Types of lift doors

Introduction

There are many different types of doors that can be installed in lifts, all of which can be divided into manual and automatic. Manual doors are usually opened and closed manually by the user, while automatic ones are powered by a door operator. Both manual and automatic doors can be further subdivided into different categories.

Manual doors

Typically found in older buildings, these lift doors are normally operated by the user, although some close automatically. They are most common in older and small European lifts dating back to the 1950s and 1970s.

In some cases, the door can be spring-loaded, meaning the gate cannot be left open, or the gate might close automatically when the user presses the button and partially or fully open when the lift arrives at a floor.

Automatic doors

These types of lift doors are considered the standard in modern buildings. Nearly all automatic doors are powered by a door operator in the cabin and can be found in a wide variety of locations, such as retail stores, schools, hospitals, airports, and shopping centres. Automatic doors offer many different features that manual doors do not, including traffic sensors, pressure sensors, speed controls, and obstacle detection.

They can also have different types of opening. Single opening refers to a single panel door the width of the doorway that opens to the left or the right. It is popular in older buildings across North America. Centre opening doors are common in many buildings; they have two panels that meet in the middle and slide open to the side. These types of doors are highly efficient but do not allow for the full use of the door width.

Swing doors

Swing doors are commonly installed for pedestrian use. They can open and close automatically and are easily installed in residences and other similar buildings. Swing doors come in a variety of styles:

Telescopic sliding doors

Telescopic doors are usually found in small spaces, as their opening mechanism does not require the doors to slide all the way through the side walls. The doors open and retract, requiring less interior wall space and providing a larger automatic opening than traditional lift doors. Telescoping swing doors can have different styles:

Sliding doors.
Central opening or panel opening.
Stainless steel doors.
Glass doors.
Fire rated doors.

Eco bus folding doors

These doors are typically installed when both weight and space are limited. Eco bus folding doors do not change the weight of a lift or its cabin structure, due to their reduced dimensions and folder opening. An integrated mechanical release system is also available for swing landing doors.
