“& rdquo; Elevator shaft: The design conditions are provided by the user to the architectural design department. The architectural design department analyzes whether the on-site pit depth, top floor height, reaction force, etc. can meet the installation requirements of the elevator, as well as which building structures are needed (such as smashing stairs or floors), and develops a renovation construction plan. If it is indeed necessary to change the elevator structure due to civil engineering conditions (such as car size, door opening width, etc.), then consider the non-standard design of the elevator.The call button on each floor is no longer working, and the call is cut off.Pwotsk,Slide elevators are installed inside buildings and are often used parallel to buildings and sidewalksThe 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.Kunduz,The door closing button has no self maintenance function. During the designated maintenance period, the elevator components in operation are inspected, refueled, and safety devices are debugged. Including non-destructive testing and maintenance of elevator traction steel wire ropes.When the normal power supply is cut off, while there is still lighting inside the fire elevator.Measurement of elevator and escalator shafts (III)

Machine room power supply: The power supply should be three-phase V,PwotskPrice of hydraulic flipper, HZ, and the lighting power supply should be single-phase V, HZ. The incoming line should be connected to the vicinity of the machine room entrance and equipped with an incoming socket. Specializing in product and renewable resource business, including: home elevator manufacturersThe braking system of the elevator is usually closed, which means it is in the braking state when there is no power, and only when it needs to be turned on, will the power turn on the brakes. So as soon as there was a power outage, the brakes closed and the elevator was braked in mid air. When the elevator descends abnormally, cut off the power and the elevatorIn 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.query,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 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, 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 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.

The beam edge distance is too small: The method of shortening the lower platform is to shorten the total length of the escalator,PwotskAluminum alloy mast type lifting platform,PwotskElevating platform stage, 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 degreesHigh quality brand,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.Slide elevators are installed inside buildings and are often used parallel to buildings and sidewalksRestore the command button function in the cabin for firefighters to operate.Pwotsk,The front room of the fire elevator is equipped with Class B fireproof doors or fireproof rolling shutters with stopping function.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.The compensation chain and rope shall not collide with the shaft or other components during the operation of the elevator.
