polandRotatingThese phenomena are not elevator malfunctions. When the elevator is fully loaded, the elevator does not stop: to avoid overloading,polandHydraulic barrier free elevator, the elevator car no longer responds to the next station's outbound call.
Slide elevators are installed inside buildings and are often used parallel to buildings and sidewalks
poland.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,polandHousehold small elevator prices, accurate leveling, and flexibility.
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.
.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
Elevator Tip 1: Why elevators can trap people? Every elevator door on each floor has a safety switch, which can trigger the elevator to shut down in case of any abnormality. The elevator getting stuck is actually when the system detects an abnormal signal and triggers a protective device, like braking to stop.

The elevator getting stuck is actually when the system detects an abnormal signal and triggers a protective device, like braking to stop.
The braking system of the elevator is usually closed, which means it is in the braking state when there is no power, and only when it needs to be turned on,polandGrain hydraulic flipper, 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
Drive Method&# 8217& mdash; The advantages of worm gear traction machines and permanent magnet synchronous gearless traction machines compared to worm gear traction machines are: simple and compact structure, small volume, and light weight. Due to the fact that the permanent magnet synchronous traction machine is directly driven, without worm gear or worm drive, and without the stator coil that occupies a significant amount of space required for asynchronous motors, its main material is high energy density, high residual magnetic induction, so it can achieve small volume and light weight.

Executive standard.When encountering abnormal elevator operation, you can call the repair hotline to consult with the maintenance personnel or inform the service center to handle it. Do not take unauthorized measures to avoid causing greater harm to the elevator or even causing casualties.
When passengers are riding on the escalator, they may lose their balance and fall due to leaning against the skirt board on the side of the escalator, which does not move, but their feet move with the steps. Especially when carrying a lot of packages while taking the elevator, it is more likely to fall on the escalator due to the inability to hold the handrail properly. So, when riding on the escalator, and the motor overheats. To prevent burning out but automatically resumes operation after a few minutes: The elevator (escalator) has been running for too long it will lose control and engage in falling movements.
High value.The elevator suddenly opens the door and does not move after leveling and do not lean against the skirt board on the side of the escalator.
The gantry elevator is used in the door legs of large gantry cranes to transport workers and maintenance components inside the gantry crane
Will the elevator quickly fall during a power outage& mdash;& mdash; Some movies and TV dramas often mislead the public into thinking that if the elevator loses its power, the motor cools down and automatically resumes operation.
No oil pollution. Due to the absence of tooth profile wear issues and the need for regular oil replacement, it has a long service life, reduces oil pollution, and reduces maintenance
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, 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.
poland.The difference between home elevators and ordinary public elevators is that the focus of home elevators and ordinary public elevators is different, with some indicators significantly reduced. For example, the load capacity of home elevators does not exceed 400kg, which is much lower than that of ordinary public elevators. Home elevators do not need to consider the issue of passenger flow, and the lifting speed is slower, ensuring safety. The lifting speed is generally between 0.3 to 0.4m/s, and running smoothly.
Overloaded elevators do not operate: The load of elevators is limited, and if they are overweight, they will alarm and generally cannot be started. Most passengers can also voluntarily exit.
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.
