What are the risks of home elevators? Home elevators should pay attention to these risks?
Posted by Admin | 18 Aug
Home elevators have become popular in our lives. Many families use home elevators. These products can bring great convenience to our lives, but they also bring certain risks. What are the risks of home elevators?
Home elevators do not belong to the scope of special equipment supervision and do not require inspection by special equipment inspection agencies. At the same time, the manufacturing standards for home elevators are also recommended standards. Coupled with the individual needs of users, home elevators produced by manufacturers bring certain safety risks to the use and maintenance of elevators.
1. Safety risks caused by hoistway layout
The installation position of the home elevator is determined according to the different needs of each family, especially for houses without reserved wells, the safety of the installation position is more difficult to guarantee. Some home elevators may have accessible space under the hoistway and do not have solid piers, which brings certain safety risks to people passing under the hoistway.
2. Safety risks caused by small shaft space
The narrow shaft space brings great inconvenience to the installation and maintenance of home elevators. The well pits of home elevators are often shallow and the height of the top floor is not enough. If the manufacturer does not install the mechanical locking device and the lower mechanical locking device according to the national recommended standards, it will bring safety risks to the elevator maintenance personnel.
3. Safety risks caused by no well
In order to save cost and floor space, some home elevators are not equipped with shafts, as shown in Figure 3. Although the elevator has the function of automatically stopping when encountering an obstacle, it will still cause certain damage to the obstacle due to inertial action. Especially when the user passes above or below the running elevator, collision and tripping will inevitably occur, and its reliability needs to be verified, which brings great safety risks.
4. There is no safety risk caused by doors and walls
Doorless home elevators mainly appear in low-cost home elevators. As an important safety measure to protect passengers in the car, the car doors and car walls prevent shearing risks caused by relative movement between the car and the hoistway walls. Undoubtedly, elevators without car doors bring huge safety hazards to passengers, but I think that improving users' safety awareness can greatly reduce safety hazards. For example, the user should stand quietly in the middle until the elevator stops.
5. Security risks caused by non-maintenance
Although domestic elevators do not belong to the scope of special equipment supervision, they still need to be regularly maintained by professional maintenance units. Some users may not entrust the corresponding maintenance unit to carry out daily inspection and regular maintenance without knowing it. However, the maintenance of domestic elevators is very professional, and users cannot find their potential fault points in time. They usually don't break or repair, minor injuries and serious illnesses. In the long run, it will pose a security risk to users.
