HenanTwo roll hydraulic fully automatic plate rolling machine,HenanElevating stage,

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.The speed limiter tensioning device and the steel belt tensioning device should be equipped with a safety switch.Henan,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.There is a dedicated fire telephone in the fire elevator car.Doncaster,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 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.There is a dedicated fire telephone in the fire elevator car.

Restore the command button function in the cabin for firefighters to operate.Will the elevator quickly fall during a power outage& mdash;& mdash; Some movies and TV dramas often mislead the public into thinking that if the elevator loses its power, 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.Direct material,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.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 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.

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.Application process,The call button on each floor is no longer working, and the call is cut off.Home elevators are different from public spaces, such as professional home elevators, villa home elevators, home elevator manufacturers,HenanVilla Home Elevator, lack of dedicated hoistways and other special products. Old brands have advantages in price and guaranteed quality. Considering the limited installation space, and small lifting height, and the existence of computer rooms is not necessary. Long term promotion of home elevator manufacturers, 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.Henan,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.Measurement of elevator and escalator shafts (III)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.
