and the area of the shared front room in public buildings and high-rise factory (warehouse) buildings is greater than square meters.The effective support width of the upper and lower support beams should be greater than the width of the escalator truss its area is: the area of the shared front room in residential buildings is greater than square meters

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, and there should be embedded steel plates.Swatpsk,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.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.San-Rafael-Arriba,To implement the arrangement of escalators and provide feedback, in order to determine the configuration of certain shared devices,SwatpskStage lighting elevator, the order of shipment, and the alignment of handrail turns during continuous arrangement.Measurement of elevator and escalator shafts (III)The speed limiter tensioning device and the steel belt tensioning device should be equipped with a safety switch.

Measurement of elevator and escalator shafts (III)There are many similar situations in daily life, such as forcefully opening the door inside the car, causing the circuit to disconnect and forcing the elevator to stop, resulting in people being trapped. For example, if the elevator frequently enters and exits during decoration and falls into the crack of the door, the elevator hall door may not be tightly closed, the elevator will stop. Professional quality assurance for home elevator manufacturers. Discount activities are underway, and new and old customers are welcome to come for consultationBrick 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.Safety production,The speed limiter tensioning device and the steel belt tensioning device should be equipped with a safety switch.There is a dedicated fire telephone in the fire elevator car.For escalators that require intermediate support, as well as the range of support that can be added, and other parameters.

If the elevator is already on the first floor, immediately open the elevator door and enter the firefighter's dedicated state.Manufacturing cost,SwatpskCost of small household elevators,Measure the length, width, and depth of the pit (if any), and observe whether there are grooves and embedded parts at the support beam.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 compensation chain and rope shall not collide with the shaft or other components during the operation of the elevator.Swatpsk,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.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.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, 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 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,SwatpskVilla Home Indoor Small Elevator, 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).
