Values are based on 12'-0" floor-to-floor height. Adjust using factors noted for variation from
this standard.
Find rated speed in the 1st column. Select standard floor-to-floor performance time from box
under correct door type (side opening or center opening) and clear door opening width. Adjust
this time by adding factor if doors are over 7'-6" high, and adding or subtracting appropriate
amount per foot of travel over or under standard floor height of 12-0".
NOTE: All times are based on heavy duty, high speed, door operating equipment and
optimum adjustment. On geared applications with medium speed door operators, add 1.0
second. on gearless applications, add 0.5 second for less stringent requirement.
2.2.1 Scope
Division 101 of the A17.2 Manual covers the inspections made from inside the car. This
section of the A17.2 Manual is quite complete and covers the majority of the items to be
examined. However, the Inspector must also examine the inside of the car to be sure all
operating equipment is functioning in its intended manner and that the appearance of the area is
acceptable to the riders. This same consideration should also be exercised when examining
freight elevators.
2.2.2 Operating and Signalling Devices
All operating and signalling devices should be operating as intended and check to see that all
fastenings are in place and secure. The signalling devices are important to the elevator operation
because they are designed to project operating information for the purpose of expediting traffic
movement. Examples of this information are: which car is moving up or down, which car is
loading, where the car is in the hoistway, was your call registered, etc. Also, it should have
handicapped identification for operating devices that are provided and properly displayed.
2.2.3 Car Enclosure
The overall enclosure should not have loose or missing components or hardware. Handrails,
especially, should be properly secured. When something is missing or loose, total safety is
compromised. An example of this is suspended ceiling panels. Many accidents have resulted
from these not being properly installed. Another example is the securing of the service cabinet
of many main car operating panels. If this is not properly closed and locked, it is exposing car
operating controls to the general public which are, by design, restricted. The A17.1 Code
