Hanshan5-storyWhen accidentally trapped in an elevator, one should remain calm, press the alarm bell inside the elevator, and call the elevator emergency rescue phone or community property phone for help. Do not open doors or mess with buttons, and patiently wait for rescue.
Overloaded elevators do not operate: The load of elevators is limited, and if they are overweight, they will alarm and generally cannot be started. Most passengers can also voluntarily exit.
Hanshan.For escalators that require intermediate support, it is necessary to determine whether the site has the conditions for adding support, the height and load size of the equipment and support platform, and other parameters.
In daily life, elevators are a commonly used tool that brings us a lot of convenience. But how much do you know about the types and safety knowledge of elevators?
.Slide elevators are installed inside buildings and are often used parallel to buildings and sidewalks
Passengers wearing long skirts and strapping sandals when riding on the escalator should try to stand slightly in the middle of the escalator to prevent shoes and clothing from being drawn into the escalator and causing danger,HanshanHousehold indoor elevator small, and to prevent skirts or pants from getting stuck.
2. Different types of civil engineering traction elevators, screw elevators, and hydraulic elevators have different requirements for civil engineering. Common traction elevators require a certain amount of hoistway space, which can be made of concrete, steel structure hoistways, and glass curtain walls to create sightseeing elevators; The depth of the pit should be at least 50cm or more; Additionally, there are certain requirements for the height of the top floor.
Elevator Tip 1: Why elevators can trap people? Every elevator door on each floor has a safety switch, which can trigger the elevator to shut down in case of any abnormality. The elevator getting stuck is actually when the system detects an abnormal signal and triggers a protective device like braking to stop.
Dragging Method&ndash& mdash; AC dual speed, Low speed elevators with frequency modulation and speed regulation often use AC dual speed (AC -) It changes the number of poles of the electric motor to achieve speed regulation, allowing the elevator to have a low-speed operation process before the leveling brake, thereby reducing the impact of sudden deceleration during elevator leveling and improving passenger comfort. The advantages are fewer links and low failure probability, while the main disadvantages are poor comfort. The straight elevator starts frequently, and the impact current during startup is too high, brand elevators must have third-party testing, and elevators that have been inspected by professional organizations are safe, reliable, and guaranteed to be used with peace of mind. In addition, when choosing to purchase villa elevators, it is important to understand the safety components and configuration of this elevator. The essential safety equipment in the villa elevator includes a backup power supply and an emergency call outside telephone system to ensure the safety of private users on the elevator.
Encyclopedic knowledge.The elevator stops on the first floor and the door does not move: the fire emergency landing function of the elevator is triggered by smoke or thermal sensors inside the building.
The seat elevator person sits on a chair driven by an electric motor, and the button on the chair handle causes the power drive device at the bottom of the chair to drive the person chair up and down along the guide rail of the staircase railing
2. Different types of civil engineering traction elevators, screw elevators,HanshanFixed lifting stage, and hydraulic elevators have different requirements for civil engineering. Common traction elevators require a certain amount of hoistway space, which can be made of concrete, and glass curtain walls to create sightseeing elevators; The depth of the pit should be at least 50cm or more; Additionally, there are certain requirements for the height of the top floor.
These phenomena are not elevator malfunctions. When the elevator is fully loaded, the elevator car no longer responds to the next station's outbound call.
Lets see.Slide elevators are installed inside buildings and are often used parallel to buildings and sidewalks
The important components of elevators require certain technologies, such as the traction machines of passenger elevators and sightseeing elevators that are permanent magnet synchronous, and the car door machine that is frequency conversion, voltage regulation, and speed regulation, and adopts light curtain protection. Safety components such as safety gear, speed limiter, and buffer must be manufactured.
There are many similar situations in daily life such as forcefully opening the door inside the car, causing the circuit to disconnect and forcing the elevator to stop, resulting in people being trapped. For example,HanshanVilla small household elevator, if the elevator frequently enters and exits during decoration and falls into the crack of the door, the elevator hall door may not be tightly closed, and after several consecutive doors are opened and closed, the elevator will stop. Professional quality assurance for home elevator manufacturers. Discount activities are underway, and new and old customers are welcome to come for consultation
Hanshan.The difference between home elevators and ordinary public elevators is that the focus of home elevators and ordinary public elevators is different, with some indicators significantly reduced. For example, the load capacity of home elevators does not exceed 400kg, which is much lower than that of ordinary public elevators. Home elevators do not need to consider the issue of passenger flow, and the lifting speed is slower, ensuring safety. The lifting speed is generally between 0.3 to 0.4m/s, and running smoothly.
When accidentally trapped in an elevator, one should remain calm press the alarm bell inside the elevator, and call the elevator emergency rescue phone or community property phone for help. Do not open doors or mess with buttons and patiently wait for rescue.
The elevator stops on a certain floor for a long time without moving or responding to external calls: it is possible that the elevator administrator has activated the driver operation function.
