Overview of Retractable Bollards: Types, Functions, Cost & Install

What Is Retractable Bollards? 

Retractable bollards , also called automatic bollards, telescopic bollards and rising bollards, are  a type of traffic barrier that can be manually or automatically retracted into the ground, allowing vehicles to pass through. Manually retractable bollards are operated with a single-key locking mechanism, while automatic bollards use hydraulic or pneumatic technology to control their movement.

Retractable bollards are typically used in locations where vehicle access needs to be restricted, such as pedestrian areas, parking lots, and private driveways.

1.1 Size of Hydraulic Bollards

The hydraulic bollards come in different sizes.
The diameters available are

168mm, 219mm, 273mm, and 325mm.

The height (above ground) options include

400mm, 600mm, 800mm, 1000mm, 1200mm, and 1500mm.

As for the thickness, you have choices of

6mm, 8mm, 10mm, 15mm, and 20mm.

1.2 What is the standard retractable bollard distance?  

According to industry standards, the general installation distance for retractable bollards is typically between 0.8 to 1.5 meters. The purpose of this installation is to effectively prevent unauthorized vehicle access while allowing pedestrians and electric bikes to pass through without hindrance.

4 Main Components of Hydraulic bollards

1. Bollard post:

304 stainless steel seamless steel pipe, with strong load-bearing and impact resistance; high waterproof level. Retractable bollards are buried in designated positions on the driveway or gate, it raises or lowers through remote control (or access control system).

2. Hydraulic transmission station:

It is composed of fuel tank, manual oil pump, a full set of hydraulic solenoid valve group, high-power motor, oil pump, oil cylinder, oil gauge, high-pressure hydraulic oil pipe, etc. It is the power source of the whole set of roadblock system, and the device is installed in retractable bollards side, used in conjunction with it.

3. Electric control system:

It is composed of PLC control board, leakage switch, non-contact noise and high-life contactor and other precise start-up time settings.
