Here at Elevators Ltd, we have begun to notice that a vast majority of the educational blogs about our industry on the internet tend to focus on the internal components of a lift, such as the motor and the counterweight. With this said, passengers would not be able to use an elevator without a fully-functioning set of doors. Read on as we go over everything there is to know about the way that elevator doors work….
Many people tend not to notice that an elevator is often fitted with two separate doors: one for the cab itself and one that separates the floor from the shaft. This is typically incorporated for safety reasons in order to ensure that passengers are protected from the dangers of an open elevator shaft, however it also has aesthetical and psychological origins as having a separate door on the inside of a cab ensures that the décor is not affected during a journey and also prevents passengers from viewing the walls of the elevator shaft, reducing the likelihood of agoraphobia.
In layman’s terms, an elevator door is attached to a long metal. When the motor is activated, a wheel begins to turn which moves this metal arm from side to side on a rail-like system and allows the doors of a cab to open and close smoothly. This system is found on both sides of a cab because elevator doors open by splitting from the centre which means that each side must be programmed to move in unison.
With this said, there is a common misconception that elevator doors are fitted with an automatic sensor and that the presence of a person will trigger them to open. Whilst it is true that safety is taken into consideration during the manufacture of a lift, the majority of modern elevators use a computer that tells the doors to open and close which means that pushing one’s hand in the doors may lead an avoidable injury.
It is vital that property owners pay close attention to the way that their elevator operates as catching a malfunction sooner rather than later can save a lot of time and money. With this said, the doors are often neglected when it comes to lift maintenance because property owners often carry out brief inspections and place a lot of focus on the general wellbeing of a cab.
