Automatic Bollards with Remote Control

The main reason why there are automatic bollards or automatic rising bollards is protection, security and control of access. It is mainly on highways and pedestrian zones so that access can be restricted there. If toll has to be collected or for some other reason access to the highway needs to be restricted, the automatic bollard is the answer. For pedestrian zones it is used, so that vehicular traffic does not encroach on these areas.

Automatic bollards are also installed in general car parking areas. Here it is not so much for security, but to ensure that drivers pay for the parking. The ticket issued after payment of parking fees enables the driver to open the bollard automatically.

Other areas where it is necessary is at high security access points and sensitive areas. Such areas are airports, military bases, palaces, public buildings, warehouses and train depots. These areas are generally cordoned off for normal public and the automatic bollard is convenient, because it can be opened by remote control if required. Military bases normally have a check-point and the bollard is automatically opened once the vehicle is thoroughly checked.

Most security professionals require today mobile access control devices to protect and guard their facilities. Hence they need some device which is powerful enough to stop a moving vehicle. The products have to be of the highest quality. They are installed by the company who manufacture them and they also provide after-sales service.

The automatic bollard consists of an automatic hydraulic bollard system. Cantilever sliding gates or sliding track gates are installed. It is possible to lower the whole bollard below ground to allow entry of a vehicle with the help of pneumatic power units. If there is a security threat the special emergency settings allow the posts to return automatically to an upright position.

Automatic bollards can open and close more than 100 times in a day. They work by radio frequency, though some options could be slower than others. They are generally used when the entrance and exit is used very frequently.

If the automatic bollard is a part of a larger access control system, the control device works well. However, there is often a combination of methods used to operate such devices like radio, remote control, card readers, keyswitch, numeric keypads or a push-button panel operated manually. Besides, most hydraulic units have back-up provisions to support during power failure.

Automatic bollards were installed around the U.S. courthouse in lieu of a terrorist attack. They were designed to stop a 7.5 ton truck traveling at 80 mph. Within 1.5 second thick steel plates would pop out of the ground automatically as soon as there was an emergency.

Safety is of the highest priority and concern and automatic bollards can be used against terrorism, because the whole system can be operated with remote control and the bollard can be built in such a way that it can stop up to 15-ton vehicles traveling at a speed of 44 mph. And the time to raise and lower the bollard into the ground just takes a second!
