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.Electrical components are roughly divided into screens,UptarManufacturer of automatic flipper, 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, the elevator happens to run up or down to this point, and the hall door is shorted, the elevator cannot stop, so an accident is highly likely to occur. So in our daily maintenance work, 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,Uptar3-story small household elevator, waterproof, high-temperature resistant, sturdy and durable, safe and reliableUptar,These phenomena are not elevator malfunctions. When the elevator is fully loaded, the elevator does not stop: to avoid overloading, the elevator car no longer responds to the next station's outbound call.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.Aguascalientes,The front room of the fire elevator is equipped with Class B fireproof doors or fireproof rolling shutters with stopping function.Maintenance of elevator hall doors and car doors. Elevator malfunctions usually occur on the elevator hall and car doors 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, 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.Please 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.

The speed limiter tensioning device and the steel belt tensioning device should be equipped with a safety switch.Household elevators must be regularly maintained to confirm their safety and whether they can continue to operate, while also repairing any faults and hidden dangers found.b. When the old elevator cannot start: due to the inability to enter the shaft, limited data can only be obtained from outside the shaft to determine whether it is non-standard (if there is a high platform in the machine room, the plane size of the shaft can be measured in the machine room, but it is not accurate enough) for elevator quotation negotiation reference. In this case, the signing of the contract should state that the shaft rectification and costs are the responsibility of the user. For uncertain shaft structures and dimensions, users should be reminded to provide them to the elevator after the old elevator or notify the elevator to take measurements before the new elevator is put into operation.Standard requirements,The front room of the fire elevator is equipped with Class B fireproof doors or fireproof rolling shutters with stopping function.The basic content of escalator shaft measurement is to measure the lifting height. The same as measuring the height of a straight ladder, strictly speaking, 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.The front room of the fire elevator is equipped with indoor fire hydrants.

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.Standard requirements,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, 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 measuring personnel observe and measure the full travel of the shaft from the top 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).The gantry elevator is used in the door legs of large gantry cranes to transport workers and maintenance components inside the gantry craneBrick 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,UptarHydraulic unloading and tipping machine, steel beams can be considered to be added between the frames for rectification.Uptar,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 manufacturers　　“& 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 call button on each floor is no longer working, and the call is cut off.
