I discussed this topics with MELINA concern.
We think that HUMBEL gear can apply for type SAJ escalator
in the future.
However, we should do an enough evaluation because speed reducer
is a key component of the escalator.
Speed reducer of MFK already has the operation results
for 20 years or more.
If we apply HUMBEL gear for our escalator,
we have to do evaluation in laboratory and field trial.
We think that it takes 2-3 years for the evaluation.
Therefore, I think that the adoption is difficult at once.
At the first, it is important to complete the prototype for
adopt it in several years lator.
