The call button on each floor is no longer working, and the call is cut off.The gantry elevator is used in the door legs of large gantry cranes to transport workers and maintenance components inside the gantry crane “& 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, etc. can meet the installation requirements of the elevator, as well as which building structures are needed (such as smashing stairs or floors), door opening width, etc.), then consider the non-standard design of the elevator.assets,Electrical components are roughly divided into screens,RouenFixed lifting stage, electrical switches for each safety circuit, etc. It is the brain of the elevator and the central nervous system of the elevator. The movement, operation, and door opening and closing of the elevator are all controlled by it, so it must be treated as a top priority in daily maintenance work. Do not short circuit the elevator circuit inside the screen during work. When the elevator door system malfunctions, someone shorts the elevator door for convenience in order to find the fault. This is very dangerous, and there are many accidents when shorting the door. Why? If a person opens the hall door and extends their head inward, the elevator happens to run up or down to this point, and the hall door is shorted, the elevator cannot stop, so an accident is highly likely to occur. So in our daily maintenance work, we must not short-circuit the safety circuit. If it is necessary to short-circuit, we must identify which safety component has a problem and which safety component needs to be shorted. Moreover after maintenance or urgent repairs are completed, we must promptly remove the short-circuit wire. Professional household elevator manufacturer, with a large quantity and excellent quality at a reasonable price. It is fire-resistant, waterproof, high-temperature resistant, sturdy and durable, safe and reliableIf the elevator is already on the first floor, immediately open the elevator door and enter the firefighter's dedicated state.The front room of the fire elevator is equipped with indoor fire hydrants.
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.Honest service,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, 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.In daily life, elevators are a commonly used tool that brings us a lot of convenience. But how much do you know about the types and safety knowledge of 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.Rouen,Attention: The elevator consists of two main parts: mechanical and electrical. If the elevator is not maintained on a daily basis, its safety cannot be guaranteed. If the elevator needs to be refueled without refueling, it will cause wear and tear on the mechanical components of the elevator, greatly shortening its service life and preventing normal use of the elevator.The compensation chain and rope shall not collide with the shaft or other components during the operation of the elevator.In 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,RouenDuplex villas stacked with household elevators, 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.
