Lego Technic Escalator designed by Takanori Hashimoto

When I build Lego Technic sets, several technic designs I always dream to build one. One of my dream Lego Technic sets is Lego Technic Escalator. This transportation is common in our daily life. However, I always feel curious on how it works.
In the process of building this Lego Technic Escalator, I understand the mechanism behind this interesting machine.
After examining different designs on this issue, I found the most brilliant one is designed by Takanori Hashimoto, a Japanese Lego expert of Lego GBC. Two years ago, I tried to translate my message to Japanese and sent an email to Mr. Hashimoto, asking him to send me or to sell me the instructions. However, he replied me that he did not write any instructions at that moment.
Two years have passed by, the instruction is drawn already. I build this awesome Lego module finally.
In this video, it records different steps of building this set. I make a little amendment of the original design to ensure the smooth running.
Hope you enjoy my sharing!
