Vibration problem in elevator operation
An elevator is an electromechanical device that carries objects by moving the car. During the operation of the elevator, the car of the elevator will vibrate with the movement, which is the most common problem of the elevator. The vibration will be comfortable for the passengers. The main factors are as follows:
1. The mechanical movement part of the traction machine is the most common source of vibration. It is necessary to select a traction machine with high bearing precision and high installation accuracy.
2. The base of the mainframe is supported on the load-bearing beam. If there is no isolation rubber, the vibration of the traction machine will be transmitted to the machine room and the hoist-way through the load-bearing beam. Therefore, the rubber is required to be isolated.
3. The suspension center of the car deviates or compensates for the suspension of the cable, and the eccentric load of the car causes the car to generate an unbalanced force, causing a strong jitters.
4. The jitters caused by the uneven torque and tension of the wire rope.
5. The verticality of the car rail installation and the gap and step of the rail joint are important reasons for horizontal vibration. Strict quality control is required for the mounting and installation of rail brackets and guide rails.

Elevator safety equipment- speed governor
The elevator speed governor is one of the safety control components in the elevator safety protection system.
When the elevator is running for any reason, if the car is over speed-ed, and even the danger of falling, and all other safety protection devices are not working, the speed limiter and the safety gear are linked to cause the elevator car to stop. live. It is the safety protection device of the elevator. It monitors and controls the speed of the car at any time. When there is an over-speed condition, that is, 115% of the rated speed of the elevator, it can send a signal in time, and then generate a mechanical action to cut off the power supply circuit and brake the traction machine. If the elevator still cannot brake, the safety gear installed at the bottom of the car will force the car to stop. The speed limiter is the command sender and the safety gear is the performer. The combination of the two has emerged as a safe elevator.
The speed limiter safety clamp system is an indispensable safety device for the elevator. When the elevator is over-speed, the operation is out of control, or the suspension device is broken, the speed limiter safety clamp device quickly stops the elevator car on the guide rail and remains stationary. Avoid casualties and equipment damage.

The function of escalator brush
In addition to the escalator in the mall is the escalator. ~Do netizens know what they use the two brushes on the escalator? Curiosity drives me to understand. Here's my report.
Let's first take a look at the guesses of netizens:
Most netizens guess it's shoe-brushing. After all, it's brush.
Some netizens speculate that it is convenient to clean up the elevator and brush it down directly. Is it a little too long?
Okay, serious.
In fact, there are legal provisions to install brushes on escalators. "The accident risk can be reduced by installing anti-clip devices between the left and right sides of escalator and apron plate."
The anti-clip device here refers to the brush, which prevents the big guys from accidentally clipping their feet in the gap between the pedal and the edge, causing accidents.
