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.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, greatly shortening its service life and preventing normal use of the elevator.Hajidunas,The elevator stops on the first floor and the door does not move: the fire emergency landing function of the elevator is triggered by smoke or thermal sensors inside the building.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.Glasgow,HajidunasSightseeing elevator household use, 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.

In addition,HajidunasCost of small household elevators, changing the angle of the escalator from degrees to degrees can also make the beam edge distance longer.Brick concrete structure elevator shaft: For unfinished brick structure shafts, users can be required to make a circle of beams at a certain height, arranged on three sides, and disconnected on one side of the elevator entrance. The distance between the center heights of the beams depends on the product model, and should not exceed mm. The beam height should be mm, and the thickness should be the same as the wall. The lower ring beam is -mm away from the bottom of the pit, and the higher ring beam is -mm away from the lower surface of the shaft roof. The completed framework with a solid brick structure shaft can be equipped with steel plywood at the position of the fixed guide rail support frame. The position and size of the plywood are provided by the elevator, and the user is responsible for providing materials and construction. If the shaft structure is made of hollow bricks without ring beams, steel beams can be considered to be added between the frames for rectification.The compensation chain and rope shall not collide with the shaft or other components during the operation of the elevator.

  “& 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, 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.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.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,HajidunasHome elevator villa self built house, 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, 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).target,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.If the elevator is already on the first floor, immediately open the elevator door and enter the firefighter's dedicated state.Tower style residential buildings above; Residential units and corridors with twelve or more floors; Other Class II public buildings with a building height exceeding meters; High rise buildings with elevators exceeding meters in height; The functional fire elevator has a front room. The area of the independent fire elevator front room is: the front room area of the residential building is greater than square meters; The front room area of public buildings and high-rise factory (warehouse) buildings is greater than square meters. When the front room of the fire elevator is shared with the smoke proof staircase, 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.

As is well known, it is necessary to regularly refuel the oil cup and clean the guide shoe, and the cabin should be cleaned thoroughly.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 elevatorThe 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.Hajidunas,There is a dedicated fire telephone in the fire elevator car.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.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 degrees
