　　What is the load-bearing capacity of home elevators? What are the safety protection systems?

　　Each home elevator has its load-bearing specifications. When we are riding, we will encounter the alarm sound when the elevator is overloaded. Similarly, if the elevator is overweight, its safety warning mechanism will not work, and it is easy to malfunction at this time. So when we decorate, we should try not to choose too heavy materials, such as some marble, and choose some lighter materials.

　　For elevator consumers and secondary decoration customers, home elevator car decoration is particularly important. In order to make it easier and more accurate for elevator manufacturers to calculate the parameters of the elevator factory, it is necessary to know the weight of the elevator car decoration so that when the elevator manufacturer adds the weight of the elevator decoration to the weight of the car.

　　If the elevator is a secondary decoration, the weight of the elevator decoration should be considered even more. Before choosing the elevator car decoration style, the customer needs to inform the weight of this car decoration in advance so that the customer can stop checking the elevator configuration parameters. Because the weight of the elevator car decoration is too heavy, the image balance coefficient will appear. Once the balance coefficient is broken, the factory parameters of the elevator will change, and the resistance and braking load of the elevator will also increase. This will not only accelerate the loss of equipment and shorten the service life, but also bury safety hazards.

　　Attention should also be paid to the weight of the home elevator door decoration. Elevator doors are divided into steel doors, stainless steel doors, glass doors, etc. If the elevator car door is a steel plate car door or a stainless steel car door, you only need to configure an ordinary door machine when configuring the door machine. If the elevator car door is a glass car door, then under the same specifications, the weight of the glass car door is twice that of the steel car door, so we must pay attention to the selection of the door machine and need to configure a door machine that can pull the glass car door.

　　For the safety of home elevators, it has always been a major concern for many high-rise residents, and no one pays attention. Although there are many safety protection measures, various safety accidents still occur in recent years. The following is a brief introduction to the main safety protection systems of home elevators.

　　1. Prevent over-running

　　This is mainly to prevent the elevator from running beyond the top or bottom terminal due to control failure, so a protective device is set to prevent serious consequences and structural damage.

　　II. Overspeed and rope-breaking protection for home elevators

　　The overspeed rope-breaking protection device is a safety clamp-speed limiter system. The safety clamp is a mechanical device that prevents the downward movement of the car. All elevator cars suspended by wire ropes or chains should be equipped with safety clamps. Therefore, when someone can enter the pit space, the counterweight can also be equipped with a safety clamp. The safety clamp is generally installed on the threshold of the frame and acts on the guide rail in pairs.

　　III. Preventing people from shearing and falling

　　Anti-fall and shearing protection are mainly undertaken by the door, door lock and electrical safety contacts of the door.

　　IV. Buffer device for home elevators

　　When the car or counterweight squats due to elevator control failure, insufficient traction or brake failure, the buffer will absorb the kinetic energy of the car or counterweight and provide protection to ensure the safety of personnel and elevator structure.

　　V. When elevator personnel are trapped in the car, the situation should be promptly reported to the management personnel through the alarm or communication device, and the personnel should be safely rescued from the car through the rescue device.

　　VI. Stop switch and maintenance operation device

　　If the elevator needs maintenance, it can be stopped, and it should not be started suddenly to avoid hurting the maintenance personnel.

　　VII. Firefighting function

　　Once a fire occurs, the shaft is often a channel for smoke and flames to spread. For the safety of passengers, all home elevators should be able to return directly to the evacuation staircase platform in the event of a fire, that is, they have the function of automatically returning to the base station in the event of a fire.
