Mitsubishi SP Type

Predecessor | Unknown | Successor | Mitsubishi SP-III |
Overview
SP Type was a traction elevator model produced by Mitsubishi from the 1970s until the early 1980s. Part of the SP elevator series, it was a standard traction passenger elevator model for low to high rise residential and commercial buildings, with a two-speed AC (alternating current) control method and mechanical relay control. SP Type was produced for export markets and is based on the Mitsubishi Elepet model which was sold exclusively in Japan from 1961 until 1979. It was discontinued in the early 1980s and succeeded by a newly improved SP model known as SP-II.
In Indonesia, the SP model was first sold in 1971 when Mitsubishi entered the Indonesian market through Jaya Teknik Indonesia, the former sole distributor of Mitsubishi. It was mainly installed in low to mid rise commercial, office and hotel buildings built in the 1970s and early 1980s. It is now extremely difficult to find as many of them have been modernized or replaced.
Characterictics
- SP Type elevators typically have abrupt stopping due to two-speed AC drive.
- Until the 1970s, Mitsubishi had a technical partnership with Westinghouse Electric Corp. (United States) so some features are almost similar to Westinghouse elevators. For example, the push buttons, arrival bell sound, relay controls and the "MITSUBISHI" word on the door sills are based on Westinghouse elevators.
Models
Early model (1970s)
This model was believed to be produced from 1970 until around the mid 1970s. The first installation in Indonesia was installed in 1971 when Mitsubishi first entered the Indonesian market through Jaya Teknik Indonesia as its distributor.
In 1972, a model with AC feedback control (known as "Diaglide") was launched. It is characterized by the addition of a tachogenerator that feeds back the operating speed. The controller is known as "ACEE".
Characterictics
- These elevators have thick doors, with a "MITSUBISHI" emblem on the door sills.
- Car interiors are often plain, with either painted steel or laminated walls and a centralized blade type ventilation fan.
- Landing door keyhole is an S-shaped.
- Has an overload prevention system; a buzzer will sound if the load exceeds the maximum capacity.
Fixtures
The buttons are round white which light up entirely when pressed. The landing call buttons are square glass-like buttons which light up green for up and red for down and has a metal triangle arrow in the middle. For elevators with an LOP combined with a floor indicator, the call buttons are the same as the ones inside the car. There were also square or round touch sensitive buttons with illuminating halo.
The floor indicators are mostly analog display and had two different styles; a long black display with illuminating numbers, and a set of illuminating squares with the number printed on them. Some elevators may not have an interior floor indicator, instead the floor buttons function as floor indicator. COPs have two isosceles triangles aa direction arrows.
Hall lanterns are usually triangle shaped arrows which light up green for up and red for down.

Mid-term model (late 1970s)
This model was believed to be produced from the mid to late 1970s. The design was slightly updated so it looks a bit different compared to the early model described above.
Characterictics
- Compared to the early SP Type model, the doors are now lightweight with a slimmer door sill. The "MITSUBISHI" emblem has been removed.
- The floor number on the car floor indicator changes as soon as the doors closed.
- The Mitsubishi logo and rated capacity has been combined into a single plaque above the car station.
- In some cases, the direction arrows inside the car are located on the door jamb, similar to American elevators.
- Landing door keyhole has been changed from S-shaped to a T-shaped, which continued to be used until now.
Fixtures
The fixtures remain almost the same as the older model except that the LOPs have been slightly redesigned and a different typeface (Gothic) has been applied on the floor indicators. The two arrow lamps have been removed from the COP, and some elevators have in-car lanterns located on the door jamb.
Known installations in Indonesia
- Jayakarta Plaza, Jakarta (1982, one elevator has been modernized by SAE Lift)
- Tedja Buana Building, Jakarta
- Panin Center 2, Jakarta (1980s, modernized by Mitsubishi in 2016)

Late model (early 1980s, SP-II?)
This model was believed to be produced from the late 1970s until early 1980s and is basically an improvement of the previous SP type. The name of this particular model is assumed to be SP-II.
Some changes in this model:
- Updated car interior design.
- Button and floor indicator typeface has been changed to Gothic.
- Call button and direction arrows have been changed from isosceles to equilateral triangle, and the call button arrows have been unified to black (previously green and red).
- Car floor indicator now spans the entire door width and the numbers are now smaller. Some elevators may have direction arrows on the indicator.
- Door mechanism and interlocks have been improved.
- Doors are now lightweight with slimmer door sills and the "MITSUBISHI" emblem has been removed.
This model was discontinued in the 1980s and was succeeded by the microcomputer controlled Mitsubishi SP-III model. However, the elevator design was continued to be used for freight as well as standard hydraulic passenger elevators until at least 2000.
Fixtures
The fixtures are nearly the same as before except that the buttons and floor indicators now use Gothic typeface. All direction arrows have been changed from isosceles to equilateral triangle. The car floor indicator now spans the entire door width.

Known specifications
Very little is known about the specification of Mitsubishi SP Type model due to lack of valid sources and official publications. It is believed that the capacity range is between 450 and 1000 kilograms (or between 6 and 15 persons). The speed is typically 1 meters per second, it is unknown if higher speed options were available. Door type was available in regular center opening and two speed telecopic.
