The speed limiter tensioning device and the steel belt tensioning device should be equipped with a safety switch.To implement the arrangement of escalators and provide feedback, in order to determine the configuration of certain shared devices, the order of shipment, and the alignment of handrail turns during continuous arrangement.Bitom,Elevator does not close the door or repeatedly opens and closes the door: there are debris blocking the light curtain or door contact plate at the entrance or sill.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.San Gwann,There is a dedicated fire telephone in the fire elevator car.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.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.

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, 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.The elevator suddenly opens the door and does not move after leveling, but automatically resumes operation after a few minutes: The elevator (escalator) has been running for too long, and the motor overheats. To prevent burning out, the motor cools down and automatically resumes operation.The safety monitoring machine room environment screen cabinet main power switch traction wheel speed limiter shaft and pit guide rail layer door and car counterweight should be reliably fixed with pressure plates to prevent loosening.offer,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 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.In the event of a fire, when instructed by the fire center or the dedicated operation button of the first floor firefighter to enter the firefighting state, return to the first floor station, and automatically open the elevator door if it is in the upward direction.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.

If the elevator is already on the first floor, immediately open the elevator door and enter the firefighter's dedicated state.High quality brand,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, 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, 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 reliableThe 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.The front room of the fire elevator is equipped with Class B fireproof doors or fireproof rolling shutters with stopping function.Bitom,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, 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.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,BitomMobile reclaimer, 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 special structures on the shaft wall, the spacing between ring beams,BitomFixed lifting stage, 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,BitomSemi electric high-altitude reclaimer, 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).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.
