Q:Such as title

There is the elevator building, ah, generally refers to the residential building.

Q:What are the embedded parts in the elevator shaft?

Most of the embedded parts made of metal, such as: steel or cast iron, wood, plastic and other non-metallic rigid materials. The prefabricated part (prefabricated part) is a pre-installed (buried) component in the concealed project, that is, the structure of the structure when the structure is placed, for the masonry when the superstructure of the lap. To facilitate the installation of external engineering equipment base fixed.

Q:What is the meaning of E and F in the elevator?

To see what model you are the elevator alone is a letter can not answer the elevator and elevator models represent the meaning of different

Q:Elevator to the second floor, when the man turned out and smiled at her. When the door closes, she suddenly darling up to the third floor .. The woman is dead. Q: Do not cancel the third floor of the case how can let her survive? More

Shibi problem, why do not kill in the elevator, why the door closed also laugh knife also dig a knife. What a messy assumption

Q:The woman came home and found to be a man tracking ... ... ... ... elevator to the second floor, the man turned out when she smiled ... when the door closed, she suddenly saw the man took out the knife to the third floor ... the results of a woman died. Q: Do not cancel the third floor of the case how can let her survive? More

In fact, this problem is only a mess of our ideas. The elevator can not cancel the third floor, just closed when you can press the door button, open the door immediately rushed to the first floor, the elevator door will automatically shut down to the third floor. At this time to the first floor she can be rescued.

Q:Who can talk about the details of the use of contactors on the elevator, I have come into contact with some of the circuit can see a little bit to understand, but in fact to Mongolia, who can elaborate on what, the best example, such as Some of the contacts of the contactor, interlock, the purpose is to see the intestinal 礌 spotting alone do sweepers of the contactor I can understand which line is the coil, which line is the main contact, which is Interlocking, and some other what, depressed do not know even asked do not know how to ask, who can elaborate under the big brother. More

The upper side of the coil is marked A1 and A2 is the two points of the coil. (NC) Most of the points are often used to open the signal point, the main contactor you must understand, like the door lock contactor, emergency stop contactor, brake contactor, In addition to the coil point, normally open normally closed are part of the detection circuit, to a part of the signal, the process is to monitor the elevator power phase sequence, the correct after the main power contactor pull, emergency stop loop, emergency stop contact (110V, 36V), often open point to the motherboard signal, the inverter signal, the operation of the contactor signal, the door is closed, then the door contactor pull, and then the door line, elevator, inside the security line (110V, 36V) (110V, 36V), often open the closed point to the motherboard signal, the system signal, run the contactor signal, run the contactor coil is given by the emergency stop contactor signal and door lock contact The signal is given in series, the first two contactors closed, then run the contactor to meet the conditions closed, the coil point also need to give the motherboard control line running signal, and finally the brake contactor pull, feedback a holding point , This is mostly long closed Intestine spotted spotted posture. You better or more to observe its run-time contact closure of the order, no more difficult to see a few times to see clearly, there is more simple drawings, it is best not to see the drawings, easy to Mongolia, on their own To think, and then go to the drawings contrast, see do not need to understand later, remember solid. And then tell you a study of the ruthless strokes · ordinary people I do not tell him ~ ~ ~ ~ Oh turn off the elevator power, the contact with things stuffed, so that they pull, you use the table which point and which point, after their own Draw a simple circuit diagram, then disconnect the amount. Technology this thing is not who taught, are stolen ~ ~ ~ ~ ~ ~ ~ ~ ~ ~

Q:Why is the elevator in the Zifu Fu letter of the gearless traction machine do not use the upstream overspeed protection of the rope device? More

Because the wheel on the traction wheel of the elevator is improved! The elevator gravity is safe on the wheel

Q:Solve this problem.

A comb can be resolved from the bag out of the comb, the elevator shut the door quickly into the comb, the door opened, the culprits have rushed to the third floor

Q:The main difference between the elevator and the engine room elevator on the installation

* The structure is different: the organic room is in the top of the hoistway there is a room, no machine room without the engine room. * Motor and control cabinet installation location is different: the engine room of the motor and control cabinet installed in the engine room; Usually on the rail, the upper part of the hoistway, the control cabinet installed in the shaft on the wall, but also installed in the top of the ride on the wall. * The difference between emergency operations: organic room in the engine room for emergency operations; For the maintenance of the motor and the control cabinet, the machine room should be operated on the top of the car.

Q:I wear touch flat bark strong Du Zhicheng platinum is a property management novice, because the Lord to me to reflect the elevator did not signal. I do not know if this is related to the property?
