Elevators are used by thousands of people every day. Responsible building owners all over the world are doing their part to keep people safe by upgrading their existing vertical transportation equipment to meet all local and national safety codes.
|
|
New door safety systems use electronic micro-light/infrared beams that cover the doorway of the elevator. When the beams are broken, the doors retract. Unlike old mechanical systems, the new doors do not come into contact with either passengers or objects.

| Jack packing is the gasket that provides a seal on the jack head and prevents oil from leaking into the elevator pit. |
| |
|
The pit safety kit includes a pit ladder, pit work light, and pit stop switch to meet national codes, reduce the risk of injury, and provide a safer working environment. |

|
Safety
tests on all elevators require weights equal to the full weight
capacity of the elevator be loaded and the elevator’s braking
systems checked and evaluated. |

|
The cylinder of a typical
hydraulic elevator is installed in the ground beneath the elevator
car where it is exposed to the risk of corrosion and electrolysis.
These cylinders may leak oil, contaminating the environment and
endangering passengers.
The ASME A17.1-2000 National Elevator Safety Code has a new provision that
requires single-bottom cylinders be replaced with double-bottom cylinders
or be equipped with code compliant safeties. |

Swing
door guards are manufactured from formed sheet metal bolted to
a swinging hoistway door to block the space between the door
and a scissor-type elevator car door. The space must be no more
than 4" with a scissor gate and
5 1/2" if the elevator car has a door. |

|
A shutoff valve manually
disconnects the oil flow from the tank to the oil line to allow
maintenance. An overspeed valve stops an elevator car from rapid,
uncontrolled descent, thus protecting against oil supply line failure
between the valve and the power unit. |

|
Braille and code signs
are required by national codes for use in and around elevators
to provide visually impaired passengers with crucial information,
such as direction, position, exit, and emergency protocol. |
