Unique Pneumatic Booster Device Contained in the Semi-automatic Bollard

The semi automatic bollards have strong impact and shock resistance, and can be used to creatively protect railings in applications. They can be used in some sensitive areas: embassies, consulates, government agencies, banks, etc. Bollards are also called lifting ground bollards, lifting road piles, anti-collision road piles, hydraulic lifting bollards, isolation piles, etc.

1. The scope of application of semi automatic bollards

Bollards are widely used in many occasions such as urban traffic, the gates and surroundings of the military and important national institutions, pedestrian streets, highway toll stations, airports, schools, banks, large clubs, parking lots and so on. Through restrictions on passing vehicles, the traffic order and the safety of major facilities and places are effectively guaranteed. Its rise and fall can be automatically controlled by commands issued by authorized persons, or controlled by time setting. The semi automatic bollard has a double-acting hydraulic function and a hydraulic device that can automatically control the lifting.

2. The pneumatic booster for semi automatic bollards

The semi automatic bollards are usually suitable for passage control systems with high safety and low frequency of use. For economic reasons, they are often used in conjunction with automatic bollards. The semi automatic bollards have higher safety protection and avoid complex construction of strong and weak electricity. When the size of the bollard continues to increase with the improvement of safety requirements, the unique pneumatic booster device contained in the semi automatic bollard can bear a larger load. The lowering process of the semi automatic bollard is mainly realized by pressing down with the operator's own weight. When the top of the bollard reaches the ground level, the mechanical lock is self-locked and held. The lifting process of the ollard is 100% dependent on the release function of the pneumatic booster device inside the bollard. After the mechanical lock is released using a special key, the semi automatic bollard body automatically reaches the initial position and is self-locking without the need of applying external force.

The distance between the semi automatic bollard unit and the controller is not required, and it can ensure that multiple automatic bollards are synchronized. The semi automatic bollard has the characteristics of fast lifting speed and anti-collision. It can be controlled by wire and remote control, and can be controlled by computer. The semi automatic bollard system can effectively control the entry and exit of vehicles under the premise of ensuring smooth flow of people. The beautiful and gorgeous appearance design conforms to the design style of modern buildings, and the buried installation method will not destroy the original style of the building.

The semi automatic bollard means that the bollard body rises automatically, but its lowering relies on the manual assistance without the need of connecting to electricity; Rise: turn the key, the bollard automatically rises, and automatically locks when it rises to the specified height; fall: also turn the key to apply pressure on the top of the bollard, the bollard body is lowered back to the ground plane and locks automatically. By restricting passing vehicles, semi automatic bollards effectively guarantee the traffic order and the safety of major facilities and places. The semi automatic bollards are widely used at the entrances and exits with less passing vehicles. It consists of a bollard, a flange, a lifting guide system, a lifter, a lock control structure, and a buried box.
