China Elevator Lifts Factory introduced the selection requirements for elevator selection:
2. If there is no hoistway, installing elevators indoors or outdoors requires the construction of a hoistway or the construction of a steel structure hoistway. The price of the steel structure hoistway is roughly the same as the price of the elevator, and now the price of steel has risen. The steel structure hoistway is divided into tempered glass, fireproof board, and so on.
3. Whether it is good or bad, the feeling of the elevator in use cannot be unilaterally distinguished by the strength of the manufacturer and the production volume of the factory. In the elevator industry, this sentence is the same: 3 points depending on the quality and 7 points depending on installation and maintenance.
4. The elevator uses a traction machine (main engine, a motor similar to an engine) to pull the car (space where you ride) on the track (passenger elevators usually use 89 guide rails and 75, etc.). Bad manufacturers reduce distribution profits Increased, the quality is worrying, I dare not sell it, for example, if your guide rail is bent, then the best elevator is futile, shaking and creaking. I have seen too many first-tier brands of elevators installed poorly.
