Rotating Bridge Mechanism System.doc

Rotating bridge mechanism system Abstract A swing bridge is a movable bridge that has as its primary structural support a vertical locating pin and support ring, usually at or near to its center of gravity, about which the turning span can then pivot horizontally as shown in the animated illustration to the right. Small swing bridges as found over canals may be pivoted. Rotating Bridge Automation Project Purpose the aim for this project is to create a three dimensional model of a rotating or swinging bridge similar to the one in Northwick Town England What is a Rotating Bridge? A swing bridge is a movable bridge that has as its primary structural support a vertical locating pin and support ring which allows it to pivot horizontally. Advantages The chances of collisions is greatly reduced in the presence of a rotating bridge. The bridge requires no counterweights so its complete weight is significantly reduced.
