Description

Elevator {ELEVATOR}

The present invention relates to an elevator capable of providing a stable supporting force required for installing an elevator in a simple structure and thereby improving space utilization of a machine room for elevator management.

Generally, a rope-type elevator for raising and lowering an elevator car by using a rope and a hoisting machine requires a lot of space and support for its installation.

That is, an elevator car connected to the rope and a large-capacity traction machine for generating a driving force for raising and lowering the balance weight should be installed on the upper part of the elevator car of the elevator car formed inside the building, Additional installation should be done.

Accordingly, it is necessary not only to provide a space for installing the elevator device more than necessary, but also to provide various beams and nets for stably supporting the elevator car and the balance weight in the machine room at the upper part of the hoistway. You have to install many without.

In this case, there is a problem that the cost, time and manpower for installing the elevator are excessively generated, and the space of the machine room becomes narrow due to various beams and damages.
