  • a driving machine and a control panel, etc. are disposed using vacant space inside the hoistway.
  • the present invention aims to solve the above problems and an object of the present invention is to provide an elevator apparatus enabling a large equipment installation space to be secured inside a hoistway.
  • an elevator apparatus including: a driving machine having a drive sheave; a main rope wound onto the drivingmachine; and a car and a counterweight suspended inside a hoistway by the main rope so as to be raised and lowered inside the hoistway by a driving force from the driving machine, wherein: the car and the counterweight are suspended at mutually-differing roping ratios such that a hoisting zone of the counterweight is shorter than a hoisting zone of the car; and an equipment installation space is secured inside the hoistway by making use of the difference between the hoisting zone of the car and the hoisting zone of the counterweight.
  • Figure 1 is a schematic structural diagram showing an elevator apparatus according to Embodiment 1 of the present invention.
  • a pair of car guide rails (not shown) and a pair of counterweight guide rails 2 are installed inside a hoistway 1.
  • a car 3 is guided by the car guide rails so as to be raised and lowered inside the hoistway 1.
  • a counterweight 4 is guided by the counterweight guide rails 2 so as to be raised and lowered inside the hoistway 1.
  • a driving machine (a hoisting machine) 5 for raising and lowering the car 3 and the counterweight 4 is disposed in an upper portion inside the hoistway 1.
