Tread

The die-cast aluminum steps of our escalators are among the lightest escalator steps that are currently installed. Thus the aluminum content was reduced by the new computer-designed substructure by a further 1.8 k for a 1000m wide level. Weighing just less than 11kg, this is again a Geyssel contribution to our responsible use of our resources and the environment.
