They are among the barrier types used at entrances and gates requiring high security. They can be manufactured in hydraulic, pneumatic, electro-mechanical types. Bollards are among frequently demanded barrier products with their high impact resistance, weather resistant structure at places with parking problems because without impeding pedestrian crossings, they do not permit vehicles to pass.

 

It consists of 2 sections; the main unit (hydraulic system) and the bollard section. They operate by transmitting hydraulic fluid pressurized by means of the hydraulic pump to the hydraulic piston. They are manufactured to be resistant to heavy weather conditions (temperature, humidity, frost, rain, etc.) for many years.

 

2- Pneumatic Type Bollard: It consists of 2 sections; the main unit (compressor and air unit) and the bollard section. They operate by transmitting pressurized air produced in a special compressor air unit to the pneumatic pistons.

 

3- Electro-mechanical Type Bollard: It operates with electric engine and reduction gear drive principle.
