Elevator Full Door Protection & 3D

Many of the buildings we maintain have replaced their safe edge door protection with door scans but we still stumble across a few that have not.  If you still have a safe edge, get it replaced!

What is a elevator safe edge?  An elevator safe edge is a “boot” that is on the leading edge of the elevator car door that will come into contact with an object and retract when it hits someone or something.   This piece of technology and equipment worked very well for many years.  The issue with this device is that it physically needs to hit something before it retracts and over the years the adjustment on the microswitch which is the component that tells the elevator door to reopen may be worn out.   As elevator door operators get older we lose the ability to adjust door speed to be reliable and safe.

What is a door scan/full door protection unit?  A door scan/full door protection unit is a device that works just like your device that prevents the garage door from hitting your car when it is going out of a garage.  The elevator door protection unit has beams that go up and down the length of the elevator car door.  If the device detects and obstruction in the elevator car doors path it will reopen the door before hitting the person or object.

Why replace the safe edge?  One of the most common “accidents” or cause of injury in elevators is the door hitting people.  This device can be replaced for a reasonable cost and it will reduce the possibility from someone getting hit by the door.

How long does a full door scan last?  We have been installing door scans for quite some time, some last 5 years and some last 20 years depending on how much use the elevator gets and what kind of use the elevator gets.  I would ball park that the average door scan will work 10-15 years.  The door scans are electronic and do get hit and jarred during the use of the elevators.

How much does a door scan cost?  Call your elevator maintenance provider, a door scan should cost anywhere between $1,500.00 to $3,000.00 to install.  This device is well worth the investment.

3D door protection – There are newer 3D devices that can provide additional protection.  The devices are not perfect but they do have some really good benefits.  The 3D door protection device is great for any building with slower moving people or children.
