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 and other parameters.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.Tappolka,The 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 effective support width of the upper and lower support beams should be greater than the width of the escalator truss,TappolkaHousehold duplex small elevator, and there should be embedded steel plates.Ozgon,The call button on each floor is no longer working and the call is cut off.There is a dedicated fire telephone in the fire elevator car.Measure the length, width, and depth of the pit (if any), and observe whether there are grooves and embedded parts at the support beam.
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 gantry elevator is used in the door legs of large gantry cranes to transport workers and maintenance components inside the gantry craneThe 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, changing the angle of the escalator from degrees to degrees can also make the beam edge distance longer.How many?,The call button on each floor is no longer working, and the call is cut off.The compensation chain and rope shall not collide with the shaft or other components during the operation of the elevator.If the elevator is already on the first floor,TappolkaRear flip hydraulic flipper, immediately open the elevator door and enter the firefighter's dedicated state.
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.Quality recommendation,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, the measuring personnel and elevator technicians take the elevator to the top floor. After measuring the machine room, 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).When encountering abnormal elevator operation, you can call the repair hotline to consult with the maintenance personnel or inform the service center to handle it. Do not take unauthorized measures to avoid causing greater harm to the elevator or even causing casualties.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, and other parameters.Tappolka,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.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.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.
