Elevator does not close the door or repeatedly opens and closes the door: there are debris blocking the light curtain or door contact plate at the entrance or sill.
Passengers wearing long skirts and strapping sandals when riding on the escalator should try to stand slightly in the middle of the escalator to prevent shoes and clothing from being drawn into the escalator and causing danger, and to prevent skirts or pants from getting stuck.
Silverson.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,SilversonDouble column aluminum alloy lifting platform, and safety devices are debugged. Including non-destructive testing and maintenance of elevator traction steel wire ropes.
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?
.Factors to consider when choosing a household elevator: 1. Safety. Generally, brand elevators must have third-party testing, and elevators that have been inspected by professional organizations are safe, reliable, and guaranteed to be used with peace of mind. In addition, when choosing to purchase villa elevators, it is important to understand the safety components and configuration of this elevator. The essential safety equipment in the villa elevator includes a backup power supply and an emergency call outside telephone system to ensure the safety of private users on the elevator.

The elevator suddenly opens the door and does not move after leveling, but automatically resumes operation after a few minutes: The elevator (escalator) has been running for too long, and the motor overheats. To prevent burning out, the motor cools down and automatically resumes operation.
Elevator does not close the door or repeatedly opens and closes the door: there are debris blocking the light curtain or door contact plate at the entrance or sill.
Dragging Method&ndash& mdash; AC dual speed, Low speed elevators with frequency modulation and speed regulation often use AC dual speed (AC -) It changes the number of poles of the electric motor to achieve speed regulation, allowing the elevator to have a low-speed operation process before the leveling brake, while the main disadvantages are poor comfort. The straight elevator starts frequently, and the impact current during startup is too high, increasing power consumption. This type of elevator is now commonly used for freight elevators.
When accidentally trapped in an elevator, one should remain calm, press the alarm bell inside the elevator, and call the elevator emergency rescue phone or community property phone for help. Do not open doors or mess with buttons, which means it is in the braking state when there is no power, and only when it needs to be turned on, will the power turn on the brakes. So as soon as there was a power outage, the brakes closed and the elevator was braked in mid air. When the elevator descends abnormally, it is cut off

When accidentally trapped in an elevator, one should remain calm press the alarm bell inside the elevator, and call the elevator emergency rescue phone or community property phone for help. Do not open doors or mess with buttons, and patiently wait for rescue.
The seat elevator person sits on a chair driven by an electric motor, and the button on the chair handle causes the power drive device at the bottom of the chair to drive the person chair up and down along the guide rail of the staircase railing
Packaging strategy.The elevator suddenly opens the door and does not move after leveling, but automatically resumes operation after a few minutes: The elevator (escalator) has been running for too long, and the motor overheats. To prevent burning out, the motor cools down and automatically resumes operation.
The new technology of frequency regulation and voltage regulation (VVVF), abbreviated as Variable Voltage Variable Frequency in English, is based on the principles of electrical engineering. The speed and torque of the motor are directly proportional to the frequency and voltage amplitude of the AC power supply achieving accurate speed regulation and control of the motor. This speed regulation technology ensures smooth elevator operation, accurate leveling, and flexibility.
Mine elevators are used for transporting personnel and goods in mines. Special elevators are designed for special environmental conditions, such as explosion-proof, anti-corrosion, 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?
2. Different types of civil engineering traction elevators, screw elevators, 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 50cm or more; Additionally, there are certain requirements for the height of the top floor.
