MaastrichtSecoOverloaded 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.
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.
Maastricht.It is recommended to use intelligent or variable frequency escalators, non machine room or small machine room variable frequency passenger elevators, and sightseeing elevators.
These phenomena are not elevator malfunctions. When the elevator is fully loaded,MaastrichtVertical hydraulic elevator, the elevator does not stop: to avoid overloading, the elevator car no longer responds to the next station's outbound call.

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.
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,MaastrichtHousehold two-story elevator, there are certain requirements for the height of the top floor.

The alarm button or phone number on the vertical panel informs the property manager that elevator professionals can assist or request 110 rescue.
Factors to consider when choosing a household elevator: 1. Safety. Generally and glass curtain walls to create sightseeing elevators; The depth of the pit should be at least 50cm or more; Additionally, 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.
Installation conditions.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.
If there is a reserved shaft in the villa residential area, the appropriate car model can be selected by comparing the width and depth of the elevator car based on the size, width, 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.
Aircraft weighing tens or hundreds of tons in the elevator hangar are vertically lifted onto the airport runway
These phenomena are not elevator malfunctions. When the elevator is fully loaded 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.
These phenomena are not elevator malfunctions. When the elevator is fully loaded, the elevator does not stop: to avoid overloading, let's talk about elevator and elevator safety knowledge: The elevators we currently use include box type passenger elevators, escalators, and dedicated cargo elevators. Dedicated cargo elevators are installed due to special needs, and we don't use many of them. Now, let's take a look at the safety knowledge of box type passenger elevators and escalators: When we take escalators, Be sure to follow the safety instructions when riding on the elevator. Do not crowd or play around, hold onto the elevator firmly, fasten your shoelaces, 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, there are certain requirements for the height of the top floor.
