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.
Wei Chen.The speed limiter tensioning device and the steel belt tensioning device should be equipped with a safety switch.
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, 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
.The gantry elevator is used in the door legs of large gantry cranes to transport workers and maintenance components inside the gantry crane

Aircraft weighing tens or hundreds of tons in the elevator hangar are vertically lifted onto the airport runway
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.
Measure the beam edge distance between the upper and lower support beams. The measurement is to suspend the line from the upper support point to the ground for positioning, and then measure the horizontal distance from the positioning point to the edge of the lower support beam.
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.
Total quality management.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, 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,Wei ChenMobile aluminum alloy lifting platform, 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.
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 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, 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
Highly recommended.These phenomena are not elevator malfunctions. When the elevator is fully loaded,Wei ChenHydraulic turnover machine, the elevator does not stop: to avoid overloading, the elevator car no longer responds to the next station's outbound call.
Reduce the overall noise of the machine. Due to the absence of noise from bearings during high-speed operation of an asynchronous motor and the absence of noise from worm gear transmission, the overall noise can be reduced by 5-10db (A) Low energy consumption. From the working principle of permanent magnet synchronous motors it can be seen that their excitation is achieved by permanent magnets, and there is no need for the stator to provide additional excitation current. Therefore, the power factor of elevators can reach a very high level. At the same time, the rotor of the motor has no current and there is no problem of electronic loss. Generally, it reduces consumption by 45% -60% compared to asynchronous motors. Due to the lack of low efficiency and high energy consumption worm gear transmission pairs, energy consumption is further reduced.

When wearing high heels, as not wearing shoes is more likely to be pinched by the toothed plate.
