Is it comb plate or combplate? It seems the industry can’t make up its mind on this term. You’ll find it listed both ways across the industry, and even listed both ways in the same document!
Regardless, the comb plate impact device is a very important safety feature of an escalator, and has been required per ASME A17.1 Safety Code since the early 1990’s. Detection of either vertical or horizontal movement in a comb plate is vital for the safety of the riding public.
KONE Spares has two different upgrades for this device, and a tool to make sure this feature is adjusted properly — no matter what brand or model escalator you’re working on.
For older Montgomery HR Series escalators which don’t have the comb plate impact safety feature, we have a kit to add it to the escalator: Comb Plate Impact Device Upgrade for Montgomery HR Series Escalators
For Montgomery HR Series escalators which do have the comb plate impact device feature, we have a reliability upgrade: Escalator Comb Plate Impact Device Spring Reliability Upgrade
And if you’re working on any escalator with a comb plate impact safety device feature, we have this tool to help you adjust it to proper spec: Escalator Comb Plate Impact Fixture Test Kit
We can’t stress enough the importance of a working, properly adjusted comb plate impact safety system on an escalator. The health and well-being of the riding public depends on it.
