MessinaFixed lbe careful not to step on the gap between the pedals, as not wearing shoes is more likely to be pinched by the toothed plate.
Messina.High transmission efficiency. Due to the use of permanent magnet synchronous motors for direct drive the transmission efficiency can be improved by 20% -30%.
Aircraft weighing tens or hundreds of tons in the elevator hangar are vertically lifted onto the airport runway
.In daily life, elevators are a commonly used tool that brings us a lot of convenience. But how much do you know about the types and safety knowledge of elevators?
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.
Passengers wearing long skirts and strapping sandals when riding on the escalator should try to stand slightly in the middle of the escalator to prevent shoes and clothing from being drawn into the escalator and causing danger, and to prevent skirts or pants from getting stuck.
Factors to consider when choosing a household elevator: 1. Safety. Generally, 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.
The effective support width of the upper and lower support beams should be greater than the width of the escalator truss, and there should be embedded steel plates.
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, and heat-resistant elevators
Direct labor.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.
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.
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 it is cut off

Create brilliance.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.
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, so it can achieve small volume and light weight.
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,MessinaStage banner elevator, the brakes closed and the elevator was braked in mid air. When the elevator descends abnormally, it is cut off
Messina.The elevator suddenly descends to the bottom floor and resumes normal operation: After the elevator is powered off and reconnected,MessinaStage lighting elevator, the leveling reference position needs to be re determined.
Passengers wearing long skirts and strapping sandals when riding on the escalator should try to stand slightly in the middle of the escalator to prevent shoes and clothing from being drawn into the escalator and causing danger, and to prevent skirts or pants from getting stuck.
When accidentally trapped in an elevator,MessinaTwo roll hydraulic fully automatic plate rolling machine, 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.
