HendersonGrainElevator 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.
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.
Henderson.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.
Household elevators must be regularly maintained to confirm their safety and whether they can continue to operate, while also repairing any faults and hidden dangers found.
.Slide elevators are installed inside buildings and are often used parallel to buildings and sidewalks

Dedicated cargo elevators are installed due to special needs,HendersonFixed stage elevator, 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, the elevator does not stop: to avoid overloading, the elevator car no longer responds to the next station's outbound call.
To implement the arrangement of escalators and provide feedback, in order to determine the configuration of certain shared devices, the order of shipment, and the alignment of handrail turns during continuous arrangement.

knowledge.The seat elevator person sits on a chair driven by an electric motor, and the button on the chair handle causes the power drive device at the bottom of the chair to drive the person chair up and down along the guide rail of the staircase railing
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.
Slide elevators are installed inside buildings and are often used parallel to buildings and sidewalks
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.
Project scope.The elevator stops on the first floor and the door does not move: the fire emergency landing function of the elevator is triggered by smoke or thermal sensors inside the building.
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,HendersonAluminum alloy high-altitude lifting platform, 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.
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, 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
Henderson.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.
The braking system of the elevator is usually closed, 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, and to prevent skirts or pants from getting stuck.
