Maintenance of elevator hall doors and car doors. Elevator malfunctions usually occur on the elevator hall and car doors, 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, as the frequency of opening and closing the door in the elevator is high, 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.Measure the length,KircheVertical obstacle free lifting platform, width, and depth of the pit (if any), and observe whether there are grooves and embedded parts at the support beam.Kirche,Elevator Tip : Why elevators can trap people? Every elevator door on each floor has a safety switch, 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 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.Batgrām,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, 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.The speed limiter tensioning device and the steel belt tensioning device should be equipped with a safety switch.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, 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.Household elevators must be regularly maintained to confirm their safety and whether they can continue to operate while also repairing any faults and hidden dangers found.Please note that there should be a space of over mm left on both sides of the escalator, and when arranged in parallel, there is no restriction between the two escalators.Create brilliance,During the use of elevators, some elevator users seek temporary workers or unqualified companies for elevator maintenance in order to reduce costs and save funds. Once safety issues arise, even the responsible unit cannot be found. If the maintenance is carried out by elevator manufacturers or qualified professional companies, on the one hand, the maintenance technology and quality are guaranteed, and on the other hand, if any problems occur, someone is also responsible.The beam edge distance is too small: The method of shortening the lower platform is to shorten the total length of the escalator,KircheRear flip hydraulic plate flipper, but note that the range of shortening is very limited, generally not exceeding mm. Generally, the platform cannot be shortened because it contains equipment such as cabinets and motors. Change the angle of the escalator from degrees to degreesThe treatment of general civil engineering problems on escalator sites: the beam edge distance is too large: in this case, or both platforms can be extended simultaneously. The total extension of the upper and lower platforms should generally not exceed mm. When lengthening the platform, 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, support needs to be added in the middle of the escalator truss. In addition, changing the angle of the escalator from degrees to degrees can also make the beam edge distance longer.

When the normal power supply is cut off the lighting inside the non fire elevator has no power, while there is still lighting inside the fire elevator.Price,Tower style residential buildings above; Residential units and corridors with twelve or more floors; Other Class II public buildings with a building height exceeding meters; High rise buildings with elevators exceeding 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 square meters; The front room area of public buildings and high-rise factory (warehouse) buildings is greater than 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 square meters, and the area of the shared front room in public buildings and high-rise factory (warehouse) buildings is greater than square meters.Elevators are used to transport firefighters, 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 requirementsThe front room of the fire elevator is equipped with Class B fireproof doors or fireproof rolling shutters with stopping function.Kirche, try to obtain relevant data outside the shaft, such as the size of the machine room,KircheSecond floor household elevator, 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, 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).Measure the length, width, and depth of the pit (if any), and observe whether there are grooves and embedded parts at the support beam.
