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.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.Zanstad,Will the elevator quickly fall during a power outage& mdash;& mdash; Some movies and TV dramas often mislead the public into thinking that if the elevator loses its power, it will lose control and engage in falling movements.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,ZanstadHydraulic flipper manufacturer, changing the angle of the escalator from degrees to degrees can also make the beam edge distance longer.Tanguieta, 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, steel beams can be considered to be added between the frames for rectification.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.Restore the command button function in the cabin for firefighters to operate.

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.. Different types of civil engineering traction elevators, screw elevators, and hydraulic elevators have different requirements for civil engineering. Common traction elevators require a certain amount of hoistway space which can be made of concrete, steel structure hoistways, and glass curtain walls to create sightseeing elevators; The depth of the pit should be at least cm or more; Additionally, there are certain requirements for the height of the top floor.The call button on each floor is no longer working, and the call is cut off.Management Department,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, taking the elevator is not about finding or acting in a movie. The real life is disturbed by the frequent elevator accidents, which make my heart feel uneasyTower 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 call button on each floor is no longer working, and the call is cut off.

If the elevator is in a downward direction, immediately close the door and return to the first floor station, and automatically open the elevator door.High quality brand,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,ZanstadVertical obstacle free lifting platform, 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 difference between home elevators and ordinary public elevators is that the focus of home elevators and ordinary public elevators is different, with some indicators significantly reduced. For example, the load capacity of home elevators does not exceed kg, which is much lower than that of ordinary public elevators. Home elevators do not need to consider the issue of passenger flow, and the lifting speed is slower, ensuring safety. The lifting speed is generally between . to .m/s, and running smoothly.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.Zanstad,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 manufacturersIn the event of a fire, 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.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.
