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.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, 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 brackets, whether there are special structures on the shaft wall, the spacing between ring beams, 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).Pittsburgh,Mine elevators are used for transporting personnel and goods in mines. Special elevators are designed for special environmental conditions, such as explosion-proof anti-corrosion, and heat-resistant elevators　　“& rdquo; Elevator shaft: The design conditions are provided by the user to the architectural design department. The architectural design department analyzes whether the on-site pit depth top floor height, reaction force,PittsburghHousehold elevator for a three story villa, etc. can meet the installation requirements of the elevator, as well as which building structures are needed (such as smashing stairs or floors), and develops a renovation construction plan. If it is indeed necessary to change the elevator structure due to civil engineering conditions (such as car size, door opening width, etc.), then consider the non-standard design of the elevator.Clonmel,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, and on the other hand, 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.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, 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, which make my heart feel uneasy

The speed limiter tensioning device and the steel belt tensioning device should be equipped with a safety switch.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.Attention: The elevator consists of two main parts: mechanical and electrical. If the elevator is not maintained on a daily basis, its safety cannot be guaranteed. If the elevator needs to be refueled without refueling, it will cause wear and tear on the mechanical components of the elevator, greatly shortening its service life and preventing normal use of the elevator.Installation material list,Cleaning and cleaning of elevator car guide shoes. As is well known, the guide shoe runs on the guide rail, and there is an oil cup on the guide shoe. To ensure that the elevator does not make any noise during operation, it is necessary to regularly refuel the oil cup and clean the guide shoe, and the cabin should be cleaned thoroughly.There is a dedicated fire telephone in the fire elevator car.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,PittsburghHousehold outdoor elevator on the third floor, 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.

The speed limiter tensioning device and the steel belt tensioning device should be equipped with a safety switch.Statistics,The effective support width of the upper and lower support beams should be greater than the width of the escalator truss,PittsburghHousehold elevator, and there should be embedded steel plates.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, the brakes closed and the elevator was braked in mid air. When the elevator descends abnormally, cut off the power and the elevatorThe compensation chain and rope shall not collide with the shaft or other components during the operation of the elevator.Pittsburgh,If the elevator is in a downward direction, immediately close the door and return to the first floor station, the lighting inside the non fire elevator has no power, while there is still lighting inside the fire elevator.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.
