Abstract
Description
- The present invention relates to an elevator apparatus in which a drive device (hoisting machine) for raising and lowering a car and a counterweight is arranged in a hoistway (so-called machine room-less elevator apparatus).
- Heretofore, in order to reduce the space occupied by an elevator apparatus in a building, there has been proposed a so-called machine room-less elevator apparatus in which a hoisting machine is arranged in a hoistway. In the conventional machine room-less elevator apparatus disclosed in
JP 8-208152 A - In the conventional elevator apparatus, however, since the hoisting machine is fixed to the guide rail, all of the loads of the hoisting machine, car, and counterweight are placed on the guide rail, which necessarily increases the requisite size of the guide rail. Accordingly, the increased size of the guide rails hinders space saving and a reduction in the cost of the elevator apparatus.
-
JP 01267286 A EP 0 849 209 A1 discloses a mounting apparatus for a traction machine disposed in a hoistway which includes a pair of beams that extend through the hoistway to the pit. - The present invention has been made in view of the above-mentioned problem, and therefore it is an object of the present invention to provide an elevator apparatus capable of achieving a reduction in manufacturing cost and space saving.
- An elevator apparatus according to the present invention includes: a car and a counterweight that are capable of being raised and lowered in a hoistway; guide rails arranged in the hoistway for guiding the car and a counterweight respectively; a support structure having a support column extending upwardly from a bottom portion of the hoistway, the support structure being arranged in the hoistway separately from the guide rails; a drive device having a drive sheave and supported by the support structure; and a main rope wound around the drive sheave, for suspending the car and the counterweight.
