MCE SmarTRAQ - Measuring Closing Force; Parameter Examples and Closing Time Compliance

Measuring Closing Force

Parameter Examples
The following table provides sample initial values for your information if needed.
Measuring Closing Force
To measure door closing force:
1. Park the car at a floor.
2. Begin to close the doors. Allow them to close 1/3 to 2/3 of their normal travel, then stop
them.
3. Insert a force measuring device appropriate to measure 30 lbf against the stopped door.
Slowly release the doors so that they are now held stationary by the measuring device.
4. Slowly back off on the device until the door just starts to move. At this point, the door
and measuring forces are approximately equal and the closing force value may be read.
Door Closing Time Compliance
Note
Maximum adjusted door closing speed is approximately 75% of adjusted opening speed.
If you are installing a job in a jurisdiction requiring compliance to Requirement 2.13.4.2.4 of
ASME A17.1-2000/B44-00 or later, you must apply one of the Door Data Plate labels included
with this manual to the door operator or crosshead. The data tags must be properly completed
to show:
• Month and year of installation
• Typical floor door mass
• Minimum code closing time (resulting in average kinetic energy of less than 7.37 foot
pounds) at normal closing speed with typical floor door mass
• Minimum code closing time (resulting in average kinetic energy of less than 2.50 foot
pounds) at reduced/nudging closing speed with typical floor door mass
• Heavy door mass (where applicable) and landings affected
• Minimum code closing time (resulting in average kinetic energy of less than 7.37 foot
pounds) at normal closing speed with heavy door mass
• Minimum code closing time (resulting in average kinetic energy of less than 2.50 foot
pounds) at reduced/nudging closing speed with heavy door mass
