Boom barriers
Boom barriers (also known as boom gates), can be conceived of as gates which instead of opening in the horizontal plane, operate by rising and falling. They are typically pivoted on one side and counter weighted to allow smooth, easy manual operation. They can also be motorised and are usually painted in conspicuous colours such as with alternating red and white bands. To further increase their visibility, a second arm can be suspended around 300-400mm below the main arm by metalstraps which gradually revert to the vertical position as the boom is raised.
