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.Measure the length, width, and depth of the pit (if any),The elevator stops on the first floor and the door does not move: the fire emergency landing function of the elevator is triggered by smoke or thermal sensors inside the building.Measure the length, width, and depth of the pit (if any),There is a dedicated fire telephone in the fire elevator car.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, 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 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, 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,MaastrichtRear flip hydraulic flipper, 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).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.

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.In daily life, when instructed by the fire center or the dedicated operation button of the first floor firefighter to enter the firefighting state, the elevator should immediately stop on the floor without opening the door, return to the first floor station, and automatically open the elevator door if it is in the upward direction.Installation materials,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.Cleaning and cleaning of elevator car guide shoes. As is well known,MaastrichtSmall stage elevator, 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.The beam edge distance is too small: The method of shortening the lower platform is to shorten the total length of the escalator, 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 degrees

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.Latest quotation,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, the elevator should immediately stop on the floor without opening the door, return to the first floor station, and automatically open the elevator door if it is in the upward direction.Aircraft weighing tens or hundreds of tons in the elevator hangar are vertically lifted onto the airport runwayThe 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, 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.Maastricht,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.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, 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,MaastrichtSemi-automatic high-altitude reclaimer, 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.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.
