ระบบแกว่งเรือของเครื่องเล่น Twin Dragon - Siam Park City สวนสยามทะเลกรุงเทพ

This video shows how the Twin Dragon rides swing smoothly and constantly. There are two sets of driving tires under the ship. One turns to the left and the other to the right by hydraulic motors. These wheels are pressed against the bar under the ship alternately by a pneumatic cylinder. The entire system is automatically controlled. Unlike the other pirate ship ride, Twin Dragon has a free-swing mode that the drive wheel doesn't press. Give a natural, simple harmonic swing movement before braking.
