The present invention relates to an arrangement in the drive machinery of a travelator, moving walkway, escalator or similar and a method for changing the drive belt of the handrail belt of the handrail incorporated in a travelator or similar. In addition to the drive machinery (1), the travelator or similar of the invention comprises at least one handrail (13) with handrail belt (12), and which drive machinery (1) comprises at least a drive motor (2), a support element (10) for the handrail belt (12) and a drive belt (8) connecting the rotational movement of the drive motor (2) to the support element (10). The support element is a supporting wheel (10) of essentially large diameter fitted to be used by the drive belt (8). With the method according to the invention the drive belt (8) is placed into position by fixing the drive belt (8) to the installation groove (14) on the supporting wheel (10) and rotating the supporting wheel (10) such that the drive belt (8) is placed into position around the supporting wheel (10). The support element of the handrail belt (12) of the handrail (13) of the travelator, moving walkway, escalator or similar according to the invention is a supporting wheel (10), which contains a coupling element (14) for coupling and installing the drive belt (8) of the supporting wheel (10) onto the rim of the supporting wheel in connection with placing the drive belt (8) into position.
(ZH) 本发明涉及活动人行道或类似设备的驱动机械中的装置和用于更换活动人行道或类似设备中的扶栏的扶栏带驱动带的方法。活动人行道或类似设备包括至少一部带有扶栏带的扶栏，驱动机械包括至少驱动电机；支承构件，用于扶栏带；和驱动带，将驱动电机的旋转运动连系于支承构件。支承构件是大直径支承转轮，配装得由驱动带予以利用。按照本发明方法，驱动带是通过将驱动带固定于支承转轮上的安装槽沟并转动支承转轮以使驱动带围绕支承转轮被安放就位而予以安放就位的。活动人行道或类似设备的扶栏的扶栏带支承构件是支承转轮，其包含联接构件，用于结合将驱动带安放就位而将支承转轮的驱动带联接和安装到支承转轮的轮缘上。
