Cross signHousehold outdoor elevator on the third floor,

Measure the beam edge distance between the upper and lower support beams. The measurement is to suspend the line from the upper support point to the ground for positioning, and then measure the horizontal distance from the positioning point to the edge of the lower support beam.The treatment of general civil engineering problems on escalator sites: the beam edge distance is too large: in this case,Cross signSelf propelled aluminum alloy elevator, 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.Cross sign,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.Measure the length, width, and depth of the pit (if any), and observe whether there are grooves and embedded parts at the support beam.Jakobsberg,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,Cross signFully automatic hydraulic pressure for plate rolling machine, 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 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 front room of the fire elevator is equipped with indoor fire hydrants.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.

In the event of a fire, 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.Home elevators are different from public spaces, such as professional home elevators, home elevator manufacturers, small home elevators, and other special products. Old brands have advantages in price and guaranteed quality. Considering the limited installation space, lack of dedicated hoistways, and the existence of computer rooms is not necessary. Long term promotion of home elevator manufacturers the design pursues simplicity and miniaturization, old brands, price advantages, and guaranteed quality!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.Sampling inspection,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.b. When the old elevator cannot start: due to the inability to enter the shaft, limited data can only be obtained from outside the shaft to determine whether it is non-standard (if there is a high platform in the machine room, the plane size of the shaft can be measured in the machine room, but it is not accurate enough) for elevator quotation negotiation reference. In this case, the signing of the contract should state that the shaft rectification and costs are the responsibility of the user. For uncertain shaft structures and dimensions, users should be reminded to provide them to the elevator after the old elevator or notify the elevator to take measurements before the new elevator is put into operation.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.

Measure the length, width, and depth of the pit (if any), and observe whether there are grooves and embedded parts at the support beam.index,The front room of the fire elevator is equipped with Class B fireproof doors or fireproof rolling shutters with stopping function.In daily life, the elevator components in operation are inspected, refueled, dust is removed, and safety devices are debugged. Including non-destructive testing and maintenance of elevator traction steel wire ropes.Cross sign,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 door closing button has no self maintenance function. During the designated maintenance period, the elevator components in operation are inspected, refueled, dust is removed, and safety devices are debugged. Including non-destructive testing and maintenance of elevator traction steel wire ropes.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.
