A mechanical or hydraulic device is activated to hoist the section of the bridge, using a chain and pulley system. This mechanism is used to open up the water channel, allowing vessels to pass underneath or over the bridge. Drawbridges have also been used to protect towns and cities from attack, as they can form an effective barrier to access.
