Abstract

See full text

A gravity drawbridge is a moveable bridge that utilizes gravity and fluid transport to transition a bridge deck between an open configuration and a closed configuration. The gravity bridge includes a fulcrum, a first fluid reservoir, a second fluid reservoir and a fluid pump. The first fluid reservoir and the second fluid reservoir are internally mounted within the bridge deck. The first fluid reservoir and the second fluid reservoir are in fluid communication to each to transport a quantity of fluid between the first fluid reservoir and the second fluid reservoir using the fluid pump. The bridge deck rotates about the fulcrum as the quantity of fluid is transported between the first fluid reservoir and the second fluid reservoir to transition the bridge deck between the open configuration and the closed configuration.
