INFORMATIONAL VIDEO: MONTGOMERY HR SERIES COMBPLATE IMPACT DEVICE UPGRADE
The combplate impact device has been a required safety device per ASME A17.1 Safety Code for Elevators & Escalators since the early 1990’s. KONE Spares has developed combplate impact upgrade kits for all Montgomery HR Series escalators model types manufactured from the 1960’s thru the early 2000’s.
To learn more about this upgrade and why it’s an important safety feature, we invite you to watch this short informational video excerpted from our NAEC 2020 presentations:

KONE Spares Missing Step Detector Upgrade
Are you tired of false stops and replacing worn out missing step detection sensors? If your answer is yes, then check this out:

These proximity sensors don’t make any contact with the escalator – at all.
No contact = NO WEAR AND TEAR
No wear and tear means fewer replacements.
This is the KONE Spares Missing Step Detector Upgrade.
- Can be used as an upgrade for Montgomery escalators that were shipped with the old roller-type missing step detector device
- Fits most escalators, not just the Montgomery HRs
- Improved reliability

COMB PLATE IMPACT AND ESCALATOR SAFETY

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.
ER-1225 and ER-825 Permanent Magnet Spline Brake Upgrades for Montgomery HR Series Escalators

All maintenance providers that service Montgomery HR Series escalators are encouraged to replace existing ER-1225 and ER-825 pin drive brakes with the recently developed spline brake replacements.
- More Robust
- More Reliable
- Longer Lasting
- Vibration Resistant
- Interchangeable in Form, Fit, and Function
- Available With or Without Sensors
The permanent magnet spline brake is designed to gradually stop the escalator and hold it stationary under full load. This brake includes a closed-loop brake circuit within a solid state and/or microprocessor controller and is designed to meet current ASME – A17.1 Code deceleration rate requirements, and operates in conjunction with a velocity feedback encoder and/or tachometer.
The component parts of the spline and pin armatures are considered interchangeable in form, fit and function; therefore the existing tachometer and/or encoder and brake control system may be reused. The brake voltage must be adjusted per the installation instruction to achieve the proper armature setting.
Both the ER-1225 12″ Spline Brake and the ER-825 8″ Spline Brake are available with or without sensors.
