Elevators are crucial facilities and equipment in various property supporting constructions, playing an increasingly important role in the lives of homeowners and residents. In recent years, with the frequent use of elevators and the increasing number of management problems, elevator accidents have occurred repeatedly, which has sounded the alarm for elevator manufacturers, maintenance personnel, and daily elevator managers. So, what aspects should we pay attention to and prevent elevator accidents from happening? Singlin Elevator takes everyone to deeply analyze the elevator industry!

Where are the safety hazards hidden in elevators?

Elevators, as an indispensable means of transportation in high-rise buildings, are receiving increasing attention for their equipment stability and safety. For high-rise buildings, the configuration and selection of elevators directly affect whether the entire building structure is properly utilized. What aspects should be considered when selecting elevators for high-rise buildings to meet their actual needs?

One is speed. High rise buildings often reach heights of 200 meters, 300 meters or more, and choosing high-speed elevators is beneficial for quickly transporting personnel during certain peak hours. For example, a direct sightseeing elevator with a speed of 8 meters per second can quickly transport passengers to the 72nd floor (actually the 59th floor) in just over 40 seconds. Even if there are many visitors, it will not delay passengers' time. For example, a fire elevator with a speed of 7 meters per second can ensure that firefighters can reach any floor from the negative 4th floor within 2 minutes, providing very favorable conditions for firefighting work. Passengers usually take the elevator from the first floor to the floor they are on, and it is more appropriate to control it within 5 minutes.

The second is the size and quantity of elevators. The size of the elevator car and the number of elevators need to be reasonably matched. Choosing elevators with large cars (i.e. passenger elevators with high load capacity) can reduce the number of elevators and save building area and elevator costs, but it increases the average interval time and makes maintenance inconvenient; Choosing elevators with small cars but a large number of them, although occupying a larger building area and having higher elevator costs, greatly improves the conveying capacity, shortens the average interval time, and ensures that elevator maintenance does not affect the normal use of passengers. It is recommended to choose elevators with a load capacity of 1 ton, and it is better to have more elevators. Generally, office buildings require between 0.3-0.5 elevators per 100 people, and it is better to choose 0.5 elevators.

Thirdly, elevators with different purposes require different requirements. The requirements for passenger elevators are speed and quantity, but for freight elevators, we have found that their frequency of use far exceeds that of passenger elevators. They are not only used by property management personnel for cleaning, inspection, and garbage collection during the day, but also for moving or transporting materials at night. The quality and management of freight elevators are also crucial. When choosing a freight elevator, it is important to choose a top tier brand in the market that has a good reputation, durability, and good quality.

The fourth is after-sales service. Building construction may only take one or two years, but the use of buildings takes decades, and elevators also need to be used for a long time. Elevator maintenance work has been closely related to property management since the delivery of buildings. Having an elevator maintenance unit that satisfies homeowners with its services will bring great benefits to property management work.

How to prevent elevator safety hazards?

Elevator malfunction refers to the phenomenon where the mechanical components or electrical control system components of an elevator malfunction, causing the elevator to malfunction or seriously affecting passenger comfort, and even causing personal injury or equipment accidents. So what common elevator malfunctions should be prevented in daily use of residential elevators (vertical elevators)?

The main causes of malfunctions in residential elevators during daily use are:

1. Improper equipment management by elevator users (such as community property management)

2. Improper use of passenger elevator

3. Inadequate maintenance by the maintenance unit

4. Elevator components aging

5. External reasons (such as power supply issues: unstable power supply voltage or power outage in residential areas)

Additionally, there are special reasons to be aware of:

Malfunctions caused by the elevator door system: such as elevator malfunctions caused by obstructed opening and closing of doors due to household waste and decoration waste; Rough handling caused door deformation and elevator malfunction; Blocking the door closing time for too long causes the elevator protection to close the door lock flexibly.

Malfunction caused by inadequate maintenance: Some safety protection switches of the elevator are activated, such as the misoperation of the speed limiter switch; Speed limiter tensioner switch action; Buffer electrical switch action; Aging electrical components have not been detected.

Malfunctions caused by aging of elevator components: Elevator frequency converter protection, aging of electrical components (contactors, relays, drive components, control boards) causing elevator malfunctions.
