Machine-room-less elevator installation structure with traction machine mounted at a rooftop

摘要

The present invention relates to an installation structure for mounting an elevator traction machine at a rooftop floor being capable not only to distribute a concentrated operating load generated on the elevator traction machine during elevator operation over the guide rail to the bottom of a pit through the installation structure members, but also to remove a conventional machine room separately located at the upper end of a shaft and to minimize an installation space of the elevator traction machine without altering an operating height of elevator.
