HartwanElevatiWill the elevator quickly fall during a power outage& mdash;& mdash; Some movies and TV dramas often mislead the public into thinking that if the elevator loses its power, it will lose control and engage in falling movements.
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 if the elevator frequently enters and exits during decoration and falls into the crack of the door,HartwanStage boom elevator, 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
Hartwan.Tower style residential buildings above; Residential units and corridors with twelve or more floors; Other Class II public buildings with a building height exceeding 32 meters; High rise buildings with elevators exceeding 32 meters in height; The functional fire elevator has a front room. The area of the independent fire elevator front room is: the front room area of the residential building is greater than 5 square meters; The front room area of public buildings and high-rise factory (warehouse) buildings is greater than 6 square meters. When the front room of the fire elevator is shared with the smoke proof staircase, its area is: the area of the shared front room in residential buildings is greater than 6 square meters, and the area of the shared front room in public buildings and high-rise factory (warehouse) buildings is greater than 10 square meters.
The elevator suddenly opens the door and does not move after leveling, but automatically resumes operation after a few minutes: The elevator (escalator) has been running for too long, and the motor overheats. To prevent burning out, the motor cools down and automatically resumes operation.
.Elevator does not close the door or repeatedly opens and closes the door: there are debris blocking the light curtain or door contact plate at the entrance or sill.
When wearing high heels, be careful not to step on the gap between the pedals, 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, 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, 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.
The progressiveness of elevator is mainly reflected in the drive and technology. The frequency modulation voltage regulation speed regulation technology (VVVF) is now the main energy-saving and drive technology. The microcomputer system realizes intelligence for elevators, with low failure rate, high reliability, and strong anti-interference ability in use.

Test results.When passengers are riding on the escalator, they may lose their balance and fall due to leaning against the skirt board on the side of the escalator, which does not move, but their feet move with the steps. Especially when carrying a lot of packages while taking the elevator, it is more likely to fall on the escalator due to the inability to hold the handrail properly. So, we must stand firmly and support it well, they may lose their balance and fall due to leaning against the skirt board on the side of the escalator, which does not move, but their feet move with the steps. Especially when carrying a lot of packages while taking the elevator, it is more likely to fall on the escalator due to the inability to hold the handrail properly. So, when riding on the escalator we must stand firmly and support it well, and do not lean against the skirt board on the side of the escalator.
The elevator suddenly descends to the bottom floor and resumes normal operation: After the elevator is powered off and reconnected,HartwanElevating platform stage, the leveling reference position needs to be re determined.
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
Bidding.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.
Electrical components are roughly divided into screens, electrical switches for each safety circuit, etc. It is the brain of the elevator and the central nervous system of the elevator. The movement, operation, and door opening and closing of the elevator are all controlled by it, so it must be treated as a top priority in daily maintenance work. Do not short circuit the elevator circuit inside the screen during work. When the elevator door system malfunctions, someone shorts the elevator door for convenience in order to find the fault. This is very dangerous, and there are many accidents when shorting the door. Why? If a person opens the hall door and extends their head inward, the elevator happens to run up or down to this point, and the hall door is shorted, the elevator cannot stop, so an accident is highly likely to occur. So in our daily maintenance work, we must not short-circuit the safety circuit. If it is necessary to short-circuit, we must identify which safety component has a problem and which safety component needs to be shorted. Moreover, after maintenance or urgent repairs are completed, we must promptly remove the short-circuit wire. Professional household elevator manufacturer, with a large quantity and excellent quality at a reasonable price. It is fire-resistant waterproof, high-temperature resistant, sturdy and durable, safe and reliable
Slide elevators are installed inside buildings and are often used parallel to buildings and sidewalks
Hartwan.The braking system of the elevator is usually closed, which means it is in the braking state when there is no power, and only when it needs to be turned on, will the power turn on the brakes. So as soon as there was a power outage, the brakes closed and the elevator was braked in mid air. When the elevator descends abnormally,HartwanStage main lifting platform, it is cut off
Elevators are used to transport firefighters, passengers, and fire-fighting equipment in the event of a fire. They are used to transport frozen goods in large cold storage or refrigeration workshops. However, they need to meet the requirements of sealing the door leaves and guide rails at the moving parts. Professional household elevators, villa household elevators household elevator manufacturers, and small household elevators have stable, safe, reliable, and maintenance free performance, and their technical level has reached the domestic level, Meet the advanced level of international similar products and immersion requirements
