Disabled passenger Lift are actually a type of ordinary passenger elevator. They must comply with national barrier-free design standards and can be safely and conveniently used by people with disabilities (especially those in wheelchairs) as well as the elderly, children, pregnant women and other people with mobility difficulties. In simple terms, it refers to a regular passenger elevator that meets accessibility standards.
The design of disabled passenger Lift must meet the following requirements
1. Design of elevator car
● Sufficient space: This is the most basic requirement. The cabin must be spacious enough for a wheelchair to enter and be able to rotate 360 degrees inside.
● Appropriate door opening width: The clear door opening width of elevator doors is usually required to be no less than 800 millimeters (0.8 meters) to ensure that most wheelchairs can enter easily.
● Rear wall mirror of the car: A mirror is installed on the rear wall. This can help people in wheelchairs see the situation behind them clearly without straining to turn around, making it convenient for them to observe whether they have fully entered the cabin and stepped back to leave the elevator.
● Low-position operation panel: The height of the button panel should be suitable for wheelchair users. Generally, the height of the topmost button should not exceed 1.1 meters. The buttons should have Braille markings and clear numbers.
● Side wall handrails: Three sides of the cabin should be equipped with firm handrails at a height suitable for standing people and those with mobility issues to hold onto.
● Voice floor announcement system: When the elevator reaches a certain floor and opens the door, it clearly announces the floor number in voice, providing convenience for visually impaired people.
● Clear visual information: The floor display numbers should be large enough, clear and easy to read.
2. Design of the elevator hall
● Barrier-free waiting area: There should be sufficient turning space in front of the elevator hall to facilitate the turning of wheelchairs.
● Low-position summon button: Similar to the buttons inside the cabin, the up and down buttons outside the hall should also be installed at a lower position (usually 0.9-1.1 meters above the ground) and marked with Braille.
● Clear floor display and sound prompt: There should be a clear floor display and sound and light prompt for arrival outside the hall door, so that both hearing-impaired and visually impaired people can sense the arrival of the elevator.
3. Operational performance
● Smooth operation and stopping: The start-up, operation and stopping of the elevator should be as smooth as possible to avoid violent shaking and shock, which is crucial for passengers who have difficulty standing steadily.
● Sufficient door opening and closing time: The opening and closing time of the elevator door should be set relatively long, and the closing speed should be gentle, providing passengers with slow movement sufficient time to enter and exit. Many barrier-free elevators are also equipped with light curtains or safety touchpads that can reopen the door when an obstacle is detected
