  • the balance mechanism 23 for the counterweight 31 may be somewhat different from the balance mechanism 23 for the car 10 in size, etc., but because it is similar in function, it has been allocated an identical numeral in the figures for simplicity.
  • the balance mechanism 23 for the counterweight 31 is mounted to an upper portion of the counterweight 31.

The rest of the construction is similar to that of Embodiment 1.
  • a single counterweight 31 can be used and thus a single set of counterweight guide rails 32 is sufficient, enabling simplification of the overall construction. Furthermore, because the counterweight 31 is suspended by means of a balance mechanism 23, tilting can be prevented from arising in the counterweight 31 due to differences between the first and second driving machines 3 and 4, enabling the counterweight 31 to be raised and lowered smoothly.

  • the drive control portion 45 controls activation of the first and second driving machines 3 and 4 separately.
  • the angle of inclination detecting portion 46 detects the angle of inclination of the balance main body 25 by a signal from the pivoting sensor 41.

  • the inclination correcting portion 48 calculates a signal to cancel out the inclination of the balance main body 25 and outputs it to the drive control portion 45.
  • FIG. 9 is a flowchart showing the operation of the control apparatus 44 in Figure 8 .
  • the inclination determining portion 47 determines whether or not the angle of inclination of the balance main body 25 is less than or equal to the set value (Step S1). If the angle of inclination is less than or equal to the set value (i.e., horizontal or generally horizontal), a movement permission command is output from the inclination determining portion 47 to the drive control portion 45 (Step S2), and the first and second driving machines 3 and 4 are activated.

  • the inclination correcting portion 48 determines whether or not the angle of inclination is less than or equal to the set value, and if it is less than or equal to the set value, a movement permission command is output (Step S2).
  • Step S5 If the angle of inclination still exceeds the set value despite inclination removal control having been carried out, it is deemed that there is some abnormality in the control system or the drive system, activation of the first and second driving machines 3 and 4 is terminated, and an abnormality detection signal is output to an elevator control room, etc. (Step S5).
  • the inclination determining portion 47 calculates the speed of change in the angle of inclination of the balance main body 25 and determines whether or not the speed of change is less than or equal to a set value (Step S6). If the speed of change in the angle of inclination has exceeded the set value, that is, if the balance main body 25 has inclined suddenly, it is deemed that removal of the inclination is difficult, and the car 10 is decelerated and stopped or is stopped at a nearby floor (Step S7). Then, an abnormality detection signal is output to the elevator control room, etc.
  • Step S8 a determination is made as to whether or not the magnitude of the angle of inclination is less than or equal to the set value.
  • the set value constituting the criterion at this time may be the same as the set value when the car 10 is at rest or it may be different.
  • Step S9 determination of the speed of change and magnitude of the angle of inclination being performed continuously or periodically while the car 10 is moving.

  • the balance main body 25 can be maintained in a neutral state (i.e., horizontal) at the commencement of hoisting, enabling the operating performance of the car 10 to be further improved.
  • the balance main body 25 can also be maintained in a neutral state while the car 10 is moving, enabling the operating performance of the car 10 to be further improved.
  • Figure 10 is a front elevation showing part of an elevator apparatus according to Embodiment 5 of the present invention.
  • two pivoting sensors 49a and 49b for detecting pivoting of a balance main body 25 by detecting distances between a car 10 and a balance main body 25 are disposed between the car 10 and the balance main body 25.
  • the pivoting sensors 49a and 49b are disposed equidistantly from a pivoting shaft 24.
  • the rest of the construction is similar to that of Embodiment 4.
  • the angle of inclination of the balance main body 25 can also be easily monitored for the presence of abnormalities using pivoting sensors 49a and 49b of a type that detects the distance between the car 10 and the balance main body 25, enabling reliability to be improved.
  • determination of the angle of inclination of the balance main body 25 is made immediately before the car 10 starts moving, but a determination may also be made immediately after arrival at a floor, and determinations may also be made continuously while at rest.
  • a determination of the speed of change in the angle of inclination of the balance main body 25 is made from information from the pivoting sensor 41, but the car 10 may also be decelerated and stopped or stopped at a nearby floor if a preset limiting value for the pivoting angle is reached.
  • a limit switch activated when the balance main body 25 has inclined to a limiting value may also be disposed separately from the pivoting sensor.
  • Embodiment 5 a determination is made from the angle of inclination of the balance main body 25 found from distances between the car 10 and the balance main body 25, but a determination may also be made directly from the distances without finding the angle of inclination.
  • first and second driving machines 3 and 4 are installed in a machine room 2, but the present invention can also be applied to machine-roomless elevators in which the first and second driving machines are disposed inside a hoistway.
  • the first and second driving machines may be supported by a supporting beam secured to an upper portion inside the hoistway, or a supporting beam secured to upper portions of guide rails.
