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

Aircraft weighing tens or hundreds of tons in the elevator hangar are vertically lifted onto the airport runway
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.
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.
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,MaesterFixed stage elevator, the rotor of the motor has no current and there is no problem of electronic loss. Generally, energy consumption is further reduced.
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, the brakes closed and the elevator was braked in mid air. When the elevator descends abnormally will the power turn on the brakes. So as soon as there was a power outage, it is cut off
Standard requirements.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.
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, we must stand firmly and support it well, screw elevators, and hydraulic elevators have different requirements for civil engineering. Common traction elevators require a certain amount of hoistway space,MaesterTwo roll hydraulic fully automatic plate rolling machine, which can be made of concrete, steel structure hoistways, and glass curtain walls to create sightseeing elevators; The depth of the pit should be at least 50cm or more; Additionally, there are certain requirements for the height of the top floor.
When accidentally trapped in an elevator, one should remain calm, press the alarm bell inside the elevator, and call the elevator emergency rescue phone or community property phone for help. Do not open doors or mess with buttons, and patiently wait for rescue.
technical service.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.
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, 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.
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, professional home elevators there are certain requirements for the height of the top floor.
Maester.Home elevators are different from special products such as public spaces, villa home elevators, home elevator manufacturers, and small home elevators. They are 20 year old brands with advantages in price and guaranteed quality. Considering the limited installation space, lack of dedicated hoistways, and small lifting height, they pursue simplicity and miniaturization in design, and the existence of computer rooms is not necessary. Long term promotion of a domestic elevator manufacturer, a 20 year old brand with competitive prices and guaranteed quality!
