The speed limiter tensioning device and the steel belt tensioning device should be equipped with a safety switch.The call button on each floor is no longer working and the call is cut off.Oldenburg,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.The mechanical components of the elevator's traction machine require oil. There are two scales on the outer cover of the traction machine. Open the oil nozzle to check that the oil should be in the middle of the two scales. If the oil is lower than the lower scale, the elevator will not operate well for a long time,OldenburgSecond floor household elevator, leading to the burning of the elevator traction machine and motor. After the elevator has been running for a long time, the oil should be replaced in a timely manner to keep the traction machine clean and in good condition.Gdynia,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 degreesThe 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.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, after maintenance or urgent repairs are completed, 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,OldenburgSelf propelled aluminum alloy elevator, sturdy and durable, safe and reliable

There is a dedicated fire telephone in the fire elevator car.The gantry elevator is used in the door legs of large gantry cranes to transport workers and maintenance components inside the gantry craneTo 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.Quality management,If the elevator is already on the first floor, immediately open the elevator door and enter the firefighter's dedicated state.There are dedicated operation buttons for firefighters at appropriate positions at the entrance of the first floor elevator. The operation buttons are generally protected by glass sheets and have a red&# quo; mark in place; Dedicated to fire protection; Words such as.Measurement of elevator and escalator shafts (III)

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, and the cabin should be cleaned thoroughly.Excellent quality,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, such as the size of the machine room, 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,OldenburgFamily villas and elevators, 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 gantry elevator is used in the door legs of large gantry cranes to transport workers and maintenance components inside the gantry craneMeasurement of elevator and escalator shafts (III)Oldenburg,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 front room of the fire elevator is equipped with Class B fireproof doors or fireproof rolling shutters with stopping function.Multiple elevator shafts can be connected and an - # I-beam can be fixed at a certain height between each adjacent elevator shaft with the same position as the ring beam. The pit must be equipped with an isolation net that is mm above the ground level.
