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.Dusseldorf,Overloaded elevators do not operate: The load of elevators is limited, and if they are overweight they will alarm and generally cannot be started. Most passengers can also voluntarily exit.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, support needs to be added in the middle of the escalator truss. In addition, changing the angle of the escalator from degrees to degrees can also make the beam edge distance longer.BalbrigganIf the elevator is already on the first floor, 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,DusseldorfHydraulic fully automatic plate rolling machine, 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 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, 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).

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 manufacturersThe elevator stops on a certain floor for a long time without moving or responding to external calls: it is possible that the elevator administrator has activated the driver operation function.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.Test results,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 door closing button has no self maintenance function. During the designated maintenance period, the elevator components in operation are inspected, refueled, dust is removed, and safety devices are debugged. Including non-destructive testing and maintenance of elevator traction steel wire ropes.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 safety monitoring machine room environment screen cabinet main power switch traction wheel speed limiter shaft and pit guide rail layer door and car counterweight should be reliably fixed with pressure plates to prevent loosening.Industry management,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, the user should entrust the architectural design department to make the shaft design modification based on the layout provided by the elevator.. 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.Restore the command button function in the cabin for firefighters to operate.Dusseldorf,DusseldorfHydraulic turnover machine,　　“& 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 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,DusseldorfStage boom elevator, 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.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.
