The speed limiter tensioning device and the steel belt tensioning device should be equipped with a safety switch.Cleaning and cleaning of elevator car guide shoes. As is well known, the guide shoe runs on the guide rail, and there is an oil cup on the guide shoe. To ensure that the elevator does not make any noise during operation, it is necessary to regularly refuel the oil cup and clean the guide shoe, and the cabin should be cleaned thoroughly.Horn,As elevator people, let's talk about elevator and elevator safety knowledge: The elevators we currently use include box type passenger elevators, escalators, and dedicated cargo elevators. Dedicated cargo elevators are installed due to special needs, and we don't use many of them. Now, let's take a look at the safety knowledge of box type passenger elevators and escalators: When we take escalators, Be sure to follow the safety instructions when riding on the elevator. Do not crowd or play around, hold onto the elevator firmly, fasten your shoelaces, and avoid getting them caught up.Electrical safety. Faulty elevators have multiple safety devices, but there are also many places where problems can occur. Some people have been caught due to abnormal door opening and closing, while others have encountered situations where elevator buttons malfunction and the display screen is black, 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, 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 uneasyAz Zulfi,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, 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 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).Brick concrete structure elevator shaft: For unfinished brick structure shafts, users can be required to make a circle of beams at a certain height, arranged on three sides, and disconnected on one side of the elevator entrance. The distance between the center heights of the beams depends on the product model, and should not exceed mm. The beam height should be mm, and the thickness should be the same as the wall. The lower ring beam is -mm away from the bottom of the pit, and the higher ring beam is -mm away from the lower surface of the shaft roof. The completed framework with a solid brick structure shaft can be equipped with steel plywood at the position of the fixed guide rail support frame. The position and size of the plywood are provided by the elevator, and the user is responsible for providing materials and construction. If the shaft structure is made of hollow bricks without ring beams, steel beams can be considered to be added between the frames for rectification.Cleaning and cleaning of elevator car guide shoes. As is well known,HornAccessible lifting platform, the guide shoe runs on the guide rail, and there is an oil cup on the guide shoe. To ensure that the elevator does not make any noise during operation,HornHome villa sightseeing elevator, it is necessary to regularly refuel the oil cup and clean the guide shoe, and the cabin should be cleaned thoroughly.

The front room of the fire elevator is equipped with Class B fireproof doors or fireproof rolling shutters with stopping function.. 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 cm or more; Additionally, there are certain requirements for the height of the top floor.For escalators that require intermediate support, it is necessary to determine whether the site has the conditions for adding support, as well as the range of support that can be added, the height and load size of the equipment and support platform,Measurement of elevator and escalator shafts (III)If the elevator is in a downward direction, immediately close the door and return to the first floor station, and automatically open the elevator door.The household must make two steel splints above the entrance. The position and size of the clamp plate are determined based on the selected door machine model.

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, 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,HornStage lifting platform, high-temperature resistant sturdy and durable, its area is: the area of the shared front room in residential buildings is greater than square meters, and the area of the shared front room in public buildings and high-rise factory (warehouse) buildings is greater than square meters.Horn,Measure the length, width, and depth of the pit (if any), and observe whether there are grooves and embedded parts at the support beam.The basic content of escalator shaft measurement is to measure the lifting height. The same as measuring the height of a straight ladder, strictly speaking, the lifting height of a ladder is the vertical distance between the finished ground at the upper and lower support beams. When using the suspension line method to measure, attention should be paid to whether there is a drop between the positioning point of the line drop and the decoration surface of the lower support beam of the ladder.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, 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.
