  • the respective car suspending pulleys 9 and 10 are disposed symmetrically with respect to a center point of a line segment connecting the respective car guide rails 2 to each other on the vertical projection plane of the hoistway 1 ( Fig. 2 ).
  • a first car side return pulley 11 and a second car side return pulley 12 are provided in the upper portion within the hoistway 1 and above the car 4. Each of the first car side return pulley 11 and the second car side return pulley 12 is rotated around a horizontally extending rotational shaft.
  • the first car side return pulley 11 is disposed above one of the car suspending pulleys 9.
  • the second car side return pulley 12 is disposed above the other car suspending pulley 10.
  • the first counterweight rope connecting portion 13 and the second counterweight rope connecting portion 14 are disposed on the line connecting the respective counterweight guide rails 3 to each other on the vertical projection plane of the hoistway 1 ( Fig. 2 ). Further, the first counterweight rope connecting portion 13 and the second counterweight rope connecting portion 14 are disposed symmetrically with respect to a vertical line extending past a center of gravity of the counterweight 5.
  • a first counterweight side return pulley 15 and a second counterweight side return pulley 16 are provided in the upper portion within the hoistway 1 and above the counterweight 5.

The second counterweight side return pulley 16 is disposed above the second counterweight rope connecting portion 14.
  • the car 4 and the counterweight 5 are suspended within the hoistway 1 by a plurality of main ropes 17 (only one rope is illustrated in the drawings for the sake of simplicity).
  • Each of the main ropes 17 has a first rope end 17a connected to the first counterweight rope connecting portion 13, and a second rope end 17b connected to the second counterweight rope connecting portion 14.
  • Each of the main ropes 17, which extends from the first rope end 17a to the second rope end 17b, is sequentially wound around the first counterweight side return pulley 15, the driving sheave 8, the first car side return pulley 11, the one of the car suspending pulleys 9, the other car suspending pulley 10, the second car side return pulley 12, and the second counterweight side return pulley 16. That is, as for the respective main ropes 17, there is adopted a 1:1 roping method in which the moving distance of each of the main ropes 17 is equal to the moving distance of the car 4 and the counterweight 5.
  • Each of the main ropes 17 is manufactured by twisting a plurality of copper wires. Each of these wires has a wire diameter smaller than a normal wire diameter. Thus, the respective main ropes 17 are increased in flexibility.
  • the respective main ropes 17 may also be designed as synthetic fiber ropes to achieve further enhancement of flexibility.
  • a first rope tension T1 is applied to portions of the main ropes 17 which are located on the first rope end 17a side with respect to the driving sheave 8

  • the total weight W2 on the car 4 side is balanced with the weight W1 of the counterweight 5 when the laden weight Wb is half of a maximum laden weight Wbmax.
  • the magnitudes of the first rope tension T1 and the second rope tension T2 may be different from each other. Accordingly, the larger the clearance between the first counterweight rope connecting portion 13 and the second counterweight rope connecting portion 14 becomes, the larger the offset load applied to the counterweight 5 becomes, and the larger the reactive force applied to each of the counterweight guide rails 3 becomes.
  • the level of a noise resulting from contact of the counterweight 5 with the respective counterweight guide rails 3 may be increased, or the life of the counterweight guide rails 3 may be shortened due to abrasion.
  • the clearance between the first counterweight rope connecting portion 13 and the second counterweight rope connecting portion 14 is set within a predetermined range where an adverse effect resulting from an offset load applied to the counterweight 5, for example, a noise, abrasion of the counterweight guide rails 3, or the like can be permitted.
  • the first counterweight rope connecting portion 13 and the second counterweight rope connecting portion 14 are disposed on the counterweight 5 in close proximity to the vertical line extending past the center of gravity of the counterweight 5.
  • the drive device 6 is horizontally provided in the upper portion within the hoistway 1, and each of the main ropes 17 for suspending the car 4 and the counterweight 5 within the hoistway 1, which extends from the first rope end 17a connected to the counterweight 5 to the second rope end 17b connected to the counterweight 5, is sequentially wound around the first counterweight side return pulley 15, the driving sheave 8 of the drive device 6, the first car side return pulley 11, the one of the car suspending pulleys 9, the other car suspending pulley 10, the second car side return pulley 12, and the second counterweight side return pulley 16.
  • the axial load applied to the driving sheave 8 can be made equal to the weight of the counterweight 5, and the moving distance of the main ropes 17 can be made directly equal to the moving distance of the car 4 and the counterweight 5. That is, both the total weight W2 on the car 4 side and the weight W1 of the counterweight 5 can be prevented from being directly applied to the driving sheave 8, and the 1:1 roping method is adopted as to the main ropes 17, so the rotational speed of the driving sheave 8 can be reduced. Accordingly, the drive device 6 can be reduced in size, and the space of the hoistway 1 can be reduced. Further, a noise resulting from rotation of the driving sheave 8 can also be abated.
  • the respective car suspending pulleys 11 and 12 are disposed symmetrically with respect to the center point of the line segment connecting the respective car guide rails 2 to each other on the vertical projection plane of the hoistway 1. Therefore, the car 4 can be stably suspended by the main ropes 17.
  • the first counterweight rope connecting portion 13 and the second counterweight rope connecting portion 14 are disposed symmetrically with respect to the vertical line extending past the center of gravity of the counterweight 5, and the clearance between the first counterweight rope connecting portion 13 and the second counterweight rope connecting portion 14 is set within the predetermined range. Therefore, the magnitude of an offset load applied to the counterweight 5 can be set within a permissible range. Thus, a noise resulting from, for example, contact of the counterweight 5 on the counterweight guide rails 3 can be abated, and the life of the counterweight guide rails 3 can be restrained from being shortened due to abrasion.
  • the drive device 6 is designed as a low-profile hoisting machine having a dimension in an axial direction which is smaller than a dimension in a radial direction, so the dimension of the hoistway 1 in a height direction thereof can further be reduced.
  • the car suspending pulleys 9 and 10 are provided on the lower portion of the car 4.
  • the car suspending pulleys 9 and 10 may also be provided on an upper portion of the car 4. In this manner as well, the car 4 can be suspended within the hoistway 1 by the main ropes 17.

  • the present invention may also be applied to an elevator apparatus of counterweight-falling-behind type in which the counterweight 5 is disposed behind the car 4.
