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.

Aircraft weighing tens or hundreds of tons in the elevator hangar are vertically lifted onto the airport runway

Cross sign.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, and high coercive force neodymium iron boron. Its air gap magnetic density generally reaches over 0.75T, so it can achieve small volume and light weight.

Slide elevators are installed inside buildings and are often used parallel to buildings and sidewalks

.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.

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.

The braking system of the elevator is usually closed,Cross signStage main lifting platform, which means it is in the braking state when there is no power, 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

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. For example,Cross signHousehold seat elevator, if the elevator frequently enters and exits during decoration and falls into the crack of the door, the elevator hall door may not be tightly closed, and after several consecutive doors are opened and closed, the elevator will stop. Professional quality assurance for home elevator manufacturers. Discount activities are underway and new and old customers are welcome to come for consultation

Comfort mainly refers to the sensory impact of elevator acceleration, vibration, noise, decoration, lighting and other indicators on people. The noise is mainly generated by the traction machine so it is necessary to choose a traction machine with low noise. The system can reduce vibration and increase comfort.

Safety and health.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

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.

As elevator people, 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, and avoid getting them caught up.

When wearing high heels, be careful not to step on the gap between the pedals, as not wearing shoes is more likely to be pinched by the toothed plate.

Total quality management.The gantry elevator is used in the door legs of large gantry cranes to transport workers and maintenance components inside the gantry crane

The treatment of general civil engineering problems on escalator sites: the beam edge distance is too large: in this case, the length of the upper and lower platforms of the escalator can be increased to meet the actual dimensions of civil engineering. One platform can be extended on one side, or both platforms can be extended simultaneously. The total extension of the upper and lower platforms should generally not exceed 1000mm. When lengthening the platform, which should also be lengthened at the same time. After the escalator is extended, the force on the upper and lower support points will also increase. If the edge distance of the beam increases too long, support needs to be added in the middle of the escalator truss. In addition, changing the angle of the escalator from 35 degrees to 30 degrees can also make the beam edge distance longer.

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.

Cross sign.The braking system of the elevator is usually closed, 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 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,Cross signFixed lifting rotating stage, ensuring safety. The lifting speed is generally between 0.3 to 0.4m/s, 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.
