A 10,000-pound elevator motor that shuttled hundreds of people a day at the original World Trade Center will be part of the National September 11 Museum’s permanent exhibit when it opens in 2013.
The exhibit will also tell the story of John Menville, who arrived at the World Trade Center in 1969 to install the elevators and stayed for 32 years to maintain them.
On 9/11, thousands of people, including Menville, used the elevators to evacuate. When the first plane hit, Menville’s immediate thought was of how long it would take to repair the elevators.

Ascending Car Overspeed and Unintended Car Movement Protection - Section 2.19
The Code
All newly installed electric traction elevators are required to have a means to stop the car in the event of an overspeed in the up direction and to keep the car from moving when movement is not intended. With respect to ascending car overspeed (ACO), the intent is to prevent the elevator car from from striking the hoistway overhead structure. With respect to unintended car movement (UCM), the intent is not to permit the elevator car to move when the car and hoistway doors are not closed and locked. This code is defined in ASME A17.1-2000/4/7, Section 2.19. The device required is referred to as an "emergency brake."
All altered (alteration, modernization) electric traction elevators must meet this requirement as well, provided the alteration includes one or more of the following:

Elevator Inspections and Maintenance - Were they performed?

I reported about an elevator incident in Ames, Iowa and today we post a follow-up about this elevator shaft fall and “accidental death” at Campustown in Ames, Iowa. First let's look at an elevator incident in Las Vegas and then a CNBC Report that discussed elevator maintenance and inspections. If you watch the entire news clip you will wonder about whether inspections are actually performed as they are supposed to be and is maintenance being properly and timely performed? In these economic times are landlords attempting to save costs by doing limited inspections? Couple that with the Ames Police Department investigation report and photographs not being publicly release and you'll be forced to ask, why not?
