| (54) | Cable guide and drive machinery position for elevator |
| (57) There is described an elevator system which can be installed in a shaft accommodated
within the height of the top floor of a building and in which a hoisting machine can
be disposed within the shaft. A couple of turning pulleys for changing a main cable
extending between a car and a counterweight from a vertical direction to a horizontal
direction are provided in a space between the edge of the car and the interior wall
surface of a shaft. A hoisting machine on which a drive sheave is provided in a rotatable
manner such that the rotor axis of the drive sheave is oriented vertically is provided
at the upper end of the shaft, such that the lower end of the hoisting machine is
located at a position higher than the lower edges of the turning pulleys. As a result,
the hoisting machine can be disposed in the shaft accommodated within the height of
the top floor of a building, and the main cable can extend between the car and the
hoisting machine. The elevator system can be installed within the shaft accommodated
within the height of the top floor, thereby diminishing construction cost required
for ensuring a space for installing the elevator system. |
