  • This traction system uses a hoisting machine in which a car is placed in a hoistway formed in a building, a counterweight having substantially the same mass as this is provided, and the car and the counterweight are suspended by a main rope. By winding up the main rope, the car and the counterweight move up and down in the opposite direction.

  • This large hoisting machine is disposed in a machine room provided at the top of a hoistway in the elevator apparatus.
  • Such a hoisting machine is configured to be fixed to a machine beam constituting the machine room via vibration damping rubber. Since the hoisting machine is installed in the machine room, an installation member such as a machine beam is used.
