  • a car 2, a first counterweight 3, and a second counterweight 4 are disposed inside a hoistway 1.
  • the car 2, the first counterweight 3, and the second counterweight 4 are raised and lowered inside the hoistway 1.

  • the drive sheave 8 is rotated directly by the motor without a reduction gear.
  • the driving machine 6 is disposed such that a rotating shaft of the drive sheave 8 is vertical (also including generally vertical).
  • the driving machine 6 is also disposed such that the drive sheave 8 is positioned below the driving machine main body 7.
  • the driving machine 6 is disposed so as to overlap generally centrally with the car 2 when viewed from above. In other words, the driving machine 6 is disposed generally centrally inside the machine room 5.
  • a main rope group 10 that suspends the car 2 and the counterweights 3 and 4 is wound around the drive sheave 8.
  • a plurality of first main ropes 11 (only one is shown in the figures) that suspend the car 2 and the first counterweight 3, and a plurality of second main ropes 12 (only one is shown in the figures) that suspend the car 2 and the second counterweight 4 are included in the main rope group 10.
  • the number of first main ropes 11 is equal to the number of second main ropes 12.
  • the total number of main ropes contained in the main rope group 10 is determined by constraints such as main rope safety factors prescribed by law, etc.
  • the number of first and second main ropes 11 and 12 is half the total number of main ropes, respectively.

  • small regions are present at two circumferential positions on the drive sheave 8 where neither the first nor second main ropes 11 and 12 are wound around. Consequently, wind-around angles of the first and second main ropes 11 and 12 on the drive sheave 8 are less than 180 degrees, respectively.
  • a deflection pulley group 14 that directs the main rope group 10 from the drive sheave 8 toward the car 2 and the counterweight 3 and 4 is disposed in the machine room 5.
  • a second car deflection pulley 17 that directs the second main ropes 12 from the drive sheave 8 toward the car 2

  • the second hanging position 13b is similar.
  • an approach angle of the main ropes 11 and 12 onto the drive sheave 8 is maximized in the main rope positioned furthest outside on the deflection pulleys 15 through 18.
  • the main rope group 10 is divided into first and second main ropes 11 and 12 in this example, the number of main ropes that are wound around each of the deflection pulleys 15 through 18 is halved (or approximately halved). Consequently, the approach angle onto the drive sheave 8 of the main rope positioned furthest outside on the deflection pulleys 15 through 18 can be reduced. In other words, the distance between the drive sheave 8 and the deflection pulleys 15 through 18 can be reduced.
  • the driving machine 6 can be disposed in the vicinity of the center of the machine room 5, and interference with wall portions of the machine room 5 is avoided even if the diameter of the motor of the driving machine 6 is increased, making it unnecessary to expand the space of the machine room 5. In other words, additional reductions in the thickness of the driving machine 6 can be achieved.
  • Figure 3 is a front elevation showing an elevator apparatus according to Embodiment 2 of the present invention and Figure 4 is a plan showing the elevator apparatus in Figure 3 .
  • a driving machine 6 and a deflection pulley group 14 are disposed in an upper portion inside a hoistway 1.

  • First and second main ropes 11 and 12 are connected to the first and second rope connecting portions 2e and 2f.
  • the rest of the configuration is similar to that of Embodiment 1.
  • the driving machine 6 can be disposed in the vicinity of the center of the upper portion inside the hoistway 1. Consequently, it is not necessary to expand the space of the hoistway 1 even if the diameter of the motor of the driving machine 6 is increased.
  • the driving machine 6 can also be reduced further in thickness. Thus, increases in vertical dimensions and horizontal dimensions of the hoistway 1 can be prevented.
  • the driving machine main body 7 is disposed under the drive sheave 8
  • maintenance inspection work on the driving machine main body 7 can be performed easily from on top of the car 2.
  • the rope connecting portions 2e and 2f are disposed on the car 2
  • the distance between the deflection pulleys 15 and 17 and the drive sheave 8 can be increased, enabling the approach angle of the main ropes 11 and 12 onto the drive sheave 8 to be reduced.
