Escalator

The escalator includes a truss formed of a support structure bridging a lower platform and an upper platform of the escalator, the truss including two rising sides upward from a bottom plane of the truss, the sides extending along a length of the truss and connected together by a cross-brace. The escalator further comprises a sub-frame (100) attached to an outer side of at least one side of the truss, the sub-frame being arranged to receive an outer cladding of the escalator. 自动扶梯包括由支撑结构形成的桁架，该支撑结构桥接自动扶梯的下平台和上平台，桁架包括从桁架的底平面向上的两个上升侧部，侧部沿桁架的长度延伸并且通过横撑连接在一起。自动扶梯还包括子框架(100)，子框架附接到桁架的至少一个侧部的外侧，子框架布置成接收自动扶梯的外包层。
