This is because, as described above for the problems to be solved by the invention, the traveling cable 10 rolls back and forth and around due to wind pressure as the car 11 travels. Especially, a traveling cable used in an elevator with a large stroke becomes long and tends to roll easily. To cope with this rolling, the sway prevention mechanism 130 is provided to reduce a bending force (moment) applied to the thimble rods 30L, 30R.
  • Fig. 6 illustrates suspension by one of the two suspending wire ropes embedded in the traveling cable 10, i.e., the wire rope 10L, in the suspending apparatus at the midpoint of the hoistway illustrated in Figs. 2A and 2B .

  • the thimble rod 30L is fixed and supported by the bracket 110.
  • the bending moment M that the thimble rod 30L receives when the traveling cable 10 rolls is considered.
  • the thimble rods will receive such large bending moment as well as repeated moment of 0 to about 900 N.m. In order to resist this moment, robust thimble rods of large diameters are required. Such robust thimble rods of large diameters need larger rope sockets for attachment.
  • the sway prevention mechanism 130 of traveling cable is to prevent this bending moment, and can eliminate the necessity of thicker thimble rods and larger rope sockets to attach the thimble rods and can achieve a configuration using thimble rods of small diameters taking account of the strength for vertical tensile load only and rope sockets corresponding to such diameters. Therefore, a small and reliable suspending apparatus can be achieved.

  • Fig. 5 illustrates the details at the traveling cable suspending apparatus on the car side.
  • the sway prevention mechanism 130 of traveling cable on the hoistway side of Fig. 4 is attached in the following manner. After a plate steel 131 is provided on two L-section steels 121a, 121b fixed and supported at the building and provided vertically, the traveling cable 10 is attached to the plate steel 131 so as to be covered with a hat-shaped fitting 132 as illustrated in the drawing.

  • Such dimensions of the internal dimensions of the hat-shaped fitting equal to or slightly larger than the outside diameter size of the traveling cable prevents the weight of the traveling cable from applying to the sway prevention mechanism, and so the sway prevention mechanism can be configured with a simple plate steel and such a hat-shaped fitting to suppress rolling only.
