The front room of the fire elevator is equipped with Class B fireproof doors or fireproof rolling shutters with stopping function.The effective support width of the upper and lower support beams should be greater than the width of the escalator truss, and there should be embedded steel plates.Oke,Mine elevators are used for transporting personnel and goods in mines. Special elevators are designed for special environmental conditions, anti-corrosion, and heat-resistant elevatorsElectrical safety. Faulty elevators have multiple safety devices, making it difficult to see the floor clearly. Some have experienced the danger of falling straight several floors. Although there may not have been any personal injury while others have encountered situations where elevator buttons malfunction and the display screen is black, taking the elevator is not about finding or acting in a movie. The real life is disturbed by the frequent elevator accidents, which make my heart feel uneasySonderborg,b. When the old elevator cannot start: due to the inability to enter the shaft, limited data can only be obtained from outside the shaft to determine whether it is non-standard (if there is a high platform in the machine room, the plane size of the shaft can be measured in the machine room,OkeHousehold small elevator prices, but it is not accurate enough) for elevator quotation negotiation reference. In this case, the signing of the contract should state that the shaft rectification and costs are the responsibility of the user. For uncertain shaft structures and dimensions, users should be reminded to provide them to the elevator after the old elevator or notify the elevator to take measurements before the new elevator is put into operation.Machine room power supply: The power supply should be three-phase V, HZ, and the lighting power supply should be single-phase V, HZ. 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 manufacturersThe call button on each floor is no longer working, and the call is cut off.

The mechanical components of the elevator's traction machine require oil. There are two scales on the outer cover of the traction machine. Open the oil nozzle to check that the oil should be in the middle of the two scales. If the oil is lower than the lower scale, the elevator will not operate well for a long time, leading to the burning of the elevator traction machine and motor. After the elevator has been running for a long time the oil should be replaced in a timely manner to keep the traction machine clean and in good condition.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 kg, 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 . to .m/s, and running smoothly.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, try to obtain relevant data outside the shaft, such as the size of the machine room,OkeAutomatic high-altitude reclaimer, 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, whether there are brackets whether there are special structures on the shaft wall, 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,OkeElectric high-altitude reclaimer, the measuring personnel observe and measure the full travel of the shaft from the top floor mainly the height of the floor, while recording the measurement (safety must be paid attention to, and special attention should be paid to moving parts such as counterweights and wire ropes).average method,The effective support width of the upper and lower support beams should be greater than the width of the escalator truss, and there should be embedded steel plates.The front room of the fire elevator is equipped with indoor fire hydrants.Electrical components are roughly divided into screens, electrical switches for each safety circuit, 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

　　“& rdquo; Elevator shaft: The design conditions are provided by the user to the architectural design department. The architectural design department analyzes whether the on-site pit depth, top floor height, reaction force, etc. can meet the installation requirements of the elevator, as well as which building structures are needed (such as smashing stairs or floors), and develops a renovation construction plan. If it is indeed necessary to change the elevator structure due to civil engineering conditions (such as car size, door opening width, etc.), then consider the non-standard design of the elevator.Meticulous workmanship,There is a dedicated fire telephone in the fire elevator car.Aircraft weighing tens or hundreds of tons in the elevator hangar are vertically lifted onto the airport runwayMeasure the length, width, and depth of the pit (if any), and observe whether there are grooves and embedded parts at the support beam.OkeMultiple elevator shafts can be connected and an - # I-beam can be fixed at a certain height between each adjacent elevator shaft, with the same position as the ring beam. The pit must be equipped with an isolation net that is mm above the ground level.The speed limiter tensioning device and the steel belt tensioning device should be equipped with a safety switch.The requirement for the shaft is that it should not be plastered, which is beneficial for reducing noise, but there should be no protruding foreign objects.
