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 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

The treatment of general civil engineering problems on escalator sites: the beam edge distance is too large: in this case, 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,Mason AlfordVilla small household elevator, 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.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.Mason Alford,The elevator suddenly opens the door and does not move after leveling, and the motor overheats. To prevent burning out, the motor cools down and automatically resumes operation.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 degreesLuwero,Measurement of elevator shafts in new construction projects under different on-site conditions: When the building design is not yet completed, the operator only needs to provide the user with the standard elevator layout of the required elevator specifications, and the user entrusts the design department to design the elevator shaft. When the architectural design has been completed, and the site has not yet been constructed, is under construction, or has been completed, it must be determined based on the current construction or measured dimensions. If the original civil design of the shaft needs to be modified, the user should entrust the architectural design department to make the shaft design modification based on the layout provided by the elevator.For escalators that require intermediate support, it is necessary to determine whether the site has the conditions for adding support, as well as the range of support that can be added,Mason AlfordFixed stage elevator, the height and load size of the equipment and support platform, and other parameters.Restore the command button function in the cabin for firefighters to operate.

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.The 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 elevatorWhen 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.how much,Measure the length, width, and depth of the pit (if any), and observe whether there are grooves and embedded parts at the support beam.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)

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.Standard requirements,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.When encountering abnormal elevator operation, you can call the repair hotline to consult with the maintenance personnel or inform the service center to handle it. Do not take unauthorized measures to avoid causing greater harm to the elevator or even causing casualties.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.Mason Alford,In the event of a fire, the elevator should immediately stop on the floor without opening the door, and automatically open the elevator door if it is in the upward direction.The requirement for the shaft is that it should not be plastered,Mason AlfordMobile hydraulic turnover machine, which is beneficial for reducing noise, but there should be no protruding foreign objects.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.
