Definitions

  • the present invention relates to a machine room-less elevator in which a hoisting machine is disposed at an upper portion in a hoistway.
  • the counterweight guide rails are as close as possible to the car guide rails. And in order to avoid that a car suspension car and a main rope interfere with balance weight, the notch is provided in the end part of the width direction of balance weight (for example, refer patent document 1).
  • the thickness dimension of one end in the width direction of the counterweight is reduced by providing the notch. For this reason, the dimension of the vertical frame provided at one end in the width direction of the counterweight becomes smaller, and the cross section coefficient of the vertical frame becomes smaller.

Abstract

La présente invention concerne un ascenseur sans salle de machines, la région de levage pour un contrepoids étant disposée sur le côté de la région de levage pour une voiture, comme cela est vu depuis un palier. Un second rail de guidage de contrepoids est disposé plus près d'un second rail de guidage de cabine qu'un premier rail de guidage de contrepoids. Une seconde poulie de cabine est disposée sur le côté du second rail de guidage de cabine, comme cela est vu depuis le palier. Comme cela est vu directement du dessus, l'extrémité d'une poulie motrice sur le côté de la seconde poulie de cabine est disposée dans la même position que le second rail de guidage de contrepoids dans la direction avant-arrière de la cabine.
