Maester.It is not recommended to force doors or self rescue from car roof safety windows. Because climbing out of the car is not equivalent to rescue, most passengers are unfamiliar with the elevator shaft and elevator structure, the appropriate car model can be selected by comparing the width and depth of the elevator car based on the size, width,MaesterFully electric high-altitude reclaimer, and depth of the shaft. If there is no reserved shaft, you can first choose the model of the elevator and create a new shaft based on the required reserved size space for different models.
The elevator suddenly descends to the bottom floor and resumes normal operation: After the elevator is powered off and reconnected, the leveling reference position needs to be re determined.

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 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.
quality index.There are many similar situations in daily life, such as forcefully opening the door inside the car, causing the circuit to disconnect and forcing the elevator to stop, resulting in people being trapped.

2. 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, with some indicators significantly reduced. For example, the load capacity of home elevators does not exceed 400kg, and the lifting speed is slower, ensuring safety. The lifting speed is generally between 0.3 to 0.4m/s, and running smoothly.
