Predecessor Unknown Successor Mitsubishi High Rise Elevator (1990s)

This article is about an unnamed Mitsubishi high speed elevator model that was produced between the 1970s and 1980s.

Overview

Gearless motor of a 1970s Mitsubishi high speed elevator in Jakarta.

These high speed Mitsubishi passenger elevators were produced between the 1970s and 1980s at the Inazawa Works factory in Japan, and was designed primarily for high rise buildings like offices and hotels. They use DC (direct current) gearless motors and group control system. Until the mid 1980s, the model used Ward Leonard drive system and relay controllers before they were succeeded by Thyristor drive system and microprocessor controllers.

In Indonesia, these elevators were installed in high rise office buildings in Jakarta that were built in the 1970s and 1980s. Nearly all of these installations no longer exist as they've been replaced or modernized. As of 2024, the only known original installations still remain in Indonesia are at The Landmark Towers in Jakarta.

Characteristics

  • These elevators are typically fast with quick leveling.
  • Arrival chime is a "Westinghouse" bell chime for 1970s model, and a distinctive acoustic sound for 1980s model.

Known specifications

Very little is known about the specifications of these elevators.

The group control system applied in this model is Mitsubishi's OS series. Known series are OS-75E (1970s) and OS-2100/0S-2100C (1980s).

Until the mid 1980s, the model used Ward Leonard drive system with motor generator sets, as well as relay controllers (known series names are TFNL and TFHL). This was changed in the mid 1980s with Thyristor drive system and microprocessor controllers.

Fixtures

The fixtures are nearly the same as the ones used in the Mitsubishi SP Type standard passenger elevators.

Standard buttons

The buttons are round white which lights up entirely when pressed, and have black halo. For the call buttons, they are square glass-like buttons which light up green for up and red for down. Door open button always has green words, while the alarm button is always yellow.

Touch sensitive buttons

These are silver square buttons with illuminating halo. The door control and alarm buttons are the standard push buttons (see above).

Floor indicators and hall lanterns

Many older elevators from the 1970s use analog floor indicators with a set of illuminating squares. Some 1980s elevators use digital segmented displays.

Hall lanterns are typically triangle shaped which light up green, red or creamish white. Custom shaped hall lanterns also existed.

Known installations in Indonesia

All of these installations are in Jakarta unless otherwise stated.

  • Jakarta City Hall - Block G, Jakarta[1] (1976, now modernized)
  • Badan Pengkajian dan Penerapan Teknologi - Soedjono Djoened Poesponegoro Building, Jakarta (1976-2016, replaced into Sigma elevators)
  • Wisma Antara, Jakarta (1980, modernized)
  • Graha Mandiri, Jakarta (1982, modernized in the early 2000s)
  • Menara Multimedia, Jakarta (1984, modernized by Lift Munich)
  • The Landmark Tower A & B, Jakarta (1985 and 1991)
  • International Finance Center 1, Jakarta (1984-2019, building demolished)
