The Castle Drawbridge - A Modern Bascule Bridge The Drawbridge is now described as a Bascule type of bridge - a bascule bridge tilts upward to open. The drawbridge works by counterbalance so that when one end is lowered the other is raised - so that when one end is lowered the other is raised - the seesaw principle - moved by weights. Parts of a Medieval Drawbridge Some of the working parts of a Medieval drawbridge are described as follows: - Rainures or Gaffs were the recesses for the counterbalance beams
- Trunnions were axles on which a drawbridge turned - one of a pair of projecting pivots
- Windlass was a mechanical device used to raise and lower the drawbridge
A late design of the Drawbridge combined its mechanism with that of the Portcullis - when the Portcullis was dropped the Drawbridge was automatically raised. The Drawbridge The Drawbridge was introduced with Norman and Plantagenet castles during the Medieval period 1066 - 1485.
