YuhuaElevatingThe 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 elevator suddenly descends to the bottom floor and resumes normal operation: After the elevator is powered off and reconnected, the leveling reference position needs to be re determined.
Yuhua.Maintenance of elevator hall doors and car doors. Elevator malfunctions usually occur on the elevator hall and car doors, so attention should be paid to the maintenance of the hall and car doors. One is to refuel the fuel on the upper sill of the door and keep it in good condition, so that the elevator will not make unpleasant noises during operation and the opening of the door. Pay attention to the inspection of the safety contact plate or light curtain type contact plate switch wire of the elevator, which can cause damage to the switch wire. This requires maintenance personnel to inspect it every time they work, and replace it in advance to avoid users having doubts about the quality of the elevator product due to door issues.
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.
.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, 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
Household elevators have gradually become an essential vertical transportation tool for modern single family, duplex, multi story,Yuhua5-story household elevator small,YuhuaElevating stage, villa and other residential buildings, practical and convenient, and even a beautiful scenery in the home.
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 main parameters that determine the conveying capacity are escalators: quantity, clear width of steps, inclination angle, elevator: rated load, rated speed, large lifting height, quantity,YuhuaSemi electric high-altitude reclaimer, number of floors and stations.
If there is a reserved shaft in the villa residential area, the appropriate car model can be selected by comparing the width and depth of the elevator car based on the size, width, which means it is in the braking state when there is no power you can first choose the model of the elevator and create a new shaft based on the required reserved size space for different models.
Bidding.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.
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 braking system of the elevator is usually closed, 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, it is cut off
The elevator suddenly descends to the bottom floor and resumes normal operation: After the elevator is powered off and reconnected, the leveling reference position needs to be re determined.
Quality Assurance.Household elevators have gradually become an essential vertical transportation tool for modern single family, duplex, multi story, villa and other residential buildings, practical and convenient, and even a beautiful scenery in the home.
The treatment of general civil engineering problems on escalator sites: the beam edge distance is too large: in this case, the length of the upper and lower platforms of the escalator can be increased to meet the actual dimensions of civil engineering. One platform can be extended on one side, attention should be paid to the length of the pit or the opening of the floor slab, which should also be lengthened at the same time. After the escalator is extended, the force on the upper and lower support points will also increase. If the edge distance of the beam increases too long, changing the angle of the escalator from 35 degrees to 30 degrees can also make the beam edge distance longer.
When wearing high heels, be careful not to step on the gap between the pedals, as not wearing shoes is more likely to be pinched by the toothed plate.
Yuhua.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.
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, 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.
Slide elevators are installed inside buildings and are often used parallel to buildings and sidewalks
