An arrangement is provided for monitoring at least one of raising and lowering of individual steps of a band of steps of an escalator The escalator includes guide rails for the steps, a driving gear, and endless driving chains provided in a region of balustrade bases and being driven by the driving gear. The guide rails have a transition curve from a horizontal run to a vertical run. Each step includes rollers supported on the guide rails and is held between the endless driving chains. A safety device is disposed essentially in the transition curve for switching off the driving gear. The safety device comprises a spring-activated first component positioned below the band of steps at a predeterminable distance to the continuously running steps and extending in a direction of the steps; a switch-off device coupled to the driving gear for switching off the driving gear, the first component being operatively coupled to the switch-off device; and a second component disposed in a region of the steps and being responsive to a raising or lowering of one of the steps in the transition curve for causing deflection of the first component, which deflection activates the switch-off device for switching off the drive gear.

Safety device for escalators

Roller-path system for the transportation of persons and goods, having an endless tread-plate band reversed around a horizontal axis as well as either a freely supported or a roller supported traction chain and self-supporting tread plates, each plate having two pull and two drag support-rod parts arranged close to the slate corners, respectively, opposite each other, where these plates can either directly support themselves, freely supporting rollers and the pull support-rod parts in addition to the traction chain, or can indirectly support themselves, having the pull support-rod parts mounted in traction chains with intermediate rollers and fork-shaped tread-plate resting elements which are attached by drag support-rod parts. The support-rod parts are provided as replaceably arranged system-adaptable pull and drag bolts.

Roller-path system

A safety device for passenger transporter systems for the prevention of the wedging in of foreign bodies, with a switching element, the latter serving to stop the transporter system, the switching element to be actuated from within the stationary part of the intake by means of horizontally moveable comb segments and/or a rotatably arranged carrier plate, the switching element comprises a switch which is operatively actuated via an angle lever, the latter being moved by means of a switch rod. One of the legs of the angle lever is connected with a push rod which can actuate the switch, the push rod being biased by means of a compression spring. The passenger transporter system upon displacement of at least one comb segment and/or upon lifting of the carrier plate as a consequence of pivoting about a pivot point is stopped by actuation of the switch by means of pivoting of the angle lever.

Safety device for conveyance systems for people

A device for placing escalators in and out of operation and having a system comprising safety switches, actuating elements and signal bodies. An outwardly swingable flap is provided having a rear side facing an interior of the escalator. Actuating elements for starting and stopping the escalator and monitoring elements are fastened on the rear side of the flap.
