一、概述中间驱动自动扶梯的一大特点,是能以组合的方式用多台机组驱动同一台自动扶梯。这种多级驱动的新型结构形式,使自动扶梯的能耗,受力状况,结构重量等性能指标,较之传统的上端驱动自动扶梯,有了一定幅度的降低。同时,使自动扶梯的安装高度能够根据需要灵活地变化。特别是对某些建筑设施所要求的大高度自动扶梯,其优点更为显著。 I. Overview One of the major features of the mid-drive escalator is the ability to use multiple units to drive the same escalator in a combined manner. This new type of multi-stage driving structure makes the performance indicators of energy consumption, stress conditions, and structural weight of escalators lower than the traditional upper-end driving escalators. At the same time, the installation height of the escalator can be flexibly changed as needed. Especially for large-scale escalators required by certain building facilities, the advantages are even more pronounced.
