I want to add an elevator without a machine room on the roof

A compact winch that can be stored inside the elevator shaft has been realized

A sightseeing elevator that provides a comfortable space

In recent years, sightseeing elevators can be found everywhere in the city. Some of them are installed on the platform and plaza of the station, so they are easy to see compared to conventional elevators, and do not make people feel oppressive. In addition, it does not give the elevator users a sense of occlusion, and can provide a comfortable space. At the same time, because you can see the inside of the elevator, the monitoring of cameras and security guards is more effective, and it also has advantages in terms of safety. Recently, it has been widely used in monumental buildings, and many high-rise buildings and buildings with historical roots around the world have been renovated and renovated with sightseeing elevators. In order to realize a sightseeing elevator that combines many features and advantages like this, it is necessary to incorporate a lot of technology.

This is a sightseeing elevator that is not only designed, but also easy to monitor and safe

Miniaturization is achieved by a small AC permanent magnet motor + gearless winch, and there is no need for a machine room

For example, when installing sightseeing elevators in some long-established high-rise buildings, it is often encountered that it is not possible to set up a special elevator machine room on the roof. That's where the gearless winch with built-in AC permanent magnet motor, developed by Nidec KINETEK for elevators, comes in handy. Thanks to the use of rare earth magnets, it has both the torque to fully drive the winch and the miniaturization of the motor. Since there is no need for reduction gears, the entire winch can be miniaturized and there is no need for a machine room on the roof, and the winch can be installed inside the elevator shaft (elevator lifting path). In addition, the idea of using steel belts instead of conventional wire ropes also contributes to the miniaturization of elevators. According to the United States Society of Mechanical Engineers (ASME) elevator standard, the diameter of the winding pulley must be more than 40 times the diameter of the wire rope. When the diameter of the wire rope is 12.7mm, the diameter of the pulley should reach 508mm. Replacing the wire rope with a thin steel belt is both compliant with the standard and can be miniaturized to ensure the necessary maximum load bearing and the required friction when winding.

The entire winch has been miniaturized, so there is no need for a machine room, and elevators can be installed in high-rise buildings with historical roots without changing their appearance
