- For the predecessor model, please refer to Mitsubishi GPM.
The Mitsubishi Series GPM-III was Mitsubishi's conventional gearless traction elevator model for low to high-rise buildings which was marketed in 1997[1]. It was sold for overseas markets as well as United States. It was most likely a successor of Mitsubishi GPM. This model was also produced by Shanghai Mitsubishi. It has 3 variants, which are the regular GPM-III, GPM-3M and GPM-3H.
In the United States, GPM-III was made from no later than 2008 until 2018 when it was replaced by Diamond HS.
Overview[]
Overseas[]
Mitsubishi GPM-III is a gearless traction elevator for high rise buildings. It uses inductor motors with 10% smaller sheave which saves machine room space. The controller is equipped with Associated Management Logic (AML) VLSI. It is specially designed for two AI (Artificial Intelligence) supervisory systems; AI-21 for two to four cars and AI-2200N for three to eight cars in a group control.
A variant of this model for modernization of older Mitsubishi high rise elevators is known as GPM-IIIMZ.
GPM-III was succeeded by NexWay High Speed in October 2002[2], which is the current model for the high rise segment. Similarly, the GPM-IIIMZ variant was succeeded by NexWay Modernization.
United States[]
In the United States, GPM-III is a gearless high-rise elevator model with Artificial Intelligence (AI) supervisory systems; AI-21 for two to four cars and AI-2100N for three to eight cars in a group. It is also equipped with Data Network Systems. The latest version of GPM-III uses new AI systems; (Sigma)AI-22 for two to four cars and (Sigma)AI-2200C for three to eight cars in a group. It also support DOAS-S as optional feature.
There are two types of traction machines used on this model. One is a worm gear machine (model GPM-3LU) and two is a gearless machine with permanent magnet motor (model GPM-3MU). Worm gear machine is only used on elevators with speeds of 200 and 350 FPM. The gearless machine with permanent magnet motor is only used for elevators with speeds of 400 FPM and higher, as well as capacities of 2500-3500 LBS.
Unlike the overseas version, GPS-IIIMZ (modernization version) was not available in the United States. This is because the model did not meet ASME codes.
The American GPM-III model was discontinued and replaced with the new Diamond HS model in December 2018.
