Abstract: Personnel conveyor (2) featuring endless personnel conveyor belt (6) formed of numerous step elements (4), in which step elements (4) are attached to conveyor chains (8) along both of their sides that are driven around a first and a second reversal element, and in which conveyor chains (8) are constructed of a multitude of chain links (10) that are connected to each other at pivots (12), and where the segmentation ratio of conveyor chain (8) to personnel conveyor belt (6) is 1:1, characterized in that two chain links (10), which are equally positioned in relation to a step element (4), are connected to each other by means of a through-going connecting axle (32) attached to chain links (16) between each two pivoting points of chain links (10).

Abstract: A passenger conveyor (2) contains an endless passenger conveyor belt (6) that is composed of several interconnected footboard elements (4), wherein the footboard elements (4) are respectively connected to transport chains (8) that are arranged laterally of the footboard elements and driven around a first and a second reversing point by means of a drive. This passenger conveyor is characterized by the fact that the footboard elements (4) are detachably connected to the transport chains (8) by means of one respective lateral holding device (34).

Abstract: An escalator drive machine includes a motor output sheave which drives a drive belt along a closed look between the output sheave and a drive sprocket. The output sheave engages the drive belt with the step chain such that the step chain and attached tread plates are propelled from one landing to the other. The output sheave includes a first set of teeth and a second set of teeth. The first set of teeth is around the output sheave hub to engage a set of belt teeth extending from the drive belt. The second set of teeth is preferably located along a rim of the output sheave and is engageable with corresponding link teeth located along each link in the drive chain. The second set of teeth maintain their relationship with the corresponding link teeth due to the first set of teeth, however, there is no contact therebetween. However, should the drive belt fail or become disengaged, the second set of teeth engage the corresponding link teeth.

Abstract: An escalator system includes a protective flange assembly along edges of the steps having step flanges. In one example, a first step flange member is adjacent each edge of each step and moves with the step along the escalator path. The first panel member remains stationary relative to the step along the entire path. A second panel member is associated with a corresponding link in the drive chain and remains stationary relative to the link along the entire path of the escalator. The first panel members and second panel members cooperate to provide a continuous barrier along each edge of the steps along the escalator path.
