The happiest part of childhood was going to the amusement park. Every amusement park has big rides, and I think the most exciting one is the pendulum.

The working principle of the big pendulum is: the main part is driven by a motor to push the slewing bearing, so that the motor can flexibly track the swing of the pendulum, to achieve non-uniform rotation. 

There are many sources of power for the big pendulum, including electrical trends, wind-up gears, and the gravity of the hammer moving back and forth between points. Super big pendulum, also known as big pendulum, meteor hammer, is becoming the international popular new amusement equipment, is also one of the most popular amusement park projects.
