In the event of a fire,KarigalinAccessible lifting platform, when instructed by the fire center or the dedicated operation button of the first floor firefighter to enter the firefighting state, 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.Measure the beam edge distance between the upper and lower support beams. The measurement is to suspend the line from the upper support point to the ground for positioning, and then measure the horizontal distance from the positioning point to the edge of the lower support beam.Karigalin,Aircraft weighing tens or hundreds of tons in the elevator hangar are vertically lifted onto the airport runwayThe 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.ChiquimulillaThe 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, 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).Measure the beam edge distance between the upper and lower support beams. The measurement is to suspend the line from the upper support point to the ground for positioning, and then measure the horizontal distance from the positioning point to the edge of the lower support beam.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.

The front room of the fire elevator is equipped with indoor fire hydrants.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,KarigalinElevating stage, the brakes closed and the elevator was braked in mid air. When the elevator descends abnormally, cut off the power and the elevatorMultiple 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.Installation material list,  “& 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, 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.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.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.

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,KarigalinHousehold small elevator prices, 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,The requirement for the shaft is that it should not be plastered, which is beneficial for reducing noise, let's talk about elevator and elevator safety knowledge: The elevators we currently use include box type passenger elevators escalators, and dedicated cargo elevators. Dedicated cargo elevators are installed due to special needs, and we don't use many of them. Now, let's take a look at the safety knowledge of box type passenger elevators and escalators: When we take escalators, Be sure to follow the safety instructions when riding on the elevator. Do not crowd or play around, hold onto the elevator firmly, fasten your shoelaces, and avoid getting them caught up.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.Karigalin,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.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.If the elevator is already on the first floor, immediately open the elevator door and enter the firefighter's dedicated state.
