People mover () comprising an endless tread belt () formed from several tread elements () connected to one another, which is driven by a drive unit about a first and second reversal point (), and a side skirt () moved along with tread belt (), the side skirt () comprising flange elements () joined to the tread element () and bridge elements () connected movably relative to flange elements (). A sensor () is arranged adjacent to the side skirt (), the sensor () having a limited detection range perpendicular to the circulation direction of side skirt (), and a plurality of marking elements are arranged in a line on side skirt () along the circulating direction having a limited width perpendicular to the circulating direction.

Safety monitoring system for a people conveyor

Comb plate () for a passenger conveyor () with a conveyor band and a moving flange a number of teeth () arranged on it essentially parallel to one another across the width of the conveyor band, which mesh in use with grooves () provided on the upper surface of the conveyor band characterised by a deflector guard () which is arranged at the lateral edge of the comb plate () and extends a certain height above the upper surface of the comb plate ().

Comb plate for passenger conveyor with moving flange

Passenger conveyor () including an endless conveyor band () connected to a drive chain () at each lateral edge thereof and driven by a conveyor band drive () including an electric motor () and one drive output device () at each lateral edge of the conveyor band () for driving the respective drive chain (), characterised in that the conveyor band drive () is arranged laterally outside of the conveyor band ().

Passenger conveyor drive machine

A passenger conveyor () with a running belt () contains a frame (). A main running belt drive () is mounted on the frame () and contains a drive shaft () and at least one running belt driving wheel that is connected to the drive shaft. A drive unit contains a driving motor () and a step-down gear (). The output of the step-down gear () is connected to the input of the main running belt drive (). The driving motor () is mounted on the housing () of the step-down gear (), with the driving motor () and the step-down gear () forming a drive unit (), and the drive unit () is supported by the main running belt drive ().

Drive unit for escalators or moving sidewalks

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

Chain segment for personnel conveyor

A passenger conveyor () contains an endless passenger conveyor belt () that is composed of several interconnected footboard elements (), wherein the footboard elements () are respectively connected to transport chains () 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 () are detachably connected to the transport chains () by means of one respective lateral holding device ().

Footboard element fastening for passenger conveyors

A control system for a passenger conveyor includes a ready-to-operate mode, a standby speed and a nominal speed. A method to operate the passenger conveyor includes the steps of: transitioning the conveyor from ready-to-operate mode to nominal speed using a frequency converter; switching from frequency converter to line power at nominal speed; switching back to frequency converter if no passengers are present and transitioning from nominal to standby speed; and transitioning from standby speed to ready-to-operate mode if a predetermined amount of time passes without a passenger entering the conveyor.

Variable speed passenger conveyor and method of operation

An hydraulic buffer or brake is provided on an escalator to stop movement of the steps in case power is interrupted, or if a safety device is activated. The braking action occurs in parallel to the inclination of the step chain. The braking action occurs in several stages so that a maximum time delay between initiation of the device and stopping of the steps can be achieved. In the first stage, the braking force is more solely applied, so that the first stage can affect a stopping of an empty escalator when completed. In the second stage the braking force is more quickly applied, so that the first and second stages can affect a stopping of a heavily loaded escalator in concert in the same maximum deceleration as the first stage can, when completed stop the lightly loaded escalator.

Escalator step buffer

The handrail of an escalator of other passenger conveyor is driven by traction rollers which engage the handrail and also directly engage links which are connected to and drive the steps or tread of the conveyor. The handrail is biased into engagement with the traction rollers, and moves at substantially precisely the same speed as the steps or tread due to the direct connection between the step or tread drive and the handrail drive.
