Stainless Steel Automatic Rising Bollards

this is new designed electric-hydraulic operated retractable bollard for roadblock management.
the system can be quickly and easily operated, suitable for both security and access control applications.
the system is designed to bring convenience and enhancements to higher level security. it is ideal choice for universities, pedestrian sidewalks, parking lots, government buildings, gyms, amusement parks, airports, shopping centres, hospitals, and occasions with high traffic flow.  

automatic retractable or automatic telescoping bollards are used in high traffic areas. where deploying and retracing automatic bollards is higher in frequency. our bollards can raise or lower on command in 3 to 5 seconds.

the automatic bollards we use are pneumatic, hydraulic, and electronic piston drive systems. each system has its own unique characteristics with how it moves the automatic bollards, and also difference in their efficiency and maintenance. electronic piston drive systems uses and electric motor to push the piston within the cylinder. these systems have the highest precision control, and are also the quietest of all the other systems. pneumatic uses compressed air to move a piston in a linear motion within the cylinder. the advantages of this system are its simplicity, accuracy, minimal maintenance, and the cost being less. hydraulic systems use an in-compressible fluid being pushed by a pump within the cylinder. to give the automatic bollards their linear motion. the hydraulic system has the highest force output being almost 25 times greater force than a pneumatic system.
