My company just picked up a building with Thyssen escalators. I believe they are cascata ft722. Definitely 90s vintage. Are there any fault books/ maint manuals out there I might be able to get? Are faults the same as the 800/900 series? I cant seem to find any information on them. Luckily, I found a parts book buried in my archives though so thats good. Thank you for your help!
