Duff-Norton electro-mechanical actuators are the primary motion generating
components in non-hydraulic vehicle barriers, also referred to as bollard
posts. These devices are strategically positioned at vehicle entry points and
the bollards are raised and lowered to control the traffic and protect people
and property.
Vehicle barrier systems are used to protect high security installations such as
military bases, airports, state and federal buildings, embassies, nuclear and
coal fired power plants, and water treatment facilities. Other installations
include private and public buildings, sports complexes, schools, and parking
facilities.
Due to the government’s new requirement for high-speed bollard systems, our
customer selected the performance and reliability of the new Duff-Norton
SuperCylinder, which allows the bollards to be deployed in two seconds. Several
of these new high-speed vehicle barrier systems are installed at Baghdad
International Airport.
The Duff-Norton screw-drive SuperCylinder actuators are superior to hydraulic
and pneumatic actuation devices because of their dependability. They are the
preferred motion control product by the U.S. Government and others. Hydraulic
and pneumatic devices can develop hose or seal leaks and may not function when
a critical need arises.
Our new long life SuperCylinder actuators are used on many other linear motion
applications and are capable of providing linear speeds up to 6 inches per
second with capacities up to 25 tons. The SuperCylinder design provides an
ideal replacement for hydraulic and pneumatic cylinders.
