Building Technology And Utilities Practice Test

Which component is the hollow metal structure that holds the track in the escalator system?

Tracks Comb Plate Comb Lights Truss

Correct Answer:

Truss

Explanation:

In escalator construction, the hollow metal frame that carries the track along the length of the unit is the truss. This structural skeleton provides the primary support, keeps the track and steps aligned, and distributes loads across the escalator structure. The tracks themselves are the rails the steps ride on, not the hollow support frame. The comb plate sits at the entry/exit to seal gaps and work with the comb teeth, while comb lights are lighting fixtures near those areas. So the hollow structural member that holds the track is the truss.
