Escalator with heavy-load step chain segmented fixing device

The invention discloses an escalator with a heavy-load step chain segmented fixing device. Heavy-load step chains are fixed to a plurality of guide rails in a segmented manner, two ends of each heavy-load step chain are connected with channel steel on two sides through a connecting piece, and stress of the chains is dispersed to a truss. The escalator with the heavy-load step chain segmented fixing device has the advantages that the stress of the chains is dispersed to the truss, the chains are prevented from sliding out of the guide rails, and the transportation safety is improved. 本发明公开一种带重载梯级链分段固定装置的自动扶梯，重载梯级链分段地固定于多个导轨上，每个重载梯级链的两端通过一连接件与两边的槽钢连接，链条的受力分散到桁架上。本发明的优点是链条的受力分散到桁架上，避免滑出导轨，提高了运输的安全性。
