When wearing high heels,HajidunasMobile reclaimer, 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.

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.

Hajidunas.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.

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

.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.

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.

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.

Brick concrete structure elevator shaft: For unfinished brick structure shafts users can be required to make a circle of beams at a certain height, arranged on three sides, and disconnected on one side of the elevator entrance. The distance between the center heights of the beams depends on the product model, and should not exceed 2500mm. The beam height should be 300mm, and the thickness should be the same as the wall. The lower ring beam is 500-1500mm away from the bottom of the pit, and the user is responsible for providing materials and construction. If the shaft structure is made of hollow bricks without ring beams, steel beams can be considered to be added between the frames for rectification.

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, it will lose control and engage in falling movements.

Inspection environment.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.

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

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.

Quality department.The elevator suddenly opens the door and does not move after leveling, and the motor overheats. To prevent burning out, the motor cools down and automatically resumes operation.

The main parameters that determine the conveying capacity are escalators: quantity,HajidunasHome villa sightseeing elevator, clear width of steps, inclination angle, elevator: rated load, rated speed, large lifting height, quantity, number of floors and stations.

There are many similar situations in daily life, causing the circuit to disconnect and forcing the elevator to stop, resulting in people being trapped. For example, 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,HajidunasGrain hydraulic flipper, 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

As elevator people, let's talk about elevator and elevator safety knowledge: The elevators we currently use include box type passenger elevators, escalators, 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.

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.
