A rising bollard is essentially a post that can be raised and lowered back into the ground either manually or automatically, although most people use the term ‘rising bollard’ to describe the automatic option. They consist of an external / ground casing into which a pump / motor assembly is mounted. The pump and motor supplies oil to a piston that extends and retracts, so pushing the post in and out of the casing and ground.

Most bollards being considered for use in a public environment should also be fitted with safety devices and visual indicators to alert people as to when the bollards are being raised / lowered. Don’t forget, as a car
approaches and a bollard is lowered, the driver will lose site of the bollard the closer he gets and without the correct safety and indicators the bollard could rise without the driver being aware.
Rising bollards can also be integrated with access control systems and traffic lights for added safety, security and convenience.
Rising bollards are used in many situations where vehicle access needs to be controlled; this could be for security or safety purposes.
The single most beneficial situation, where a rising bollard is far and away the best option, is when you want to restrict vehicle access but leave pedestrians free to enter the area, such as a maintenance road into a park.
Rising barriers are also ideal for car parks and for backing up other forms of vehicle restriction.
The advantages rising bollards have over gates and barriers is their strength, and quick operation, varying from four to ten seconds depending on the height and weight of the bollard sleeve, compared to a typical gate system which runs between 15 – 20 seconds.
Furthermore, depending on the number of bollards that are required to secure an opening they can also be more costeffective.
