至今該大樓的所有電梯己被翻新

除左一架仍然翻新驅動

另有一至兩部被翻新牆身

呢部lift既ac三速機變左vvvf機

[bearchoirfan]

最近至更換驅動機芯？

By the way，要判斷是否 VVVF 機，可以用一部中波（AM）收音機，調較去 1000 -1600kHz 是但一個頻道，當電梯閂門之後聽到好似機器聲o既聲波由收音機播­出，部機就係 VVVF。

1. Where's 2 in this building?

2. Were any of the 15-23 elevators modernized?

Level 2 is allocated to the shopping mall area and is accessible by dedicated escalators. The high speed elevators calling at levels 15-23 still remain original today without any modernization.
