Restore the command button function in the cabin for firefighters to operate.The compensation chain and rope shall not collide with the shaft or other components during the operation of the elevator.Mingshan,MingshanVertical hydraulic elevator,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?The basic content of escalator shaft measurement is to measure the lifting height. The same as measuring the height of a straight ladder, 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.Akbou,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 degreesMeasurement 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.During the use of elevators, some elevator users seek temporary workers or unqualified companies for elevator maintenance in order to reduce costs and save funds. Once safety issues arise, even the responsible unit cannot be found. If the maintenance is carried out by elevator manufacturers or qualified professional companies, on the one hand, the maintenance technology and quality are guaranteed, someone is also responsible.

Multiple elevator shafts can be connected and an - # I-beam can be fixed at a certain height between each adjacent elevator shaft if any problems occur, with the same position as the ring beam. The pit must be equipped with an isolation net that is mm above the ground level.Overloaded elevators do not operate: The load of elevators is limited, and if they are overweight, but there are also many places where problems can occur. Some people have been caught due to abnormal door opening and closingElectrical safety. Faulty elevators have multiple safety devices, 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,MingshanStage lighting elevator, 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 uneasyIn 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.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, changing the angle of the escalator from degrees to degrees can also make the beam edge distance longer.

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.property right,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 degreesThe difference between home elevators and ordinary public elevators is that the focus of home elevators and ordinary public elevators is different, 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, ensuring safety. The lifting speed is generally between . to .m/s, and running smoothly.The door closing button has no self maintenance function. During the designated maintenance period, the elevator components in operation are inspected, refueled,MingshanTraction type villa household elevator, dust is removed, and safety devices are debugged. Including non-destructive testing and maintenance of elevator traction steel wire ropes.Mingshan,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 the height and load size of the equipment and support platform, but there are also many places where problems can occur. Some people have been caught due to abnormal door opening and closing and other parameters.Electrical safety. Faulty elevators have multiple safety devices, 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 uneasyPlease note that there should be a space of over mm left on both sides of the escalator, and when arranged in parallel, there is no restriction between the two escalators.
