 1

[0020] figure 1 To show a side view of the elevator rope according to Embodiment 1 of the present invention, figure 2 for figure 1 Cutaway view of an elevator with ropes. In the figure, a steel core rope 1 is arranged at the center of the elevator rope. A core rope covering body 2 made of resin is provided on the outer periphery of the core rope 1 . A plurality of (here, eight) steel core rope sub-ropes 3 are twisted on the outer periphery of the core-rope covering body 2 .

[0021] A core rope covering body 5 made of resin is provided on the outer periphery of the core rope covering body 2 and the core rope strand assembly 4 composed of eight core rope strands 3 . The core rope 6 is composed of a core rope 1 , a core rope covering body 2 , a core rope sub-rope 3 and a core rope covering body 5 .

[0022] A plurality of (here, 20) steel outer layer strands 7 are twisted around the outer periphery of the core rope covering body 5 . The rope body 8 is composed of a core r...

Embodiment approach 2

[0050] then, image 3 It is a side view showing the elevator rope according to Embodiment 2 of the present invention. In the drawing, on the surface of the outer layer covering body 9 , in addition to the inspection result information 31 and the position information 32 , the manufacturing information 33 is also recorded. As the manufacturing information 33 , a manufacturer's name, a lot number, a manufacturing date and time, and the like are listed.

[0051] In addition, the manufacturing information 33 is printed at the same pitch as the inspection result information 31 and the position information 32 in the rope length direction. In addition, the manufacturing information 33 is printed at a different position from the inspection result information 31 and the position information 32 in the circumferential direction of the outer layer covering body 9 . The other structures are the same as those in Embodiment 1.

[0052] In such an elevator rope, since the manufacturing info...

Abstract

In an elevator apparatus, a car is suspended by an elevator rope inside a hoistway. The elevator rope includes: a rope main body; and a resin outer layer coating body that is coated onto an outer circumference of the rope main body. Test result information that corresponds to a given position of a test that is carried out in a rope longitudinal direction during manufacturing is applied to a surface of the outer layer coating body at a predetermined pitch.

Description

technical field [0001] The present invention relates to an elevator rope whose outer periphery is covered with a resin outer layer covering body. Background technique [0002] In the conventional elevator ropes, abnormalities and damages can be visually confirmed from the appearance of the ropes in many cases, and therefore a certain degree of inspection can be carried out before actual use. On the other hand, in the elevator rope whose outer circumference is covered with a resin covering body, the thickness of the covering and the presence or absence of broken wires inside cannot be confirmed visually. [0003] In addition, in conventional engineering fiber ropes, a synthetic resin coating is provided on the outer periphery of the fiber rope main body, and manufacturing or sales dates are printed at predetermined intervals on the surface of the synthetic resin coating (for example, refer to Patent Document 1). [0004] prior art literature [0005] patent documents [0...
