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
Machine room power supply: The power supply should be three-phase 380V, 50HZ, and the lighting power supply should be single-phase 220V, 50HZ. The incoming line should be connected to the vicinity of the machine room entrance and equipped with an incoming socket. Specializing in product and renewable resource business, including: home elevator manufacturers

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.
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.

how much.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 shaft for updating the old elevator: The measurement of the shaft for the old elevator is the same as the shaft that has just been constructed. When the old elevator is not yet in use, such as the size of the machine room, floor height, and net size of the door opening. There are two situations when the old elevator is not yet in use: a. When the old elevator can start: in this case, the elevator technician must cooperate in measuring the shaft! And be sure to pay attention to safety! The elevator technician opens the hall door on the first floor and initiates maintenance operations to drive the car above the second floor. The measurement personnel open the floor door on the first floor to measure the pit data, paying attention to recording the pit size and the wall structure of the first floor, such as whether the hall door is centered,NejackRear flip hydraulic plate flipper, whether there are brackets, the spacing between ring beams and the position of embedded parts. Then, the measuring personnel and elevator technicians take the elevator to the top floor. After measuring the machine room, the measuring personnel, with the cooperation of the technicians, go up to the car roof and start the elevator at a maintenance speed. When the car roof is slightly lower than the sill of the second floor hall door, the parking lot stops. During this process, the measuring personnel observe and measure the full travel of the shaft from the top floor, mainly the height of the floor, and special attention should be paid to moving parts such as counterweights and wire ropes).

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, and depth of the shaft. If there is no reserved shaft
