A belt being a step belt of an escalator or a plate belt of a moving walkway comprising:
- at least one link chain arranged to circulate between a first deflecting region and
- a second deflecting region of the escalator or the moving walkway;
- a plurality of guide rollers fastened to the at least one link chain;
- a plurality of steps or plates fastened to the at least one link chain;
- a plurality of system rollers fastened to the at least one link chain, wherein the guide rollers and the system rollers are arranged among at least three tracks;
- wherein the at least three tracks are adjacent to one another with respect to a direction of circulation of the at least one link chain;
- wherein one of the at least three tracks is occupied by the guide rollers and at least two other tracks of the at least three tracks are occupied by the system rollers;
- wherein the guide rollers roll on guide rails between the first and second deflecting regions and the system rollers are free and unloaded at least in sections between the first and second deflecting regions;
- and
- wherein in the first and second deflecting regions the system rollers occupying a first track of the at least two other tracks are in engagement with a chainwheel and the guide rollers are free.
A method of modernizing an escalator or a moving walkway by replacing an existing step belt or an existing plate belt with a replacement belt comprising the steps of:
- providing the replacement belt having at least one link chain and arranging the at least one link chain to circulate between a first deflecting region and a second deflecting region of the escalator or the moving walkway;
- wherein the at least one link chain has a plurality of guide rollers fastened thereto;
- wherein the at least one link chain has a plurality of steps or plates fastened thereto;
- wherein the at least one link chain has a plurality of system rollers fastened thereto;
- arranging the guide rollers and the system rollers on at least three tracks, the tracks being adjacent to one another with respect to a direction of circulation of the link chain;
- and
- wherein one of the tracks is occupied by the guide rollers and at least two other of the tracks are occupied by the system rollers.
