Machine room power supply: The power supply should be three-phase V, HZ, and the lighting power supply should be single-phase V, HZ. The incoming line should be connected to the vicinity of the machine room entrance and equipped with an incoming socket. Specializing in product and renewable resource business, including: home elevator manufacturersRestore the command button function in the cabin for firefighters to operate.Sesena ,The difference between home elevators and ordinary public elevators is that the focus of home elevators and ordinary public elevators is different,Sesena Aluminum alloy movable lifting platform, with some indicators significantly reduced. For example, the load capacity of home elevators does not exceed kg, which is much lower than that of ordinary public elevators. Home elevators do not need to consider the issue of passenger flow and the lifting speed is slower, and running smoothly.Maintenance of elevator hall doors and car doors. Elevator malfunctions usually occur on the elevator hall and car doors ensuring safety. The lifting speed is generally between . to .m/s, so attention should be paid to the maintenance of the hall and car doors. One is to refuel the fuel on the upper sill of the door and keep it in good condition, so that the elevator will not make unpleasant noises during operation and the opening of the door. Pay attention to the inspection of the safety contact plate or light curtain type contact plate switch wire of the elevator, as the frequency of opening and closing the door in the elevator is high, which can cause damage to the switch wire. This requires maintenance personnel to inspect it every time they work, and replace it in advance to avoid users having doubts about the quality of the elevator product due to door issues.East London,If the elevator is already on the first floor, immediately open the elevator door and enter the firefighter's dedicated state.The treatment of general civil engineering problems on escalator sites: the beam edge distance is too large: in this case, 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,Sesena Household villa small elevator manufacturer, 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.Measurement of elevator and escalator shafts (III)

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.Elevator Tip : Why elevators can trap people? Every elevator door on each floor has a safety switch, which can trigger the elevator to shut down in case of any abnormality. The elevator getting stuck is actually when the system detects an abnormal signal and triggers a protective device, like braking to stop.The front room of the fire elevator is equipped with Class B fireproof doors or fireproof rolling shutters with stopping function.Welcome calls ,Electrical safety. Faulty elevators have multiple safety devices, but there are also many places where problems can occur. Some people have been caught due to abnormal door opening and closing,Sesena Household outdoor elevator on the third floor, while others have encountered situations where elevator buttons malfunction and the display screen is black, making it difficult to see the floor clearly. Some have experienced the danger of falling straight several floors. Although there may not have been any personal injury, taking the elevator is not about finding or acting in a movie. The real life is disturbed by the frequent elevator accidents, which make my heart feel uneasyIf the elevator is already on the first floor, immediately open the elevator door and enter the firefighter's dedicated state.Measurement of elevator shafts in new construction projects under different on-site conditions: When the building design is not yet completed, 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.

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.Quality risk,There is a dedicated fire telephone in the fire elevator car.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 front room of the fire elevator is equipped with indoor fire hydrants.Sesena ,The call button on each floor is no longer working, and the call is cut off.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 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
