Electrical components are roughly divided into screens, electrical switches for each safety circuit, etc. It is the brain of the elevator and the central nervous system of the elevator. The movement, operation, and door opening and closing of the elevator are all controlled by it, so it must be treated as a top priority in daily maintenance work. Do not short circuit the elevator circuit inside the screen during work. When the elevator door system malfunctions, someone shorts the elevator door for convenience in order to find the fault. This is very dangerous, and there are many accidents when shorting the door. Why? If a person opens the hall door and extends their head inward,San FranciscoSemi electric high-altitude reclaimer, the elevator happens to run up or down to this point, and the hall door is shorted,San FranciscoFixed stage elevator, the elevator cannot stop, so an accident is highly likely to occur. So in our daily maintenance work, we must not short-circuit the safety circuit. If it is necessary to short-circuit, we must identify which safety component has a problem and which safety component needs to be shorted. Moreover, after maintenance or urgent repairs are completed, we must promptly remove the short-circuit wire. Professional household elevator manufacturer, with a large quantity and excellent quality at a reasonable price. It is fire-resistant, waterproof, high-temperature resistant sturdy and durable, safe and reliableIf the elevator is already on the first floor, immediately open the elevator door and enter the firefighter's dedicated state.San Francisco,The elevator stops on a certain floor for a long time without moving or responding to external calls: it is possible that the elevator administrator has activated the driver operation function.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.Tutong,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 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, steel beams can be considered to be added between the frames for rectification.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, 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 manufacturers

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.Slide elevators are installed inside buildings and are often used parallel to buildings and sidewalksMeasure the length, width, and depth of the pit (if any) and observe whether there are grooves and embedded parts at the support beam.Quality improvement,To implement the arrangement of escalators and provide feedback, in order to determine the configuration of certain shared devices, the order of shipment, and the alignment of handrail turns during continuous arrangement.Measure the length, width, and depth of the pit (if any), and observe whether there are grooves and embedded parts at the support beam.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, and other parameters.

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.demand,The household must make two steel splints above the entrance. The position and size of the clamp plate are determined based on the selected door machine model.The elevator suddenly descends to the bottom floor and resumes normal operation: After the elevator is powered off and reconnected, the leveling reference position needs to be re determined.The speed limiter tensioning device and the steel belt tensioning device should be equipped with a safety switch.San Francisco,San FranciscoHousehold elevator for a three story villa,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 degreesMultiple 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.The basic content of escalator shaft measurement is to measure the lifting height. The same as measuring the height of a straight ladder, 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.

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
