Overview
SP-II was a model of standard passenger elevator model produced by Mitsubishi between the late 1970s and mid 1980s. It was a two-speed AC feedback traction model designed for low to mid rise residential and commercial buildings, and aside from being a successor of the original SP Type model in the 1970s, is also an improvement of it. Major improvements on this model are the use of AC feedback control method with a digital speed detection to improve ride comfort and leveling accuracy, door mechanism and interlock, and updated car interior design with decorative steel panels and downlights. It was based on the late-term Mitsubishi Elepet model in Japan.
Chronologically, SP-II was the second model of Mitsubishi SP, a series of standard passenger elevator model for export markets that was sold from the 1970s until the early 1990s. Production began in 1979 and by 1983 it had been sold in 54 countries across the world[1], including Indonesia. It was discontinued around the mid 1980s and succeeded by the Mitsubishi SP-III which began sales in 1983. SP-II was also the last relay controlled passenger elevator model produced by Mitsubishi as its successor used microcomputer controls.
In Indonesia, this model was mainly installed in small to medium sized commercial/office buildings as well as hotels built in the early 1980s. It is now extremely difficult to find as many of them have been replaced.
Characteristics
Compared with its predecessor, SP-II has several characteristics such as:
- The floor buttons and indicators use a Gothic typeface.
- Call buttons and direction indicators now use equilateral triangles (previously isosceles triangles). In addition, 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.
- Doors are now lightweight with slimmer door sills. The "MITSUBISHI" emblem is no longer present.
- Ceilings now have an electric fan, often integrated with the central light in the middle.
Known specifications
Very little is known about the specification of SP-II. The capacity range was available between 450 and 1000 kilograms, and the speed range was between 0.75 and 1.75 meters per second. Doors were available in center opening type in most cases.
Fixtures
Except for some updates, the fixtures used in the Mitsubishi SP-II elevators are nearly the same as the previous SP Type elevators.
Buttons
The buttons remained the same as the previous SP Type model which are round white that light up entirely when pressed, but the typeface has been changed to a Gothic type. In addition, the direction arrows have been changed from isosceles to equilateral triangle. Some installations had black buttons with illuminating number in the center.
In some cases, the landing call buttons on the main/ground floor are square glass-like button with a metallic triangle in the center, similar to the SP Type elevators. These buttons light up green for up and red for down.
Floor indicators
The car floor indicator now spans the entire door width. As mentioned before, the typeface has been changed to a Gothic type and direction arrows are now equilateral triangles.
In some cases, the landing floor indicators on the main/ground floor are located above the landing door and analog type consists of illuminating clear squares with the number printed on them.

- Although SP-II was discontinued in the mid 1980s, the elevator design was continued to be used for freight as well as standard hydraulic passenger elevators until at least 2000.
