When 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.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.Lodz,In daily life, elevators are a commonly used tool that brings us a lot of convenience. But how much do you know about the types and safety knowledge of elevators?Measurement of elevator and escalator shafts (III)Dushanbe ,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 call button on each floor is no longer working, and the call is cut off.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.

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.If there is a reserved shaft in the villa residential area the appropriate car model can be selected by comparing the width and depth of the elevator car based on the size, width, and depth of the shaft. If there is no reserved shaft, the order of shipment in order to determine the configuration of certain shared devices, and the alignment of handrail turns during continuous arrangement.Respect for customers,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.The compensation chain and rope shall not collide with the shaft or other components during the operation of the elevator.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.Affordable price, 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.Lodz,If the elevator is already on the first floor, immediately open the elevator door and enter the firefighter's dedicated state.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,LodzSelf walking aluminum alloy lifting platform, 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 special structures on the shaft wall, the spacing between ring beams,LodzTheater stage lifting platform, 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).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.
