but note that the range of shortening is very limited

The beam edge distance is too small: The method of shortening the lower platform is to shorten the total length of the escalator, 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 degreesDuring the use of elevators, some elevator users seek temporary workers or unqualified companies for elevator maintenance in order to reduce costs and save funds. Once safety issues arise, even the responsible unit cannot be found. If the maintenance is carried out by elevator manufacturers or qualified professional companies, on the one hand, the maintenance technology and quality are guaranteed, and on the other hand, if any problems occur, someone is also responsible.Uptar,Aircraft weighing tens or hundreds of tons in the elevator hangar are vertically lifted onto the airport runwayThe front room of the fire elevator is equipped with Class B fireproof doors or fireproof rolling shutters with stopping function.Tocoa,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.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.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.

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,UptarHousehold villa elevator manufacturer, 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,UptarCustomized household small elevator, changing the angle of the escalator from degrees to degrees can also make the beam edge distance longer.Mine elevators are used for transporting personnel and goods in mines. Special elevators are designed for special environmental conditions, anti-corrosion, and heat-resistant elevatorsMeasure the length, width, and depth of the pit (if any), and observe whether there are grooves and embedded parts at the support beam.Job description,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.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, 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.Measurement of elevator shafts in new construction projects under different on-site conditions: When the building design is not yet completed, the operator only needs to provide the user with the standard elevator layout of the required elevator specifications, and the user entrusts the design department to design the elevator shaft. When the architectural design has been completed, and the site has not yet been constructed, is under construction, or has been completed, it must be determined based on the current construction or measured dimensions. If the original civil design of the shaft needs to be modified, the user should entrust the architectural design department to make the shaft design modification based on the layout provided by the elevator.

The position and size of the clamp plate are determined based on the selected door machine model.Factors to consider when choosing a household elevator: . Safety. Generally, brand elevators must have third-party testing, and elevators that have been inspected by professional organizations are safe, when choosing to purchase villa elevators and guaranteed to be used with peace of mind. In addition, it is important to understand the safety components and configuration of this elevator. The essential safety equipment in the villa elevator includes a backup power supply and an emergency call outside telephone system to ensure the safety of private users on the elevator.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.Uptar,Maintenance of elevator hall doors and car doors. Elevator malfunctions usually occur on the elevator hall and car doors,UptarFlip plate hydraulic roadblock machine, 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, so that the elevator will not make unpleasant noises during operation and the opening of the door. Pay attention to the inspection of the safety contact plate or light curtain type contact plate switch wire of the elevator, 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.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, immediately close the door and return to the first floor station, and automatically open the elevator door.
