Abstract

A support construction for an escalator or moving walkway comprises at least one framework element integrally constructed as a flat, non-profiled, cut plate. Multiple framework elements can be assembled into a unitary support construction. By virtue of the simple structure of the support construction. Wherein little welding work is needed, production time for the support construction is substantially reduced over conventional constructions.
